Anxiety is your body’s natural response to stress. It’s a feeling of fear or apprehension about what’s to come. The first day of school, going to a job interview, or giving a speech may cause most people to feel fearful and nervous.

But if your feelings of anxiety are extreme, last for longer than six months, and are interfering with your life, you may have an anxiety disorder.

Experiencing occasional anxiety is a normal part of life. However, people with anxiety disorders frequently have intense, excessive and persistent worry and fear about everyday situations. Often, anxiety disorders involve repeated episodes of sudden feelings of intense anxiety and fear or terror that reach a peak within minutes (panic attacks).

These feelings of anxiety and panic interfere with daily activities, are difficult to control, are out of proportion to the actual danger and can last a long time. You may avoid places or situations to prevent these feelings. Symptoms may start during childhood or the teen years and continue into adulthood.

Examples of anxiety disorders include generalized anxiety disorder, social anxiety disorder (social phobia), specific phobias and separation anxiety disorder. You can have more than one anxiety disorder. Sometimes anxiety results from a medical condition that needs treatment.

What are anxiety disorders?

It’s normal to feel anxious about moving to a new place, starting a new job, or taking a test. This type of anxiety is unpleasant, but it may motivate you to work harder and to do a better job. Ordinary anxiety is a feeling that comes and goes, but does not interfere with your everyday life.

In the case of an anxiety disorder, the feeling of fear may be with you all the time. It is intense and sometimes debilitating.

This type of anxiety may cause you to stop doing things you enjoy. In extreme cases, it may prevent you from entering an elevator, crossing the street, or even leaving your home. If left untreated, the anxiety will keep getting worse.

Anxiety disorders are the most common form of emotional disorder and can affect anyone at any age. According to the American Psychiatric Association, women are more likely than men to be diagnosed with an anxiety disorder.

  • Experiencing gastrointestinal (GI) problems
  • Having difficulty controlling worry
  • Having the urge to avoid things that trigger anxiety

Several types of anxiety disorders exist:

  • Agoraphobia (ag-uh-ruh-FOE-be-uh) is a type of anxiety disorder in which you fear and often avoid places or situations that might cause you to panic and make you feel trapped, helpless or embarrassed.
  • Anxiety disorder due to a medical condition includes symptoms of intense anxiety or panic that are directly caused by a physical health problem.
  • Generalized anxiety disorder includes persistent and excessive anxiety and worry about activities or events — even ordinary, routine issues. The worry is out of proportion to the actual circumstance, is difficult to control and affects how you feel physically. It often occurs along with other anxiety disorders or depression.
  • Panic disorder involves repeated episodes of sudden feelings of intense anxiety and fear or terror that reach a peak within minutes (panic attacks). You may have feelings of impending doom, shortness of breath, chest pain, or a rapid, fluttering or pounding heart (heart palpitations). These panic attacks may lead to worrying about them happening again or avoiding situations in which they’ve occurred.
  • Selective mutism is a consistent failure of children to speak in certain situations, such as school, even when they can speak in other situations, such as at home with close family members. This can interfere with school, work and social functioning.
  • Separation anxiety disorder is a childhood disorder characterized by anxiety that’s excessive for the child’s developmental level and related to separation from parents or others who have parental roles.
  • Social anxiety disorder (social phobia) involves high levels of anxiety, fear and avoidance of social situations due to feelings of embarrassment, self-consciousness and concern about being judged or viewed negatively by others.
  • Specific phobias are characterized by major anxiety when you’re exposed to a specific object or situation and a desire to avoid it. Phobias provoke panic attacks in some people.
  • Substance-induced anxiety disorder is characterized by symptoms of intense anxiety or panic that are a direct result of misusing drugs, taking medications, being exposed to a toxic substance or withdrawal from drugs.
  • Other specified anxiety disorder and unspecified anxiety disorder are terms for anxiety or phobias that don’t meet the exact criteria for any other anxiety disorders but are significant enough to be distressing and disruptive

When to see a doctor

See your doctor if:

  • You feel like you’re worrying too much and it’s interfering with your work, relationships or other parts of your life
  • Your fear, worry or anxiety is upsetting to you and difficult to control
  • You feel depressed, have trouble with alcohol or drug use, or have other mental health concerns along with anxiety
  • You think your anxiety could be linked to a physical health problem
  • You have suicidal thoughts or behaviors — if this is the case, seek emergency treatment immediately

Your worries may not go away on their own, and they may get worse over time if you don’t seek help. See your doctor or a mental health provider before your anxiety gets worse. It’s easier to treat if you get help early.

Causes

Researchers are not sure of the exact cause of anxiety. But, it’s likely a combination of factors play a role. These include genetic and environmental factors, as well as brain chemistry.

In addition, researchers believe that the areas of the brain responsible for controlling fear may be impacted.

Current research of anxiety is taking a deeper look at the parts of the brain that are involved with anxiety.

The causes of anxiety disorders aren’t fully understood. Life experiences such as traumatic events appear to trigger anxiety disorders in people who are already prone to anxiety. Inherited traits also can be a factor.

Medical causes

For some people, anxiety may be linked to an underlying health issue. In some cases, anxiety signs and symptoms are the first indicators of a medical illness. If your doctor suspects your anxiety may have a medical cause, he or she may order tests to look for signs of a problem.

Examples of medical problems that can be linked to anxiety include:

  • Heart disease
  • Diabetes
  • Thyroid problems, such as hyperthyroidism
  • Respiratory disorders, such as chronic obstructive pulmonary disease (COPD) and asthma
  • Drug misuse or withdrawal
  • Withdrawal from alcohol, anti-anxiety medications (benzodiazepines) or other medications
  • Chronic pain or irritable bowel syndrome
  • Rare tumors that produce certain fight-or-flight hormones

Sometimes anxiety can be a side effect of certain medications.

It’s possible that your anxiety may be due to an underlying medical condition if:

  • You don’t have any blood relatives (such as a parent or sibling) with an anxiety disorder
  • You didn’t have an anxiety disorder as a child
  • You don’t avoid certain things or situations because of anxiety
  • You have a sudden occurrence of anxiety that seems unrelated to life events and you didn’t have a previous history of anxiety

Symptoms

Anxiety feels different depending on the person experiencing it. Feelings can range from butterflies in your stomach to a racing heart. You might feel out of control, like there’s a disconnect between your mind and body.

Other ways people experience anxiety include nightmares, panic attacks, and painful thoughts or memories that you can’t control. You may have a general feeling of fear and worry, or you may fear a specific place or event.

Symptoms of general anxiety include:

  • increased heart rate
  • rapid breathing
  • restlessness
  • trouble concentrating
  • difficulty falling asleep

Your anxiety symptoms might be totally different from someone else’s. That’s why it’s important to know all the ways anxiety can present itself.

Common anxiety signs and symptoms include:

  • Feeling nervous, restless or tense
  • Having a sense of impending danger, panic or doom
  • Having an increased heart rate
  • Breathing rapidly (hyperventilation)
  • Sweating
  • Trembling
  • Feeling weak or tired
  • Trouble concentrating or thinking about anything other than the present worry
  • Having trouble sleeping
  • Experiencing gastrointestinal (GI) problems
  • Having difficulty controlling worry
  • Having the urge to avoid things that trigger anxiety

What is an anxiety attack?

An anxiety attack is a feeling of overwhelming apprehension, worry, distress, or fear. For many people, an anxiety attack builds slowly. It may worsen as a stressful event approaches.

Anxiety attacks can vary greatly, and symptoms may differ among individuals. That’s because the many symptoms of anxiety don’t happen to everyone, and they can change over time.

Common symptoms of an anxiety attack include:

  • feeling faint or dizzy
  • shortness of breath
  • dry mouth
  • sweating
  • chills or hot flashes
  • apprehension and worry
  • restlessness
  • distress
  • fear
  • numbness or tingling

A panic attack and an anxiety attack share some common symptoms, but they’re not the same.

Risk factors

These factors may increase your risk of developing an anxiety disorder:

  • Trauma. Children who endured abuse or trauma or witnessed traumatic events are at higher risk of developing an anxiety disorder at some point in life. Adults who experience a traumatic event also can develop anxiety disorders.
  • Stress due to an illness. Having a health condition or serious illness can cause significant worry about issues such as your treatment and your future.
  • Stress buildup. A big event or a buildup of smaller stressful life situations may trigger excessive anxiety — for example, a death in the family, work stress or ongoing worry about finances.
  • Personality. People with certain personality types are more prone to anxiety disorders than others are.
  • Other mental health disorders. People with other mental health disorders, such as depression, often also have an anxiety disorder.
  • Having blood relatives with an anxiety disorder. Anxiety disorders can run in families.
  • Drugs or alcohol. Drug or alcohol use or misuse or withdrawal can cause or worsen anxiety.

Complications

Having an anxiety disorder does more than make you worry. It can also lead to, or worsen, other mental and physical conditions, such as:

  • Depression (which often occurs with an anxiety disorder) or other mental health disorders
  • Substance misuse
  • Trouble sleeping (insomnia)
  • Digestive or bowel problems
  • Headaches and chronic pain
  • Social isolation
  • Problems functioning at school or work
  • Poor quality of life
  • Suicide

Prevention

There’s no way to predict for certain what will cause someone to develop an anxiety disorder, but you can take steps to reduce the impact of symptoms if you’re anxious:

  • Get help early. Anxiety, like many other mental health conditions, can be harder to treat if you wait.
  • Stay active. Participate in activities that you enjoy and that make you feel good about yourself. Enjoy social interaction and caring relationships, which can lessen your worries.
  • Avoid alcohol or drug use. Alcohol and drug use can cause or worsen anxiety. If you’re addicted to any of these substances, quitting can make you anxious. If you can’t quit on your own, see your doctor or find a support group to help you.

Are there tests that diagnose anxiety?

A single test can’t diagnose anxiety. Instead, an anxiety diagnosis requires a lengthy process of physical examinations, mental health evaluations, and psychological questionnaires.

Some doctors may conduct a physical exam, including blood or urine tests to rule out underlying medical conditions that could contribute to symptoms you’re experiencing.

Several anxiety tests and scales are also used to help your doctor assess the level of anxiety you’re experiencing.

What are treatments for anxiety?

Once you’ve been diagnosed with anxiety, you can to explore treatment options with your doctor. For some people, medical treatment isn’t necessary. Lifestyle changes may be enough to cope with the symptoms.

In moderate or severe cases, however, treatment can help you overcome the symptoms and lead a more manageable day-to-day life.

Treatment for anxiety falls into two categories: psychotherapy and medication. Meeting with a therapist or psychologist can help you learn tools to use and strategies to cope with anxiety when it occurs.

Medications typically used to treat anxiety include antidepressants and sedatives. They work to balance brain chemistry, prevent episodes of anxiety, and ward off the most severe symptoms of the disorder.Treatments for anxiety disorder include: 

Medication. Several types of drugs are used to treat anxiety disorders. Talk to your doctor or psychiatrist about the pros and cons of each medicine to decide which one is best for you. 

  •  Antidepressants. Modern antidepressants (SSRIs and SNRIs) are typically the first drugs prescribed to someone with an anxiety disorder.  Examples of SSRIs are escitalopram (Lexapro) and fluoxetine (Prozac). SNRIs include duloxetine (Cymbalta)and venlafaxine (Effexor).
  • Bupropion. This is another type of antidepressant commonly used to treat chronic anxiety. It works differently than SSRIs and SNRIs.
  • Other antidepressants. These include tricyclics and monoamine oxidase inhibitors (MAOIs). They are less commonly used because side effects, like drops in blood pressure, dry mouth, blurry vision, and urinary retention, can be unpleasant or unsafe for some people.  
  • Benzodiazepines. Your doctor may prescribe one of these drugs if you’re having persistent panicky feelings or anxiety. They help lower anxiety. Examples are alprazolam (Xanax) and clonazepam (Klonopin). They work quickly, but you can become dependent on them. Usually, they’re meant to be an add-on to your anxiety disorder treatment and you shouldn’t take them for a long time. 
  • Beta-blockers. This type of high blood pressure drug can help you feel better if you’re having physical symptoms of anxiety, such as a racing heart, trembling, or shaking.  A beta-blocker may help you relax during an acute anxiety attack.
  • Anticonvulsants. Used to prevent seizures in people with epilepsy, these drugs also can relieve certain anxiety disorder symptoms. 
  • Antipsychotics. Low doses of these drugs can be added to help make other treatments work better. 
  • Buspirone (BuSpar). This anti-anxiety drug is sometimes used to treat chronic anxiety. You’ll need to take it for a few weeks before seeing full symptom relief. 

Psychotherapy: This is a type of counseling that helps you learn how your emotions affect your behaviors. It’s sometimes called talk therapy. A trained mental health specialist listens and talks to you about your thoughts and feelings and suggests ways to understand and manage them and your anxiety disorder.

  • Cognitive behavioral therapy (CBT): This common type of psychotherapy teaches you how to turn negative, or panic-causing, thoughts and behaviors into positive ones. You’ll learn ways to carefully approach and manage fearful or worrisome situations without anxiety. Some places offer family CBT sessions.

What natural remedies are used for anxiety?

Lifestyle changes can be an effective way to relive some of the stress and anxiety you may cope with every day. Most of the natural “remedies” consist of caring for your body, participating in healthy activities, and eliminating unhealthy ones.

These include:

  • getting enough sleep
  • meditating
  • staying active and exercising
  • eating a healthy diet
  • staying active and working out
  • avoiding alcohol
  • avoiding caffeine
  • quitting smoking cigarettes

Psychiatric disorders of childhood and adolescence

REQUEST AN APPOINTMENT OR BOOK A CONSULANT – Sargam.dange.18@gmail.com

Although it is sometimes assumed that childhood and adolescence are times of carefree bliss, as many as 20% of children and adolescents have a diagnosable mental disorder that causes impairment. With increasing age, more children develop one or more disorders. All told, about 27.9% of US adolescents aged 13 to 17 are reported to meet criteria for 2 or more disorders. Recent studies that follow children from birth to adulthood indicate that most adult mental health disorders begin in early childhood and adolescence. Genes associated with mental health disorders have been reported to show high expression throughout the lifespan, beginning in the 2nd trimester and impacting neurodevelopmental processes, which may explain the early ages of onset. Most of these disorders may be viewed as exaggerations or distortions of normal behaviors and emotions.

Like adults, children and adolescents vary in temperament. Some are shy and reticent; others are socially exuberant. Some are methodical and cautious; others are impulsive and careless. Whether a child is behaving like a typical child or has a disorder is determined by the presence of impairment and the degree of distress related to the symptoms. For example, a 12-year-old girl may be frightened by the prospect of delivering a book report in front of her class. This fear would be viewed as social anxiety disorder only if her fears were severe enough to cause significant distress and avoidance.

There is much overlap between the symptoms of many disorders and the challenging behaviors and emotions of normal children. Thus, many strategies useful for managing behavioral problems in children can also be used in children who have mental disorders. Furthermore, appropriate management of childhood behavioral problems may decrease the risk of temperamentally vulnerable children developing a full-blown disorder. Also, effective treatment of some disorders (eg, anxiety) during childhood may decrease the risk of mood disorders later in life.

The most common mental disorders of childhood and adolescence fall into the following categories:

  • Anxiety disorders
  • Stress-related disorders
  • Mood disorders
  • Obsessive-compulsive disorder
  • Disruptive behavioral disorders (eg, attention-deficit/hyperactivity disorder [ADHD], conduct disorder, and oppositional defiant disorder)

Schizophrenia and related psychotic disorders are much less common.

Pediatric catatonia is more common than childhood schizophrenia. It may represent a psychiatric disorder but often occurs in medical conditions (eg, infections, metabolic disorders, autoimmune conditions) and is not detected by pediatricians.

However, more often than not, children and adolescents have symptoms and problems that cut across diagnostic boundaries. For example, > 25% of children with ADHD also have an anxiety disorder, and 25% meet the criteria for a mood disorder.

Sign of Mental Illness in Children

Nightmares

Nightmares are dreams that are threatening and scary. Nearly everyone has had a nightmare from time to time. For trauma survivors, though, nightmares are a common problem. Along with flashbacks and unwanted memories, nightmares are one of the ways in which a trauma survivor may relive the trauma for months or years after the event.

What are symptoms and signs of mental illness in children?

Children with mental illness may experience the classic symptoms of their particular disorder but may exhibit other symptoms as well, including

  • poor school performance;
  • persistent boredom;
  • frequent complaints of physical symptoms, such as headaches and stomachaches;
  • sleep and/or appetite problems like sleeping too much or too little, nightmares, or sleepwalking;
  • behaviors returning to those of a younger age (regressing), like bedwetting, throwing tantrums, or becoming clingy;
  • noncompliant or aggressive behaviors; and
  • more risk-taking behaviors and/or showing less concern for their own safety.

Examples of risk-taking behaviors include running into the street, climbing too high, engaging in physical altercations, or playing with unsafe items.

What are causes and risk factors for mental illness in children?

As is the case with most mental health disorders at any age, such disorders in children do not have one single definitive cause. Rather, people with these illnesses tend to have a number of biological, psychological, and environmental risk factors that contribute to their development. Biologically, mental illnesses tend to be associated with abnormal levels of neurotransmitters, like serotonin or dopamine in the brain, a decrease in the size of some areas of the brain, as well as increased activity in other areas of the brain. Physicians are more likely to diagnose girls with mood disorders like depression and anxiety compared to boys, while disorders like attention deficit hyperactivity disorder and autism spectrum disorders are more often assigned to boys. Gender differences in mental illness are the result of, among other things, a combination of biological differences based on gender, as well as the differences in how girls are encouraged to interpret their environment and respond to it compared to boys. There is thought to be at least a partially genetic contribution to the fact that children and adolescents with a mentally ill parent are up to four times more likely to develop such an illness themselves. Teens who develop a mental disorder are also more prone to having had other biological challenges, like low birth weight, trouble sleeping, and having a mother younger than 18 years old at the time of their birth.

Psychological risk factors for mental illness in children include low self-esteem, poor body image, a tendency to be highly self-critical, and feeling helpless when dealing with negative events. Teen mental disorders are somewhat associated with the stress of body changes, including the fluctuating hormones of puberty, as well as teen ambivalence toward increased independence, and with changes in their relationships with parents, peers, and others. Teenagers who suffer from conduct disorder, attention deficit hyperactivity disorder (ADHD), clinical anxiety, or who have cognitive and learning problems, as well as trouble relating to others are at higher risk of also developing a mental disorder.

Childhood mental illness may be a reaction to environmental stresses, including trauma like being the victim of verbal, physical, or sexual abuse, the death of a loved one, school problems, or being the victim of bullying or peer pressure. Gay teens are at higher risk for developing mental disorders like depression, thought to be because of the bullying by peers and potential rejection by family members. Children in military families are at risk for experiencing depression as well.

The aforementioned environmental risk factors tend to predispose individuals to childhood mental illness. Other risk factors tend to predispose people to developing a mental disorder at any age. Such nonspecific risk factors include a history of poverty, exposure to violence, having an antisocial peer group, or being socially isolated, abuse victimization, parental conflict, and family dissolution. Children who have low physical activity, poor academic performance, or lose a relationship are at higher risk for mental illness as well.

How do health care professionals diagnose mental illness in children?

Many health care professionals may help make the diagnosis of a mental illness in children, including licensed mental health therapists, pediatricians or other primary care providers, emergency physicians, psychiatrists, psychologists, psychiatric nurses, physician assistants, and social workers. One of these professionals will likely conduct an extensive medical interview and physical examination or refer the child for those assessments as part of establishing the diagnosis.

Childhood mental illnesses may be associated with a number of other medical conditions or can be a side effect of various medications. For this reason, health care professionals perform routine laboratory tests during the initial evaluation to rule out other causes of symptoms. Occasionally, it may be necessary to get an X-ray, scan, or other imaging study. As part of this examination, a health care provider may ask the child and his or her parents a series of questions from a standardized questionnaire or self-test to help further assess symptoms. The use of screening tools is particularly important for detecting early signs of mental illness in infants and toddlers, due to their being largely preverbal in their communication.

RESPONSE OF WHO

Childhood and adolescence are critical stages of life for mental health. This is a time when rapid growth and development take place in the brain. Children and adolescents acquire cognitive and social-emotional skills that shape their future mental health and are important for assuming adult roles in society.

The quality of the environment where children and adolescents grow up shapes their well-being and development. Early negative experiences in homes, schools, or digital spaces, such as exposure to violence, the mental illness of a parent or other caregiver, bullying and poverty, increase the risk of mental illness.

Mental health conditions, such as childhood epilepsy, developmental disabilities, depression, anxiety and behavioural disorders, are major causes of illness and disability among young people. Worldwide, 10-20% of children and adolescents experience mental health conditions, but the majority of them do not seek help or receive care. Half of all mental health conditions start by 14 years of age. Suicide is the third leading cause of death in 15-19 year-olds. The consequences of not addressing mental health and psychosocial development for children and adolescents extend to adulthood and limit opportunities for leading fulfilling lives. 

WHO supports Member States in the development and implementation of multisectoral, evidence-informed and human-rights-based strategies for the promotion of mental health, prevention of mental health conditions and provision of mental health care for children, adolescents and their families.

Psychological testing

REQUEST AN APPOINTMENT OR BOOK A CONSULANT – Sargam.dange.18@gmail.com

Psychological tests are written, visual, or verbal evaluations administered to assess the cognitive and emotional functioning of children and adults.

Purpose

Psychological tests are used to assess a variety of mental abilities and attributes, including achievement and ability, personality, and neurological functioning.

For children, academic achievement, ability, and intelligence tests may be used as tools in school placement, in determining the presence of a learning disability or a developmental delay , in identifying giftedness, or in tracking intellectual development. Intelligence testing may also be used with teens and young adults to determine vocational ability (e.g., in career counseling).

Personality tests are administered for a wide variety of reasons, from diagnosing psychopathology (e.g., personality disorder, depressive disorder) to screening job candidates. They may be used in an educational setting to determine personality strengths and weaknesses.

Types of Psychological Testing

Psychological testing — also called psychological assessment — is the foundation of how psychologists better understand a person and their behavior. It is a process of problem solving for many professionals — to try and determine the core components of a person’s psychological or mental health problems, personality, IQ, or some other component. It is also a process that helps identifies not just weaknesses of a person, but also their strengths.

Psychological testing measures an individual’s performance at a specific point in time — right now. Psychologists talk about a person’s “present functioning” in terms of their test data. Therefore psychological tests can’t predict future or innate potential.

Psychological testing is not a single test or even a single type of test. It encompasses a whole body of dozens of research-backed tests and procedures of assessing specific aspects of a person’s psychological makeup. Some tests are used to determine IQ, others are used for personality, and still others for something else. Since so many different tests are available, it’s important to note that not all of them share the same research evidence for their use — some tests have a strong evidence base while others do not.

Psychological assessment is something that’s typically done in a formal manner only by a licensed psychologist (the actual testing may sometimes be administered by a psychology intern or trainee studying to become a psychologist). Depending upon what kind of testing is being done, it can last anywhere from 1 1/2 hours to a full day. Testing is usually done in a psychologist’s office and consists largely of paper-and-pencil tests (nowadays often administered on a computer for ease-of-use).

Psychological testing is divided into four primary types:

  • Clinical Interview
  • Assessment of Intellectual Functioning (IQ)
  • Personality Assessment
  • Behavioral Assessment

In addition to these primary types of psychological assessment, other kinds of psychological tests are available for specific areas, such as aptitude or achievement in school, career or work counseling, management skills, and career planning.

The Clinical Interview

The clinical interview is a core component of any psychological testing. Some people know the clinical interview as an “intake interview”, “admission interview” or “diagnostic interview” (although technically these are often very different things). Clinical interviews typically last from 1 to 2 hours in length, and occur most often in a clinician’s office. Many types of mental health professionals can conduct a clinical interview — psychologists, psychiatrists, clinical social workers, psychiatric nurses, amongst others.

The clinical interview is an opportunity for the professional to gather important background and family data about the person. Think of it as an information-gathering session for the professional’s benefit (but ultimately for your benefit). You may have to recall or review a lot of your life and personal history with the professional, who will often ask specific questions about various stages in your life.

Some components of the clinical interview have now become computerized, meaning you will answer a series of questions on a computer in the clinician’s office instead of talking directly to a person. This is most often done for basic demographic information, but can also include structured diagnostic interview questions to help the clinicians formulate an initial diagnostic impression.

Before any formal psychological testing is done, a clinical interview is nearly always conducted (even if the person has already gone through one with a different professional). Psychologists conducting the testing will often want to form their own clinical impressions, which can be best done through a direct interview with the person.

Assessment of Intellectual Functioning (IQ)

Your IQ — intellectual quotient — is a theoretical construct of a measure of general intelligence. It’s important to note that IQ tests do not measure actual intelligence — they measure what we believe might be important components of intelligence.

There are two primary measures used to test a person’s intellectual functions — intelligence tests and neuropsychological assessment. Intelligence tests are the more common type administered and include the Stanford-Binet and the Wechsler scales. Neuropsychological assessment — which can take up to 2 days to administer — is a far more extensive form of assessment. It is focused not just on testing for intelligence, but also on determining all of the cognitive strengths and deficits of the person. Neuropsychological assessment is most usually done with people who have suffered some sort of brain damage, dysfunction or some kind of organic brain problem, just as having a brain hemorrhage.

The most commonly administered IQ test is called the Wechsler Adult Intelligence Scale—Fourth Edition (WAIS-IV). It generally takes anywhere from an hour to an hour and a half to administer, and is appropriate for any individual aged 16 or older to take. (Children can be administered an IQ test especially designed for them called the Wechsler Intelligence Scale for Children – Fourth Edition, or the WISC-IV.)

The WAIS-IV is divided into four major scales to arrive at what’s called a “full scale IQ.” Each scale is further divided into a number of mandatory and optional (also called supplemental) subtests. The mandatory subtests are necessary to arrive at a person’s full scale IQ. The supplemental subtests provide additional, valuable information about a person’s cognitive abilities.

Verbal Comprehension Scale

  • Similarities
  • Vocabulary
  • Information
  • Supplemental Subtest: Comprehension

Perceptual Reasoning Scale

  • Block Design
  • Matrix Reasoning
  • Visual Puzzles
  • Supplemental Subtests: Picture Completion; Figure Weights (16-69) only

REQUEST AN APPOINTMENT OR BOOK A CONSULANT – Sargam.dange.18@gmail.com

Working Memory Scale

  • Digit Span
  • Arithmetic
  • Supplemental Subtest: Letter-Number Sequencing (16-69 only)

Processing Speed Scale

  • Symbol Search
  • Coding
  • Supplemental Subtest: Cancellation (16-69 only)

As you can surmise from the names of some of the scales of the test, measuring IQ isn’t just answering questions about information or vocabulary. Because some of the subtests require physical manipulation of objects, the Wechsler is tapping into many different components of a person’s brain and thought processes (including the creative). For this reason and others, online IQ tests are not equivalent to real IQ tests given by a psychologist.

Personality Assessment

Personality assessment is designed to help a professional better understand an individual’s personality. Personality is a complex combination of factors that has been developed over a person’s entire childhood and young adulthood. There are genetic, environmental and social components to personality — our personalities are not shaped by one single influence. Therefore tests that measure personality take into account this complexity and rich texture.

There are two primary types of personality tests — objective, by far the most commonly used today, and projective. Objective tests include things like the Minnesota Multiphasic Personality Inventory (MMPI-2), the 16PF, and the Millon Clinical Multiaxial Inventory-III (MCMI-III). Projective tests include the Rorschach Inkblot Test, the Thematic Apperception Test (TAT), and the Draw-a-Person test.

Objective Tests

The most common objective personality test is the MMPI-2, a 567 true/false test that is a good measure of dysfunction within personality. It is less useful as a measure of healthy or positive personality traits, because its design was based on helping a professional to find a psychiatric diagnostic label that best suited an individual. Originally developed in the 1940s, it was significantly revised in 1989 (and had another minor revision in 2001).

The MMPI-2 measures personality traits such as paranoia, hypomania, social introversion, masculinity/femininity, and psychopathology, among others. It does this by connecting an individual’s responses to dozens of questions scattered throughout the test that are positively or negatively correlated with a particular personality trait. Because the questions are not always obviously related to the trait to which they are correlated, it is difficult to “fake” this test. The MMPI-2 is most often self-administered on a computer in a clinician’s office.

The Millon (MCMI-III) is specifically used to arrive at a DSM-IV personality disorder diagnosis. Because it takes only about a third of the time to take as the MMPI-2, it is often preferred when a simple assessment of an individual’s personality disorder is needed.

Because the MMPI-2 is not an ideal measure for people with healthy personalities, other measures, such as the 16PF may be more appropriate. The 16PF measures 16 basic personality traits and can help a person better understand where their personality falls amongst those traits:

  1. Warmth (Reserved vs. Warm; Factor A)
  2. Reasoning (Concrete vs. Abstract; Factor B)
  3. Emotional Stability (Reactive vs. Emotionally Stable; Factor C)
  4. Dominance (Deferential vs. Dominant; Factor E)
  5. Liveliness (Serious vs. Lively; Factor F)
  6. Rule-Consciousness (Expedient vs. Rule-Conscious; Factor G)
  7. Social Boldness (Shy vs. Socially Bold; Factor H)
  8. Sensitivity (Utilitarian vs. Sensitive; Factor I)
  9. Vigilance (Trusting vs. Vigilant; Factor L)
  10. Abstractedness (Grounded vs. Abstracted; Factor M)
  11. Privateness (Forthright vs. Private; Factor N)
  12. Apprehension (Self-Assured vs. Apprehensive; Factor O)
  13. Openness to Change (Traditional vs. Open to Change; Factor Q1)
  14. Self-Reliance (Group-Oriented vs. Self-Reliant; Factor Q2)
  15. Perfectionism (Tolerates Disorder vs. Perfectionistic; Factor Q3)
  16. Tension (Relaxed vs. Tense; Factor Q4)

This type of assessment might be administered so that a person can better understand themselves, and it can also help a professional better understand what type of approach or strategy to employ in treatment to best help the person.

Projective Tests

The most famous projective test is the Rorschach Inkblot Test. The test is composed 5 black and white inkblot cards and 5 colored inkblot cards that an individual is shown and then asked to tell the professional what they see. The most popular scoring system for the Rorschach is the Exner system, developed in the 1970s. Responses are scored based the location described in the inkblot, and its determinants — the things in the blot that prompted the person’s response. So yes, for the Rorschach there are answers that are “more right” than others.

The Thematic Apperception Test (TAT) is comprised of 31 cards that depict people in a variety of situations. A few contain only objects and one card is completely blank. Often only a small subset of the cards is given (such as 10 or 20). The person viewing the card is asked to make up a story about what they see. The TAT is not often formally scored; instead it’s a test designed to try and distinguish recurring themes in the person’s life. The pictures themselves have no inherent or “correct” story; therefore anything a person says about the picture may be an unconscious reflection into the person’s life or inner turmoil.

Behavioral Assessment

Behavioral assessment is the process of observing or measuring a person’s actual behavior to try and better understand the behavior and the thoughts behind it, and determine possible reinforcing components or triggers for the behavior. Through the process of behavioral assessment, a person — and/or a professional — can track behaviors and help change them.

After a clinical interview, the core of behavioral assessment is naturalistic observation — that is, observing the person in a natural setting and taking notes (much like an anthropologist). This can be done at home (think “Super Nanny” when Nanny spends the first day simply observing the current family patterns of behavior), at school, at work, or in a hospital or inpatient setting. Target negative and positive behaviors are observed, as well as their respective reinforcements. Then the therapist has a good idea of what needs to change in order to obtain new, healthier behaviors.

Self-monitoring is also a component of behavioral assessment. For instance, when a person is asked to keep a mood journal and track their moods over the course of a week or month, that’s a form of self-monitoring.

Inventories and checklists, popular nowadays online in the form of quizzes, can also be a form of behavioral assessment. For instance, the Beck Depression Inventory is a popular depression behavioral assessment.

Psychological assessment encompasses a wide variety of types of tests, procedures and techniques used to help a psychologist better understand a person. Once psychological testing has been completed, the professional typically requires a few weeks to compile the data, interpret it, and write up a personalized assessment report for the individual.

Such reports are usually lengthy and try to tie together the findings from all the various tests administered (if more than one test was administered). Findings that are outliers — e.g., only one test suggests something is significant but it is not backup by other tests — may be noted, but aren’t as significant as thematic findings that run through all the tests. The point of the test report is to summarize the findings in plain English, identify strengths and weaknesses, and help shed light on a person to help them better understand themselves.

The old saying, “Know thyself” comes to mind. When used responsibly in a clinical or school setting, psychological testing has been shown to help individuals better “know thyself” in ways that simply talking to a person might never discover.

Aetiology of Psychiatric disorders

REQUEST AN APPOINTMENT OR BOOK A CONSULANT – Sargam.dange.18@gmail.com

Mental illness, also called mental health disorders, refers to a wide range of mental health conditions — disorders that affect your mood, thinking and behavior. Examples of mental illness include depression, anxiety disorders, schizophrenia, eating disorders and addictive behaviors.

Many people have mental health concerns from time to time. But a mental health concern becomes a mental illness when ongoing signs and symptoms cause frequent stress and affect your ability to function.

A mental illness can make you miserable and can cause problems in your daily life, such as at school or work or in relationships. In most cases, symptoms can be managed with a combination of medications and talk therapy (psychotherapy).

Symptoms

Signs and symptoms of mental illness can vary, depending on the disorder, circumstances and other factors. Mental illness symptoms can affect emotions, thoughts and behaviors.

Examples of signs and symptoms include:

  • Feeling sad or down
  • Confused thinking or reduced ability to concentrate
  • Excessive fears or worries, or extreme feelings of guilt
  • Extreme mood changes of highs and lows
  • Withdrawal from friends and activities
  • Significant tiredness, low energy or problems sleeping
  • Detachment from reality (delusions), paranoia or hallucinations
  • Inability to cope with daily problems or stress
  • Trouble understanding and relating to situations and to people
  • Problems with alcohol or drug use
  • Major changes in eating habits
  • Sex drive changes
  • Excessive anger, hostility or violence
  • Suicidal thinking

Sometimes symptoms of a mental health disorder appear as physical problems, such as stomach pain, back pain, headaches, or other unexplained aches and pains.

When to see a doctor

If you have any signs or symptoms of a mental illness, see your primary care provider or a mental health professional. Most mental illnesses don’t improve on their own, and if untreated, a mental illness may get worse over time and cause serious problems.

If you have suicidal thoughts

Suicidal thoughts and behavior are common with some mental illnesses. If you think you may hurt yourself or attempt suicide, get help right away:

  • Call your local emergency number immediately.
  • Call your mental health specialist.
  • Call a suicide hotline number.
  • Seek help from your primary care provider.
  • Reach out to a close friend or loved one.
  • Contact a minister, spiritual leader or someone else in your faith community.

Suicidal thinking doesn’t get better on its own — so get help.

Helping a loved one

If your loved one shows signs of mental illness, have an open and honest discussion with him or her about your concerns. You may not be able to force someone to get professional care, but you can offer encouragement and support. You can also help your loved one find a qualified mental health professional and make an appointment. You may even be able to go along to the appointment.

Causes

Mental illnesses, in general, are thought to be caused by a variety of genetic and environmental factors:

  • Inherited traits. Mental illness is more common in people whose blood relatives also have a mental illness. Certain genes may increase your risk of developing a mental illness, and your life situation may trigger it.
  • Environmental exposures before birth. Exposure to environmental stressors, inflammatory conditions, toxins, alcohol or drugs while in the womb can sometimes be linked to mental illness.
  • Brain chemistry. Neurotransmitters are naturally occurring brain chemicals that carry signals to other parts of your brain and body. When the neural networks involving these chemicals are impaired, the function of nerve receptors and nerve systems change, leading to depression and other emotional disorders.

What Biological Factors Are Involved in Mental Illness?

Some mental illnesses have been linked to abnormal functioning of nerve cell circuits or pathways that connect particular brain regions. Nerve cells within these brain circuits communicate through chemicals called neurotransmitters. “Tweaking” these chemicals — through medicines, psychotherapy or other medical procedures — can help brain circuits run more efficiently. In addition, defects in or injury to certain areas of the brain have also been linked to some mental conditions.

Other biological factors that may be involved in the development of mental illness include:

  • Genetics (heredity): Mental illnesses sometimes run in families, suggesting that people who have a family member with a mental illness may be somewhat more likely to develop one themselves. Susceptibility is passed on in families through genes. Experts believe many mental illnesses are linked to abnormalities in many genes rather than just one or a few and that how these genes interact with the environment is unique for every person (even identical twins). That is why a person inherits a susceptibility to a mental illness and doesn’t necessarily develop the illness. Mental illness itself occurs from the interaction of multiple genes and other factors — such as stress, abuse, or a traumatic event — which can influence, or trigger, an illness in a person who has an inherited susceptibility to it.
  • Infections: Certain infections have been linked to brain damage and the development of mental illness or the worsening of its symptoms. For example, a condition known as pediatric autoimmune neuropsychiatric disorder (PANDAS) associated with the Streptococcus bacteria has been linked to the development of obsessive-compulsive disorder and other mental illnesses in children.
  • Brain defects or injury: Defects in or injury to certain areas of the brain have also been linked to some mental illnesses.
  • Prenatal damage: Some evidence suggests that a disruption of early fetal brain development or trauma that occurs at the time of birth — for example, loss of oxygen to the brain — may be a factor in the development of certain conditions, such as autism spectrum disorder.
  • Substance abuse: Long-term substance abuse, in particular, has been linked to anxiety, depression, and paranoia.
  • Other factors: Poor nutrition and exposure to toxins, such as lead, may play a role in the development of mental illnesses.

What Psychological Factors Contribute to Mental Illness?

Psychological factors that may contribute to mental illness include:

  • Severe psychological trauma suffered as a child, such as emotional, physical, or sexual abuse
  • An important early loss, such as the loss of a parent
  • Neglect
  • Poor ability to relate to others

What Environmental Factors Contribute to Mental Illness?

Certain stressors can trigger an illness in a person who is susceptible to mental illness. These stressors include:

  • Death or divorce
  • A dysfunctional family life
  • Feelings of inadequacy, low self-esteem, anxiety, anger, or loneliness
  • Changing jobs or schools
  • Social or cultural expectations (For example, a society that associates beauty with thinness can be a factor in the development of eating disorders.)
  • Substance abuse by the person or the person’s parents

Risk factors

Certain factors may increase your risk of developing a mental illness, including:

  • A history of mental illness in a blood relative, such as a parent or sibling
  • Stressful life situations, such as financial problems, a loved one’s death or a divorce
  • An ongoing (chronic) medical condition, such as diabetes
  • Brain damage as a result of a serious injury (traumatic brain injury), such as a violent blow to the head
  • Traumatic experiences, such as military combat or assault
  • Use of alcohol or recreational drugs
  • A childhood history of abuse or neglect
  • Few friends or few healthy relationships
  • A previous mental illness

Mental illness is common. About 1 in 5 adults has a mental illness in any given year. Mental illness can begin at any age, from childhood through later adult years, but most cases begin earlier in life.

The effects of mental illness can be temporary or long lasting. You also can have more than one mental health disorder at the same time. For example, you may have depression and a substance use disorder.

Complications

Mental illness is a leading cause of disability. Untreated mental illness can cause severe emotional, behavioral and physical health problems. Complications sometimes linked to mental illness include:

  • Unhappiness and decreased enjoyment of life
  • Family conflicts
  • Relationship difficulties
  • Social isolation
  • Problems with tobacco, alcohol and other drugs
  • Missed work or school, or other problems related to work or school
  • Legal and financial problems
  • Poverty and homelessness
  • Self-harm and harm to others, including suicide or homicide
  • Weakened immune system, so your body has a hard time resisting infections
  • Heart disease and other medical conditions

Prevention

There’s no sure way to prevent mental illness. However, if you have a mental illness, taking steps to control stress, to increase your resilience and to boost low self-esteem may help keep your symptoms under control. Follow these steps:

  • Pay attention to warning signs. Work with your doctor or therapist to learn what might trigger your symptoms. Make a plan so that you know what to do if symptoms return. Contact your doctor or therapist if you notice any changes in symptoms or how you feel. Consider involving family members or friends to watch for warning signs.
  • Get routine medical care. Don’t neglect checkups or skip visits to your primary care provider, especially if you aren’t feeling well. You may have a new health problem that needs to be treated, or you may be experiencing side effects of medication.
  • Get help when you need it. Mental health conditions can be harder to treat if you wait until symptoms get bad. Long-term maintenance treatment also may help prevent a relapse of symptoms.
  • Take good care of yourself. Sufficient sleep, healthy eating and regular physical activity are important. Try to maintain a regular schedule. Talk to your primary care provider if you have trouble sleeping or if you have questions about diet and physical activity.

  • performance,
  • decision making,
  • cooperation
  • conflict

Every organization is a group unto itself. A group refers to two or more people who share a common meaning and evaluation of themselves and come together to achieve common goals. In other words, a group is a collection of people who interact with one another; accept rights and obligations as members and who share a common identity.

What is Group Dynamics?

Group dynamics deals with the attitudes and behavioral patterns of a group. Group dynamics concern how groups are formed, what is their structure and which processes are followed in their functioning. Thus, it is concerned with the interactions and forces operating between groups.

Group dynamics is relevant to groups of all kinds – both formal and informal. If the UPA government has set up Group of Ministers for every governance issue, the Supreme Court of India has 27 Group of Judges committees overseeing all manner of non-judicial work in the apex court. In an organizational setting, the term groups are a very common and the study of groups and group dynamics is an important area of study.

Characteristics of a Group:

Regardless of the size or the purpose, every group has similar characteristics:

(a) 2 or more persons (if it is one person, it is not a group)

(b) Formal social structure (the rules of the game are defined)

(c) Common fate (they will swim together)

(d) Common goals (the destiny is the same and emotionally connected)

(e) Face-to-face interaction (they will talk with each other)

(f) Interdependence (each one is complimentary to the other)

(g) Self-definition as group members (what one is who belongs to the group)

(h) Recognition by others (yes, you belong to the group).

Process/Stages of Group Development/Evolution:

Group Development is a dynamic process. How do groups evolve? There is a process of five stages through which groups pass through. The process includes the five stages: forming, storming, forming, performing, and adjourning.

Forming:

The first stage in the life of a group is concerned with forming a group. This stage is characterized by members seeking either a work assignment (in a formal group) or other benefit, like status, affiliation, power, etc. (in an informal group). Members at this stage either engage in busy type of activity or show apathy.

Storming:

The next stage in this group is marked by the formation of dyads and triads. Members seek out familiar or similar individuals and begin a deeper sharing of self. Continued attention to the subgroup creates a differentiation in the group and tensions across the dyads / triads may appear. Pairing is a common phenomenon. There will be conflict about controlling the group.

Norming:

The third stage of group development is marked by a more serious concern about task performance. The dyads/triads begin to open up and seek out other members in the group. Efforts are made to establish various norms for task performance.

Members begin to take greater responsibility for their own group and relationship while the authority figure becomes relaxed. Once this stage is complete, a clear picture will emerge about hierarchy of leadership. The norming stage is over with the solidification of the group structure and a sense of group identity and camaraderie.

Performing:

This is a stage of a fully functional group where members see themselves as a group and get involved in the task. Each person makes a contribution and the authority figure is also seen as a part of the group. Group norms are followed and collective pressure is exerted to ensure the Process of Group effectiveness of the group.

The group may redefine its goals Development in the light of information from the outside environment and show an autonomous will to pursue those goals. The long-term viability of the group is established and nurtured.

Adjourning:

In the case of temporary groups, like project team, task force, or any other such group, which have a limited task at hand, also have a fifth stage, This is known as adjourning.

The group decides to disband. Some members may feel happy over the performance, and some may be unhappy over the stoppage of meeting with group members. Adjourning may also be referred to as mourning, i.e. mourning the adjournment of the group.

The readers must note that the four stages of group development mentioned above for permanent groups are merely suggestive. In reality, several stages may go on simultaneously.

Types of Groups:

One way to classify the groups is by way of formality – formal and informal. While formal groups are established by an organization to achieve its goals, informal groups merge spontaneously. Formal groups may take the form of command groups, task groups, and functional groups.

1. Command Groups:

Command groups are specified by the organizational chart and often consist of a supervisor and the subordinates that report to that supervisor. An example of a command group is a market research firm CEO and the research associates under him.

2. Task Groups:

Task groups consist of people who work together to achieve a common task. Members are brought together to accomplish a narrow range of goals within a specified time period. Task groups are also commonly referred to as task forces. The organization appoints members and assigns the goals and tasks to be accomplished.

Examples of assigned tasks are the development of a new product, the improvement of a production process, or designing the syllabus under semester system.

Other common task groups are ad hoc committees, project groups, and standing committees. Ad hoc committees are temporary groups created to resolve a specific complaint or develop a process are normally disbanded after the group completes the assigned task.

3. Functional Groups:

A functional group is created by the organization to accomplish specific goals within an unspecified time frame. Functional groups remain in existence after achievement of current goals and objectives. Examples of functional groups would be a marketing department, a customer service department, or an accounting department.

In contrast to formal groups, informal groups are formed naturally and in response to the common interests and shared values of individuals. They are created for purposes other than the accomplishment of organizational goals and do not have a specified time frame. Informal groups are not appointed by the organization and members can invite others to join from time to time.

Informal groups can have a strong influence in organizations that can either be positive or negative. For example, employees who form an informal group can either discuss how to improve a production process or how to create shortcuts that jeopardize quality. Informal groups can take the form of interest groups, friendship groups, or reference groups.

i. Interest Group:

Interest groups usually continue over time and may last longer than general informal groups. Members of interest groups may not be part of the same organizational department but they are bound together by some other common interest.

The goals and objectives of group interests are specific to each group and may not be related to organizational goals and objectives. An example of an interest group would be students who come together to form a study group for a specific class.

ii. Friendship Groups:

Friendship groups are formed by members who enjoy similar social activities, political beliefs, religious values, or other common bonds. Members enjoy each other’s company and often meet after work to participate in these activities. For example, a group of employees who form a friendship group may have a yoga group, a Rajasthani association in Delhi, or a kitty party lunch once a month.

iii. Reference Groups:

A reference group is a type of group that people use to evaluate themselves. The main objectives of reference groups are to seek social validation and social comparison. Social validation allows individuals to justify their attitudes and values while social comparison helps individuals evaluate their own actions by comparing themselves to others. Reference groups have a strong influence on members’ behavior. Such groups are formed voluntarily. Family, friends, and religious affiliations are strong reference groups for most individuals.

Factors Affecting Group Behaviour:

The success or failure of a group depends upon so many factors. Group member resources, structure (group size, group roles, group norms, and group cohesiveness), group processes (the communication, group decision making processes, power dynamics, conflicting interactions, etc.) and group tasks (complexity and interdependence).

1. Group Member Resources:

The members’ knowledge, abilities, skills; and personality characteristics (sociability, self- reliance, and independence) are the resources the group members bring in with them. The success depends upon these resources as useful to the task.

2. Group Structure:

Group Size:

Group size can vary from 2 people to a very large number of people. Small groups of two to ten are thought to be more effective because each member has ample opportunity to take part and engage actively in the group. Large groups may waste time by deciding on processes and trying to decide who should participate next.

Evidence supports the notion that as the size of the group increases, satisfaction increases up to a certain point. Increasing the size of a group beyond 10-12 members’ results in decreased satisfaction. It is increasingly difficult for members of large groups to identify with one another and experience cohesion.

Group Roles:

In formal groups, roles are always predetermined and assigned to members. Each role shall have specific responsibilities and duties. There are, however, emergent roles that develop naturally to meet the needs of the groups.

These emergent roles will often substitute the assigned roles as individuals begin to express themselves and become more assertive. Group roles can then be classified into work roles, maintenance roles, and blocking roles.

Work roles are task-oriented activities that involve accomplishing the group’s goals. They involve a variety of specific roles such as initiator, informer, clarifier, summarizer, and reality tester.

Maintenance roles are social-emotional activities that help members maintain their involvement in the group and raise their personal commitment to the group. The maintenance roles are harmonizer, gatekeeper, consensus tester, encourager, and compromiser.

clip_image006

Blocking roles are activities that disrupt the group. Blockers will stubbornly resist the group’s ideas, disagree with group members for personal reasons, and will have hidden agendas. They may take the form of dominating discussions, verbally attacking other group members, and distracting the group with trivial information or unnecessary humour.

Often times the blocking behaviour may not be intended as negative. Sometimes a member may share a joke in order to break the tension, or may question a decision in order to force group members to rethink the issue. The blocking roles are aggressor, blocker, dominator, comedian, and avoidance behaviour.

Role conflicts arise when there is ambiguity (confusion about delegation and no specific job descriptions) between the sent role and the received role which leads to frustration and dissatisfaction, ultimately leading to turnover; inconsistency between the perceived role and role behaviour (conflict between work roles and family roles); and conflicting demands from different sources while performing the task.

Group Norms:

Norms define the acceptable standard or boundaries of acceptable and unacceptable behaviour, shared by group members. They are typically created in order to facilitate group survival, make behaviour more predictable, avoid embarrassing situations, and express the values of the group.

Each group will create its own norms that might determine from the work performance to dress to making comments in a meeting. Groups exert pressure on members to force them to conform to the group’s standards and at times not to perform at higher levels. The norms often reflect the level of commitment, motivation, and performance of the group.

The majority of the group must agree that the norms are appropriate in order for the behaviour to be accepted. There must also be a shared understanding that the group supports the norms. It should be noted, however, that members might violate group norms from time to time.

If the majority of members do not adhere to the norms, then they will eventually change and will no longer serve as a standard for evaluating behaviour. Group members who do not conform to the norms will be punished by being excluded, ignored, or asked to leave the group.

Group Cohesiveness:

Cohesiveness refers to the bonding of group members or unity, feelings of attraction for each other and desire to remain part of the group. Many factors influence the amount of group cohesiveness – agreement on group goals, frequency of interaction, personal attractiveness, inter-group competition, favourable evaluation, etc.

The more difficult it is to obtain group membership the more cohesive the group will be. Groups also tend to become cohesive when they are in intense competition with other groups or face a serious external threat to survival. Smaller groups and those who spend considerable time together also tend to be more cohesive.

Cohesiveness in work groups has many positive effects, including worker satisfaction, low turnover and absenteeism, and higher productivity. However, highly cohesive groups may be detrimental to organizational performance if their goals are misaligned with organizational goals.

Highly cohesive groups may also be more vulnerable to groupthink. Groupthink occurs when members of a group exert pressure on each other to come to a consensus in decision making. Groupthink results in careless judgments, unrealistic appraisals of alternative courses of action, and a lack of reality testing.

Evidence suggests that groups typically outperform individuals when the tasks involved require a variety of skills, experience, and decision making. Groups are often more flexible and can quickly assemble, achieve goals, and disband or move on to another set of objectives.

Many organizations have found that groups have many motivational aspects as well. Group members are more likely to participate in decision-making and problem-solving activities leading to empowerment and increased productivity. Groups complete most of the work in an organization; thus, the effectiveness of the organization is limited by the effectiveness of its groups.

clip_image008

3. Group Processes:

Decision-making by a group is superior, because group generates more information and knowledge, generates diverse alternatives, increases acceptance of a solution, and increases legitimacy. But it is also true, that decision making is like ‘munde munde matirbhinna’.

Decisions take longer time, minority is dominated, pressure is applied to conform to group decisions, and none is responsible for the decisions. Group processes also include communication, conflict management, and leadership that we shall discuss in details in the chapters to follow hereafter.

Intergroup Relationships

Intergroup relations (relationships between different groups of people) range along a spectrum between tolerance and intolerance. The most tolerant form of intergroup relations is pluralism, in which no distinction is made between minority and majority groups, but instead there’s equal standing. At the other end of the continuum are amalgamation, expulsion, and even genocide—stark examples of intolerant intergroup relations.

Genocide

Genocide, the deliberate annihilation of a targeted (usually subordinate) group, is the most toxic intergroup relationship. Historically, we can see that genocide has included both the intent to exterminate a group and the function of exterminating of a group, intentional or not.

Possibly the most well-known case of genocide is Hitler’s attempt to exterminate the Jewish people in the first part of the twentieth century. Also known as the Holocaust, the explicit goal of Hitler’s “Final Solution” was the eradication of European Jewry, as well as the decimation of other minority groups such as Catholics, people with disabilities, and homosexuals. With forced emigration, concentration camps, and mass executions in gas chambers, Hitler’s Nazi regime was responsible for the deaths of 12 million people, 6 million of whom were Jewish. Hitler’s intent was clear, and the high Jewish death toll certainly indicates that Hitler and his regime committed genocide. But how do we understand genocide that is not so overt and deliberate?

genocide is not a just a historical concept; it is practiced today. Recently, ethnic and geographic conflicts in the Darfur region of Sudan have led to hundreds of thousands of deaths. As part of an ongoing land conflict, the Sudanese government and their state-sponsored Janjaweed militia have led a campaign of killing, forced displacement, and systematic rape of Darfuri people. Although a treaty was signed in 2011, the peace is fragile.

Segregation

Segregation refers to the physical separation of two groups, particularly in residence, but also in workplace and social functions. It is important to distinguish between de jure segregation (segregation that is enforced by law) and de facto segregation (segregation that occurs without laws but because of other factors). A stark example of de jure segregation is the apartheid movement of South Africa, which existed from 1948 to 1994. Under apartheid, black South Africans were stripped of their civil rights and forcibly relocated to areas that segregated them physically from their white compatriots. Only after decades of degradation, violent uprisings, and international advocacy was apartheid finally abolished.

Pluralism

Pluralism is represented by the ideal of the United States as a “salad bowl”: a great mixture of different cultures where each culture retains its own identity and yet adds to the flavor of the whole. True pluralism is characterized by mutual respect on the part of all cultures, both dominant and subordinate, creating a multicultural environment of acceptance. In reality, true pluralism is a difficult goal to reach. In the United States, the mutual respect required by pluralism is often missing, and the nation’s past pluralist model of a melting pot posits a society where cultural differences aren’t embraced as much as erased.

Assimilation

Assimilation describes the process by which a minority individual or group gives up its own identity by taking on the characteristics of the dominant culture. In the United States, which has a history of welcoming and absorbing immigrants from different lands, assimilation has been a function of immigration.

Amalgamation

Amalgamation is the process by which a minority group and a majority group combine to form a new group. Amalgamation creates the classic “melting pot” analogy; unlike the “salad bowl,” in which each culture retains its individuality, the “melting pot” ideal sees the combination of cultures that results in a new culture entirely.

What Is a Sense of Belonging?

The need to belong, also known as belongingness, refers to a human emotional need to affiliate with and be accepted by members of a group. This may include the need to belong to a peer group at school, to be accepted by co-workers, to be part of an athletic team, or to be part of a religious group.

A sense of belonging involves more than simply being acquainted with other people. It is centered on gaining acceptance, attention, and support from members of the group as well as providing the same attention to other members.

The need to belong to a group also can lead to changes in behaviors, beliefs, and attitudes as people strive to conform to the standards and norms of the group.

In social psychology, the need to belong is an intrinsic motivation to affiliate with others and be socially accepted.1 This need plays a role in a number of social phenomena such as self-presentation and social comparison.

Sense of Belonging in Action

What inspires people to seek out specific groups? In many cases, the need to belong to certain social groups results from sharing some point of commonality. For example, teens who share the same taste in clothing, music, and other interests might seek each other out to form friendships. Other factors that can lead individuals to seek out groups include:

  • Pop culture interests
  • Religious beliefs
  • Shared goals
  • Socioeconomic status

People often present themselves in a particular way in order to belong to a specific social group. For example, a new member of a high school sports team might adopt the dress and mannerisms of the other members of the team in order to fit in with the rest of the group.

People also spend a great deal of time comparing themselves to other members of the group in order to determine how well they fit in. This social comparison might lead an individual to adopt some of the same behaviors and attitudes of the most prominent members of the group in order to conform and gain greater acceptance.

Effect of Belongingness

Our need to belong is what drives us to seek out stable, long-lasting relationships with other people.2 It also motivates us to participate in social activities such as clubs, sports teams, religious groups, and community organizations.

In Abraham Maslow’s hierarchy of needs, belongingness is part of one of his major needs that motivate human behavior. The hierarchy is usually portrayed as a pyramid, with more basic needs at the base and more complex needs near the peak. The need for love and belonging lie at the center of the pyramid as part of the social needs.3

By belonging to a group, we feel as if we are a part of something bigger and more important than ourselves.

While Maslow suggested that these needs were less important than the physiological and safety needs, he believed that the need for belonging helped people to experience companionship and acceptance through family, friends, and other relationships.

A 2020 study in college students found a positive link between a sense of belonging and greater happiness and overall well-being, as well as an overall reduction in the mental health outcomes including:4

  • Anxiety
  • Depression
  • Hopelessness
  • Loneliness
  • Social anxiety
  • Suicidal thoughts5

Increase Your Sense of Belonging

There are steps you (or a loved one who is struggling) can take to increase sense of belonging.

  • Make an effort. Creating a sense of belonging takes effort, to put yourself out there, seek out activities and groups of people with whom you have common interests, and engage with others.
  • Be patient. It might take time to gain acceptance, attention, and support from members of the group.
  • Practice acceptance. Focus on the similarities, not the differences, that connect you to others, and remain open to new ways of thinking.

Aggression

REQUEST AN APPOINTMENT OR BOOK A CONSULANT – Sargam.dange.18@gmail.com

In psychology, the term aggression refers to a range of behaviors that can result in both physical and psychological harm to yourself, others, or objects in the environment. This type of behavior centers on harming another person either physically or mentally. It can be a sign of an underlying mental health disorder, a substance use disorder, or a medical disorder.

Aggressive behavior can cause physical or emotional harm to others. It may range from verbal abuse to physical abuse. It can also involve harming personal property.

Aggressive behavior violates social boundaries. It can lead to breakdowns in your relationships. It can be obvious or secretive. Occasional aggressive outbursts are common and even normal in the right circumstances. However, you should speak to your doctor if you experience aggressive behavior frequently or in patterns.

When you engage in aggressive behavior, you may feel irritable and restless. You may feel impulsive. You may find it hard to control your behavior. You might not know which behaviors are socially appropriate. In other cases, you might act aggressively on purpose. For example, you may use aggressive behavior to get revenge or provoke someone. You may also direct aggressive behavior towards yourself.

It’s important to understand the causes of your aggressive behavior. This can help you address it.

What Causes Aggressive Behavior?

Many things can shape your behavior. These can include your:

  • physical health
  • mental health
  • family structure
  • relationships with others
  • work or school environment
  • societal or socioeconomic factors
  • individual traits
  • life experiences

As an adult, you might act aggressively in response to negative experiences. For example, you might get aggressive when you feel frustrated. Your aggressive behavior may also be linked to depression, anxiety, PTSD, or other mental health conditions.

Health Causes of Aggressive Behavior

Many mental health conditions can contribute to aggressive behavior. For example, these conditions include:

  • autism spectrum disorder
  • attention deficit hyperactivity disorder (ADHD)
  • bipolar disorder
  • schizophrenia
  • conduct disorder
  • intermittent explosive disorder
  • post-traumatic stress disorder (PTSD)

Brain damage can also limit your ability to control aggression. You may experience brain damage as the result of:

  • stroke
  • head injury
  • certain infections
  • certain illnesses

Different health conditions contribute to aggression in different ways. For example, if you have autism or bipolar disorder, you might act aggressively when you feel frustrated or unable to speak about your feelings. If you have conduct disorder, you will act aggressively on purpose.

Forms of Aggression

Aggression can take a variety of forms, including:

  • Physical
  • Verbal
  • Mental
  • Emotional

While we often think of aggression as purely in physical forms such as hitting or pushing, psychological aggression can also be very damaging. Intimidating or verbally berating another person, for example, are examples of verbal, mental, and emotional aggression. How to Identify Emotional Abuse

Purposes of Aggression

Aggression can serve a number of different purposes, including:

  • To express anger or hostility
  • To assert dominance
  • To intimidate or threaten
  • To achieve a goal
  • To express possession
  • A response to fear
  • A reaction to pain
  • To compete with others

Types of Aggression

Psychologists distinguish between two different types of aggression:

  • Impulsive Aggression: Also known as affective aggression, impulsive aggression is characterized by strong emotions, usually anger. This form of aggression is not planned and often takes place in the heat of the moment. When another car cuts you off in traffic and you begin yelling and berating the other driver, you’re experiencing impulsive aggression. Research suggests that impulsive aggression, especially when it’s caused by anger, triggers the acute threat response system in the brain, involving the amygdala, hypothalamus, and periaqueductal gray (PAG).
  • Instrumental Aggression: Also known as predatory aggression, instrumental aggression is marked by behaviors that are intended to achieve a larger goal. Instrumental aggression is often carefully planned and usually exists as a means to an end. Hurting another person in a robbery or car-jacking is an example of this type of aggression. The aggressor’s goal is to obtain money or a vehicle, and harming another individual is the means to achieve that aim.

Factors That Can Influence Aggression

A number of different factors can influence the expression of aggression, including:

  • Biological Factors: Men are more likely than women to engage in physical aggression. While researchers have found that women are less likely to engage in physical aggression, they also suggest that women do use non-physical forms, such as verbal aggression, relational aggression, and social rejection.
  • Environmental Factors: How you were raised may play a role. People who grow up witnessing more forms of aggression are more likely to believe that such violence and hostility are socially acceptable. Bandura’s famous Bobo doll experiment demonstrated that observation can also play a role in how aggression is learned. Children who watched a video clip where an adult model behaved aggressively toward a Bobo doll were more likely to imitate those actions when given the opportunity.
  • Physical Factors: Epilepsy, dementia, psychosis, alcohol abuse, drug use, and brain injuries or abnormalities can also influence aggression.

Causes in Children

Aggression in children can be caused by several factors. These can include:

  • poor relationship skills
  • underlying health conditions
  • stress or frustration

Your child might imitate aggressive or violent behavior that they see in their daily life. They may receive attention for it from family members, teachers, or peers. You can accidentally encourage it by ignoring or rewarding their aggressive behavior.

Sometimes, children lash out due to fear or suspicion. This is more common if your child has schizophrenia, paranoia, or other forms of psychoses. If they have bipolar disorder, they might act aggressively during the manic phase of their condition. If they have depression, they might act aggressively when they feel irritated.

Your child might also act aggressively when they have trouble coping with their emotions. They might find it especially hard to deal with frustration. This is common in children who have autism spectrum disorder or cognitive impairments. If they become frustrated, they may be unable to fix or describe the situation causing their frustration. This can lead them to act out.

Children with ADHD or other disruptive disorders may show a lack of attention or understanding. They may also appear impulsive. In some cases, these behaviors may be considered aggressive. This is especially true in situations when their behaviors are socially unacceptable.

Causes in Teens

Aggressive behavior in teenagers is common. For example, many teens act rudely or get into arguments sometimes. However, your teen might have a problem with aggressive behavior if they regularly:

  • yell during arguments
  • get into fights
  • bully others

In some cases, they may act aggressively in response to:

  • stress
  • peer pressure
  • substance abuse
  • unhealthy relationships with family members or others

Puberty can also be a stressful time for many teens. If they don’t understand or know how to cope with changes during puberty, your teen may act aggressively. If they have a mental health condition, it can also contribute to aggressive behavior.

How Is Aggressive Behavior Treated?

To work through aggressive behavior, you need to identify its underlying causes.

It may help to talk to someone about experiences that make you feel aggressive. In some cases, you can learn how to avoid frustrating situations by making changes to your lifestyle or career. You can also develop strategies for coping with frustrating situations. For example, you can learn how to communicate more openly and honestly, without becoming aggressive.

Your doctor may recommend psychotherapy to help treat aggressive behavior. For example, cognitive behavioral therapy (CBT) can help you learn how to control your behavior. It can help you develop coping mechanisms. It can also help you understand the consequences of your actions. Talk therapy is another option. It can help you understand the causes of your aggression. It can also help you work through negative feelings.

In some cases, your doctor may prescribe medications to treat your aggressive behavior. For example, they may prescribe antiepileptic drugs (AEDs), such as phenytoin and carbamazepine. If you have schizophrenia, Alzheimer’s, or bipolar disorder, they may prescribe mood stabilizers. They may also encourage you to take omega-3 fatty acid supplements.

Your treatment plan will vary, depending on the underlying causes of your aggressive behavior. Speak with your doctor to learn more about your condition and treatment options.

Social Influence

REQUEST AN APPOINTMENT OR BOOK A CONSULANT – Sargam.dange.18@gmail.com

“Group behavior” refers to the ways people behave in large- or small-group situations. People join groups for a multitude of reasons, most frequently because membership satisfies a need of the individual. Group membership can provide companionship, survival and security, affiliation status, power and control, and achievement. There is currently no universal description of what constitutes a group, though research has identified a few common requirements that contribute to recognition of a group:

  • Interdependence—Individual members must depend, to some degree, on the output of the collective members.
  • Social interaction—Accomplishing a goal requires some form of verbal or nonverbal communication among members.
  • Perception of a group—All members of the collective must agree they are part of the group.
  • Commonality of purpose—All members of the collective come together to attain a common goal.
  • Favoritism—Members of the same group tend to be positively prejudiced toward other members and discriminate in their favor.

How Groups Influence Individual Behavior

Individual behavior and decision making can be influenced by the presence of others. There are both positive and negative implications of group influence on individual behavior. For example, group influence can often be useful in the context of work settings, team sports, and political activism. However, the influence of groups on the individual can also generate negative behaviors.

While there are many ways a group can influence behavior, we will focus on three key phenomena: groupthink, groupshift, and deindividuation. Groupthink happens when group members, faced with an important choice, become so focused on making a smooth, quick decision that they overlook other, possibly more fruitful options. Groupshift is a phenomenon in which the initial positions of individual members of a group are exaggerated toward a more extreme position. Deindividuation happens when a person lets go of self-consciousness and control and does what the group is doing, usually with negative goals or outcomes. We will discuss these more in detail below.

Groupshift

Groupshift is the phenomenon in which the initial positions of individual members of a group are exaggerated toward a more extreme position. When people are in groups, they assess risk differently than they do when they are alone. In the group, they are likely to make riskier decisions as the shared risk makes the individual risk seem to be less.

What appears to happen in groups is that discussion leads to a significant shift in the position of the members to a more extreme position in the direction they were all already leaning. A group of moderate liberals may shift from moderate to strongly liberal views when in a group together. A group of mildly racist people may become viciously racist when together. The theory behind this shift is that the group dynamic allows the individual members to feel that their position is correct or supported, and they will feel more comfortable taking on more extreme views, as other members of the group support their initial ideas. The extreme ideas seem less risky as it appears the view is held by numerous like-minded people.

Deindividuation

Deindividuation is exactly what the word implies: a loss of one’s individuality. Instead of acting as individuals, people experiencing deindividuation become lost in a group. This often means that they will go along with whatever the group is doing, whether it be rioting, looting, lynching, or engaging in cyberbullying. Some people posit that this happens because individuals experience a sense of anonymity in a group. The larger the group, the higher the incidence of deindividuation, which is characterized by an individual relinquishing self-consciousness and control and doing what the group is doing. This occurs when people are moved by the group experience to do things that, without the group for support, they would not normally do.

It is important to distinguish deindividuation from obedience (when a person yields to explicit instructions or orders from an authority figure), compliance (when a person responds favorably to a request from others) and conformity (when a person attempts to match his attitudes to group norms, versus the total relinquishing of individuality seen in deindividuation).

Obedience

Obedience is a form of social influence that occurs when a person yields to explicit instructions or orders from an authority figure.

Groupthink

Groupthink is a psychological phenomenon that occurs within a group of people, in which the desire for harmony or conformity in the group results in an incorrect or deviant decision-making outcome. It has been further defined as a mode of thinking that people engage in when they are deeply involved in a cohesive group, when the members’ strivings for unanimity override their motivation to realistically appraise alternative courses of action.

Group members try to minimize conflict and reach a consensus decision without critical evaluation of alternative ideas or viewpoints. Several conditions must take place for groupthink to occur: the group must be isolated from outside influences;  loyalty must prevent individuals from raising controversial issues of alternative solutions; there must be a loss of individual creativity and independent thinking; and the group must experience the “illusion of invulnerability,” an inflated certainty that the right decision has been made. Typically the group is under a high level of pressure to make a decision, and it lacks an impartial leader. These factors can lead a group to make a catastrophically bad decision. Nazi Germany is often cited as a prime example of the negative potential of groupthink because a number of factors, such as shared illusions and rationalizations and a lack of individual accountability, allowed for a few powerful leaders to enlist many otherwise “normal” people in committing mass acts of violence.

While groupthink is generally accepted as a negative phenomenon, it has been proposed that groups with a strong ability to work together are able to solve problems more efficiently than individuals or less cohesive groups.

Normative social influence

A second type of conformity is normative social influence. People want to ‘fit in’ amongst friends and colleagues, and to be liked and respected by other members of their social group. They value the opinions of other members, and seek to maintain their standing within the group. Therefore, individuals will adjust their own attitudes and behavior to match the accepted norms of the group.

This conformity with the majority may involve following the fashion trends that are popular amongst a group of friends, adopting the rituals of a religious group or watching a particular TV show because classmates at college talk about it.

Social influence and conformity

Social influence takes a number of forms. One type of such influence is conformity, when a person adopts the opinions or behaviors of others. This often occurs in groups, when an individual conforms to the social norms respected by a majority of the group’s members.

An individual may conform to the opinions and values of a group. They express support for views accepted by the group and will withhold criticism of group norms. Behavioral conformity can also influence a group member’s actions: a person will behave in a way that is similar to others in the group.

Public-versus-private conformity

When conforming to the social norms of a group, a person may disagree with the opinions that they express or the actions that they take, but nonetheless, they adopt the behavior that is expected of them.

  • Public conformity involves matching one’s behavior meet the expectations of others, whilst privately holding a different view. For example, a student may express a liking for a rock band because all of his friends listen to it. Privately, however, he may dislike their music, but conforms in front of his friends to gain their acceptance.
  • Private conformity occurs when a person internalizes the views of a group, and adopts a majority opinion as his or her own. For instance, the student listens to the music of a rock band that his friends like. Over time, he realises that he too enjoys this type of music. As his private opinion has changed, private conformity has occurred

Nature of intergroup relations

REQUEST AN APPOINTMENT OR BOOK A CONSULANT – Sargam.dange.18@gmail.com

Intergroup relations involve the feelings, evaluations, beliefs, and behaviors that groups and their members have toward another group and its members. Negative intergroup relations typically involve prejudice (negative feelings and evaluations), stereotypes (beliefs about groups and their members), and discrimination (unfair treatment). However, intergroup bias does not necessarily require negative orientations. Bias may reflect unusually favorable attitudes and beliefs about members of one’s own group and preferential treatment toward them. The nature of intergroup relations is determined by psychological processes associated with social categorization, by the personalities and motivations of group members, and by the functional relationship between the groups. These processes apply to a wide range of groups, including work teams, divisions within an organization, companies, and countries.

Genocide

Genocide, the deliberate annihilation of a targeted (usually subordinate) group, is the most toxic intergroup relationship. Historically, we can see that genocide has included both the intent to exterminate a group and the function of exterminating of a group, intentional or not.

Possibly the most well-known case of genocide is Hitler’s attempt to exterminate the Jewish people in the first part of the twentieth century. Also known as the Holocaust, the explicit goal of Hitler’s “Final Solution” was the eradication of European Jewry, as well as the decimation of other minority groups such as Catholics, people with disabilities, and homosexuals. With forced emigration, concentration camps, and mass executions in gas chambers, Hitler’s Nazi regime was responsible for the deaths of 12 million people, 6 million of whom were Jewish. Hitler’s intent was clear, and the high Jewish death toll certainly indicates that Hitler and his regime committed genocide. But how do we understand genocide that is not so overt and deliberate?

The treatment of aboriginal Australians is also an example of genocide committed against indigenous people. Historical accounts suggest that between 1824 and 1908, white settlers killed more than 10,000 native aborigines in Tasmania and Australia (Tatz 2006). Another example is the European colonization of North America. Some historians estimate that Native American populations dwindled from approximately 12 million people in the year 1500 to barely 237,000 by the year 1900 (Lewy 2004). European settlers coerced American Indians off their own lands, often causing thousands of deaths in forced removals, such as occurred in the Cherokee or Potawatomi Trail of Tears. Settlers also enslaved Native Americans and forced them to give up their religious and cultural practices. But the major cause of Native American death was neither slavery nor war nor forced removal: it was the introduction of European diseases and Indians’ lack of immunity to them. Smallpox, diphtheria, and measles flourished among indigenous American tribes who had no exposure to the diseases and no ability to fight them. Quite simply, these diseases decimated the tribes. How planned this genocide was remains a topic of contention. Some argue that the spread of disease was an unintended effect of conquest, while others believe it was intentional citing rumors of smallpox-infected blankets being distributed as “gifts” to tribes.

Genocide is not a just a historical concept; it is practiced today. Recently, ethnic and geographic conflicts in the Darfur region of Sudan have led to hundreds of thousands of deaths. As part of an ongoing land conflict, the Sudanese government and their state-sponsored Janjaweed militia have led a campaign of killing, forced displacement, and systematic rape of Darfuri people. Although a treaty was signed in 2011, the peace is fragile.

Expulsion

Expulsion refers to a subordinate group being forced, by a dominant group, to leave a certain area or country. As seen in the examples of the Trail of Tears and the Holocaust, expulsion can be a factor in genocide. However, it can also stand on its own as a destructive group interaction. Expulsion has often occurred historically with an ethnic or racial basis. In the United States, President Franklin D. Roosevelt issued Executive Order 9066 in 1942, after the Japanese government’s attack on Pearl Harbor. The Order authorized the establishment of internment camps for anyone with as little as one-eighth Japanese ancestry (i.e., one great-grandparent who was Japanese). Over 120,000 legal Japanese residents and Japanese U.S. citizens, many of them children, were held in these camps for up to four years, despite the fact that there was never any evidence of collusion or espionage. (In fact, many Japanese Americans continued to demonstrate their loyalty to the United States by serving in the U.S. military during the War.) In the 1990s, the U.S. executive branch issued a formal apology for this expulsion; reparation efforts continue today.

Segregation

Segregation refers to the physical separation of two groups, particularly in residence, but also in workplace and social functions. It is important to distinguish between de jure segregation (segregation that is enforced by law) and de facto segregation (segregation that occurs without laws but because of other factors). A stark example of de jure segregation is the apartheid movement of South Africa, which existed from 1948 to 1994. Under apartheid, black South Africans were stripped of their civil rights and forcibly relocated to areas that segregated them physically from their white compatriots. Only after decades of degradation, violent uprisings, and international advocacy was apartheid finally abolished.

Pluralism

Pluralism is represented by the ideal of the United States as a “salad bowl”: a great mixture of different cultures where each culture retains its own identity and yet adds to the flavor of the whole. True pluralism is characterized by mutual respect on the part of all cultures, both dominant and subordinate, creating a multicultural environment of acceptance. In reality, true pluralism is a difficult goal to reach. In the United States, the mutual respect required by pluralism is often missing, and the nation’s past pluralist model of a melting pot posits a society where cultural differences aren’t embraced as much as erased.

Assimilation

Assimilation describes the process by which a minority individual or group gives up its own identity by taking on the characteristics of the dominant culture. In the United States, which has a history of welcoming and absorbing immigrants from different lands, assimilation has been a function of immigration.

For many immigrants to the United States, the Statue of Liberty is a symbol of freedom and a new life. Unfortunately, they often encounter prejudice and discrimination. (Photo courtesy of Mark Heard/flickr)

Most people in the United States have immigrant ancestors. In relatively recent history, between 1890 and 1920, the United States became home to around 24 million immigrants. In the decades since then, further waves of immigrants have come to these shores and have eventually been absorbed into U.S. culture, sometimes after facing extended periods of prejudice and discrimination. Assimilation may lead to the loss of the minority group’s cultural identity as they become absorbed into the dominant culture, but assimilation has minimal to no impact on the majority group’s cultural identity.

Amalgamation

Amalgamation is the process by which a minority group and a majority group combine to form a new group. Amalgamation creates the classic “melting pot” analogy; unlike the “salad bowl,” in which each culture retains its individuality, the “melting pot” ideal sees the combination of cultures that results in a new culture entirely.

Amalgamation, also known as miscegenation, is achieved through intermarriage between races. In the United States, antimiscegenation laws flourished in the South during the Jim Crow era. It wasn’t until 1967’s Loving v. Virginia that the last antimiscegenation law was struck from the books, making these laws unconstitutional.

Severe Acute Respiratory Syndrome (SARS)

REQUEST AN APPOINTMENT OR BOOK A CONSULANT – Sargam.dange.18@gmail.com

Severe acute respiratory syndrome (SARS) is a viral respiratory disease caused by a SARS-associated coronavirus. It was first identified at the end of February 2003 during an outbreak that emerged in China and spread to 4 other countries. WHO co-ordinated the international investigation with the assistance of the Global Outbreak Alert and Response Network (GOARN) and worked closely with health authorities in affected countries to provide epidemiological, clinical and logistical support and to bring the outbreak under control.

SARS is an airborne virus and can spread through small droplets of saliva in a similar way to the cold and influenza. It was the first severe and readily transmissible new disease to emerge in the 21st century and showed a clear capacity to spread along the routes of international air travel.

SARS can also be spread indirectly via surfaces that have been touched by someone who is infected with the virus.

Most patients identified with SARS were previously healthy adults aged 25–70 years. A few suspected cases of SARS have been reported among children under 15 years. The case fatality among persons with illness meeting the current WHO case definition for probable and suspected cases of SARS is around 3%.

Causes

SARS is caused by a strain of coronavirus, the same family of viruses that causes the common cold. Previously, these viruses had never been particularly dangerous to humans.

Coronaviruses can, however, cause severe disease in animals, and that’s why scientists suspected that the SARS virus might have crossed from animals to humans. It now seems likely that that the virus evolved from one or more animal viruses into a new strain.

Risk factors

In general, people at greatest risk of SARS are those who have had direct, close contact with someone who’s infected, such as family members and health care workers.

Complications

Many people with SARS develop pneumonia, and breathing problems can become so severe that a mechanical respirator is needed. SARS is fatal in some cases, often due to respiratory failure. Other possible complications include heart and liver failure.

People older than 60 — especially those with underlying conditions such as diabetes or hepatitis — are at the highest risk of serious complications.

What Are the Symptoms of SARS?

SARS symptoms are similar to those of the flu, including:

  • fever over 100.4°F
  • dry cough
  • sore throat
  • problems breathing, including shortness of breath
  • headache
  • body aches
  • loss of appetite
  • malaise
  • night sweats and chills
  • confusion
  • rash
  • diarrhea

Breathing issues will appear within two to 10 days after a person is exposed to the virus. Health officials will quarantine a person who presents the above symptoms and family members if they have a history of foreign travel. The person will be quarantined for 10 days to prevent the virus from spreading.

Factors that increase your risk of contracting the disease include close contact with someone diagnosed with SARS and a history of travel to any other country with a reported SARS outbreak.

REQUEST AN APPOINTMENT OR BOOK A CONSULANT – Sargam.dange.18@gmail.com

How Is SARS Spread?

SARS can spread when an infected person sneezes, coughs, or comes into face-to-face contact with someone else. Face-to-face contact refers to:

  • caring for someone with SARS
  • having contact with the bodily fluids of a person with SARS
  • kissing, hugging, touching, or sharing eating or drinking utensils with an infected person

You can also contract SARS by touching a surface contaminated with respiratory droplets from an infected person and then touching your eyes, mouth, or nose. The disease may also be spread through the air, but researchers have not confirmed this.

How Is SARS Diagnosed?

Various lab tests have been developed to detect the SARS virus. During the first outbreak of SARS, there were no laboratory tests for the disease. Diagnosis was made primarily through symptoms and medical history. Now, laboratory tests can be performed on nasal and throat swabs or blood samples. A chest X-ray or CT scan may also reveal signs of pneumonia characteristic of SARS.

Can SARS Cause Complications?

Most of the fatalities associated with SARS result from respiratory failure. SARS can also lead to heart and liver failure. The group most at risk of developing complications is people over 60 who have been diagnosed with another chronic condition.

How Can SARS Be Treated?

There is no confirmed treatment that works for every person who has SARS. Antiviral medications and steroids are sometimes given to reduce lung swelling, but aren’t effective for everyone.

Supplemental oxygen or a ventilator may be prescribed if necessary. In severe cases, blood plasma from someone who has already recovered from SARS may also be administered. However, there is not yet enough evidence to prove that these treatments are effective.

Prevention

Researchers are working on several types of vaccines for SARS, but none has been tested in humans. If SARS infections reappear, follow these safety guidelines if you’re caring for someone who may have a SARS infection:

  • Wash your hands. Clean your hands frequently with soap and hot water or use an alcohol-based hand rub containing at least 60% alcohol.
  • Wear disposable gloves. If you have contact with the person’s body fluids or feces, wear disposable gloves. Throw the gloves away immediately after use and wash your hands thoroughly.
  • Wear a surgical mask. When you’re in the same room as a person with SARS, cover your mouth and nose with a surgical mask. Wearing eyeglasses also may offer some protection.
  • Wash personal items. Use soap and hot water to wash the utensils, towels, bedding and clothing of someone with SARS.
  • Disinfect surfaces. Use a household disinfectant to clean any surfaces that may have been contaminated with sweat, saliva, mucus, vomit, stool or urine. Wear disposable gloves while you clean and throw the gloves away when you’re done.

Follow all precautions for at least 10 days after the person’s signs and symptoms have disappeared. Keep children home from school if they develop a fever or respiratory symptoms within 10 days of being exposed to someone with SARS

What Is the Outlook for SARS?

Researchers are currently working on a vaccine for SARS, but there have been no human trials for any potential vaccine. Because there’s no confirmed treatment or cure for SARS, it’s important to take as many preventive measures as possible.

Here are some of the best ways to prevent transmission of SARS if you’re in close contact with someone who’s been diagnosed with the disease:

  • Wash your hands frequently.
  • Wear disposable gloves if touching any infected bodily fluids.
  • Wear a surgical mask when in the same room with a person with SARS.
  • Disinfect surfaces that may have been contaminated with the virus.
  • Wash all personal items, including bedding and utensils, used by a person with SARS.

Moreover, follow all of the above steps for at least 10 days after the symptoms of SARS have gone away. Keep children home from school if they develop a fever or any breathing problems after coming in contact with someone with SARS.

Mucormycosis (zygomycosis)

REQUEST AN APPOINTMENT OR BOOK A CONSULANT – Sargam.dange.18@gmail.com

Mucormycosis (previously called zygomycosis) is a serious but rare fungal infection caused by a group of molds called mucormycetes. These molds live throughout the environment. Mucormycosis mainly affects people who have health problems or take medicines that lower the body’s ability to fight germs and sickness. It most commonly affects the sinuses or the lungs after inhaling fungal spores from the air. It can also occur on the skin after a cut, burn, or other type of skin injury.

What is mucormycosis?

  • Mucormycosis is the general term that indicates any fungal infection caused by various genera of the class Zygomycetes.
  • Another term used in medical and lay publications that means the same is phycomycosis.
  • Mucormycosis can result in an acute, rapidly advancing, and occasionally fatal disease caused by different fungi commonly found in the soil or environment. These fungal infections are diagnosed relatively infrequently; however, they occur in individual people who are debilitated in some major way (uncontrolled diabetics, immunocompromised patients) and occasionally in groups of people that are injured (often multiple injuries and penetrating injuries that are contaminated with soil and water from the environment).
  • Such groups of people are those that are injured in disasters such as tsunamis, hurricanes, earthquakes or tornadoes, where otherwise healthy people can have contaminated soil and water inhaled, embedded in wounds, or simply forced into skin, mouth, eyes, and nose by the force of water, soil, or wind pressure. The disease is not passed person to person.
  • A cluster of mucormycosis infections occurred in people who initially survived devastating tornadoes which struck Joplin, Missouri, on May 23, 2011. Thirteen cases were confirmed, all in persons with severe wounds, including fractures, multiple wounds, penetrating injuries, and blunt trauma. Ten patients required intensive care and five died.
  • Because the majority of mucormycosis infections are caused by one family member in the class of Zygomycetes (family member Mucoraceae), many clinicians now term the disease mucormycosis instead of zygomycosis, the more “general” term.
  • The lay press has used terms like “Black Death” and “Zombie disease” to describe this fungal infection but such terms seldom help people to understand this disease.
  • Such terms may cause misunderstandings between the patients, their families, and the public; many clinicians think these potentially harmful or cruel terms should not be used by responsible individuals.

causes

Zygomycetes represent the general class of fungi that cause mucormycosis. Rhizopus arrhizus species from the Mucoraceae family are the most commonly identified cause of mucormycosis in humans. Other fungal causes may include Mucor species, Cunninghamella Bertholletia, Apophysomyces elegans, Absidia species, Saksenaea species, Rhizomucor pusillus, Entomophthora species, Conidiobolus species, and Basidiobolus species.

  • Mucoraceae are found worldwide and in the ecosystem are responsible for initiating and decaying most organic material in the environment.
  • Most fungi are identified by their unique morphological appearance viewed microscopically and determined by a professional practicing in fungal identification (microbiologist or pathologist).
Picture of sporangia of a Mucor spp. fungus

Picture of sporangia of a Mucor spp. fungus

  • In general, mucormycosis is an infection not often seen by many doctors because the fungal causes are not readily infectious.
  • Usually, an infection develops because of some unusual circumstance that places the fungi in contact with compromised or injured animal or human tissue.
  • However, once established, the fungi can rapidly multiply in blood vessel walls where it effectively reduces and cuts off blood to tissues, thereby creating its own decaying organic food source resulting in widespread tissue destruction.
  • If this fulminant spread of fungi is not stopped, death is the outcome.

mucormycosis symptoms and signs

Most symptoms of mucormycosis do not differ to any major extent between the various fungal causes.

Most authorities describe the signs and symptoms of the disease according to the predominant or initial body area that is infected. Some patients have more than one body area infected.

The following is a list of signs and symptoms (note that many authors prefer the term mucormycosis instead of zygomycosis since the majority of fungi when identified, are from the Mucoraceae family of fungi):

  • Rhinocerebral mucormycosis: fever, headache, reddish and swollen skin over nose and sinuses, dark scabbing in the nose by the eye(s), visual problems, eye(s) swelling, facial pain
  • Pulmonary (lung) mucormycosis: fever, coughing sometimes with bloody or dark fluid production, shortness of breath
  • GI mucormycosis: diffuse abdominal pain, bloody and sometimes dark vomitus, abdominal distension
  • Renal mucormycosis: fever, flank pain
  • Cutaneous mucormycosis: initially, reddish and swollen skin often adjacent to an area of skin trauma, that becomes an ulcer with a dark center and sharply defined edges
  • Disseminated mucormycosis: initially may have any of the above symptoms; as the disease spreads to other organs, headaches, fever, and mental status changes occur

Although these symptoms suggest that a patient may have mucormycosis, they are not definitive. In addition, they may not develop very quickly because it may take a few days to over a week in many people before the symptoms develop.

When they do initially develop, it is not unusual to describe the symptoms to causes other than fungi (often to secondary bacterial infections). Consequently, the fungal diagnosis may be delayed.

How do medical professionals diagnose mucormycosis?

  • Presumptive diagnosis is based on the patient’s history, physical exam, and the patient’s risk factors for getting a fungal infection. A definitive diagnosis is difficult.
  • Although tests such as CT or MRI may help define the extent of infections or tissue destruction, their findings are not specific for mucormycosis.
  • There are no serological or blood tests that are helpful. Growth of the fungi from a biopsy (tissue obtained by surgical removal or endoscopes with biopsy tool) of infected tissue, accompanied by special tissue stains looking for unique structural components, may identify the fungus and help make the definitive diagnosis. This helps distinguish mucormycosis from other fungal diseases such as candidiasis and histoplasmosis.
  • However, it is still sometimes difficult to determine the specific fungal genus and species infecting the patient.
  • Consequently, mucormycosis is often a “working” diagnosis that clinicians use because the supportive care and treatments for the causative fungal agents are essentially the same.

risk factors for mucormycosis

  • A risk factor for mucormycosis includes any debilitating disease process, especially diseases that can yield compromised blood flow to tissue.
  • The classic example is the patient with uncontrolled diabetes and foot ulcers where dirt or debris can easily reach compromised tissue.
  • Patients with burns, malignancies, immunocompromised patients, patients with a splenectomy, and people with wounds (usually severe) that have been contaminated with soil or environmental water are at higher risk to get mucormycosis.
  • Consequently, people injured in environmental disasters are, as a group, at high risk for this infection.

treatment of mucormycosis

  • Treatments for mucormycosis need to be fast and aggressive. The need for speed is because by the time even the presumptive diagnosis is made, often the patient has suffered significant tissue damage that cannot be reversed.
  • Most patients will require both surgical and medical treatments.
  • Most infectious-disease experts say that without aggressive surgical debridement of the infected area, the patient is likely to die.
  • Medications play an important role. Two main goals are sought at the same time: antifungal medications to slow or halt fungal spread and medications to treat any debilitating underlying diseases.
    • Amphotericin B (initially intravenous) is the usual drug of choice for antifungal treatment.
    • In addition, posaconazole or isavuconazole may treat mucormycosis.
  • Patients with underlying diseases like diabetes need their diabetes optimally controlled.
  • Patients normally on steroids or undergoing treatment with deferoxamine (Desferal; used to remove excess iron in the body) are likely to have these medications stopped because they can increase the survival of fungi in the body.
  • Patients may need additional surgeries and usually need antifungal therapy for an extended time period (weeks to months) depending on the severity of the disease.
  • Consultation with an infectious-disease expert is advised.

prognosis of mucormycosis

  • The prognosis of mucormycosis is usually fair to poor; the prognosis depends on the overall health of the patient, the speed of diagnosis and treatment, the patient’s ability to respond to treatments, the complete debridement of the infected body area, and the body area that is initially infected.
  • For example, the mortality (death rate) of patients with rhinocerebral and GI mucormycosis is about 85% while the mortality rate for all patients with other types of mucormycosis is about 50%.
  • Patients who survive this dangerous infection often have disabilities related to the extent of tissue lost due to the fungal destruction and the necessary surgical debridement (blindness, limb loss, organ dysfunctions).

Is it possible to prevent mucormycosis?

  • Avoiding predicted disasters (hurricanes) and taking safety measures if possible (getting to safe shelters if warning of a tsunami, tornado, or earthquake) are probably the best ways to avoid mucormycosis.
  • Patients with debilitating disease can increase their likelihood of avoiding the infection by good control (treatment) of their health problem with diabetes as the classic example.
  • Some clinicians suggest that if a patient is exposed to circumstances that are favorable for mucormycosis to develop, if they are taking prednisone (Deltasone, Orasone, Prednicen-M, Liquid Pred) or deferoxamine (Desferal), they should cease these medications (consult your doctor or emergency center if possible before modifiying medications).
  • Finally, if a person thinks they may have mucormycosis, they should consult their doctor or an emergency center immediately.
  • There is no vaccine available for mucormycosis.

What research is being done on mucormycosis?

Unfortunately, very little research is being done on this disease. Most studies available discuss the two major factors.

  • First is the data showing the increasing incidence noted in patients with debilitating diseases, currently with a focus on those who are immunocompromised by diseases or by medical treatment.
  • Second are studies comparing treatment plans of surgery combined with antifungal medication.
  • Currently, surgery and amphotericin B still seem to be the treatments that give the best results.
  • As the incidence and recognition of zygomycosis (mucormycosis) increases, more research may be done.
