Literary descriptions of shyness can be traced back to the days of

[[Hippocrates]] around 400 B.C. Hippocrates described someone who 'through bashfulness, suspicion, and timorousness, will not be seen abroad; loves darkness as life and cannot endure the light or to sit in lightsome places; his hat still in his eyes, he will neither see, nor be seen by his good will. He dare not come in company for fear he should be misused, disgraced, overshoot himself in gesture or speeches, or be sick; he thinks every man observes him'.

Retrieved February 21, 2006.</ref> For one to be socially phobic, exposure
to the feared situation must provoke [[anxiety]] and the person must
recognize this anxiety as irrational (although this may be absent in
children). If another disorder is present, the social phobic fear is
unrelated to it. For instance, if a person has a history of panic
attacks,
having a panic attack must not be the sufferer's fear. Sufferers are
typically more self-conscious and self-attentive than others. <ref

tend to limit or remove themselves from situations where they may be
subject to evaluation. Sufferers often recognize their fear is excessive
or irrational, yet can't seem to break out of the cycle. As such, the
diagnosis of social phobia is made only when the fear leads to avoiding
occupational functions, social activities, or relationships with others.<ref name="crozier-cycle">Crozier, page 242.</ref>

between shyness and social phobia. Both share several features: negative
[[cognition]]s in social situations, heightened
[[physiology|physiological]] reactivity, a tendency to avoid social
situations, and deficits in social skills. Negative cognitions include
fear of negative evaluation, self-consciousness, devaluation of
social
skills, self-deprecating thoughts, and self-blaming attributions for
social
difficulties. Social phobia is distinct from shyness in that it has a
lower
prevalence in the population, follows a more chronic course, is more
functionally debilitating, and has a later age of onset. There are
problems with these kinds of comparisons. It may be that the differences
between them are quantitative rather than qualitative.<ref

Social phobia should not be confused with [[panic disorder]]. Sufferers
of
panic disorder are sometimes convinced that their panic comes from some dire
physical
cause, and often go to the hospital or call for an ambulance during or
after their attacks. Social phobics may experience a panic attack when
triggered, but they are aware that it is extreme anxiety they are
experiencing, and that the cause is an irrational fear. Few social
phobics would willingly go to a hospital in that instance because they
fear rejection and judgment by authority figures (such as the medical
staff). The general form of social anxiety is sometimes incorrectly
called
[[generalized anxiety disorder]]. The principal difference between the
two
is that the social phobia deals with anxiety in a social setting, while
generalized anxiety disorder is extreme anxiety for any situation (work,
school, ''et al.''), not necessarily one involving other people.
 
==Symptoms==
 
===Cognitive aspects===
In [[cognitive model]]s of Social Anxiety Disorder, social phobics experience
dread over how they will be presented to others. They may be overly
self-conscious, pay high self-attention after the activity, or have high
performance standards for themselves. According to the [[social psychology]]
theory of self-presentation, a sufferer
attempts
to create a well-mannered impression on others but believes he or she is
unable to do so. Many times, prior to the potentially anxiety-provoking
social situation, sufferers may deliberate over what could go wrong and
how to deal with each unexpected case. <!--example-->
After the event, they may have the [[perception]] they performed
unsatisfactorily. Consequently, they will review anything that may have
possibly been abnormal or embarrassing. These thoughts do not just
terminate soon after the encounter, but may extend for weeks or
longer.<ref name="fears">Shyness & Social Anxiety Treatment Australia
[http://www.socialanxietyassist.com.au/common_fears.shtml Social Phobia]</ref> Those with social phobia tend to interpret neutral or
ambiguous conversations with a negative outlook and although still
inconclusive, some studies suggest that socially anxious individuals
remember more negative memories than those less distressed.<ref

21, 2006.</ref> An example of an instance may be that of an employee
presenting to his co-workers. During the presentation, the person may
[[stutter]] a word upon which he or she may worry that other people
significantly noticed and think that he or she is a terrible presenter.
This cognitive thought propels further anxiety which may lead to further
stuttering, sweating and a possible panic attack.
Recent studies have also shown that a subject with social anxiety might find their average peers to be ignorant, immoral, shallow, and/or mean. A "blank mind" defect can also be observed in many subjects, although research on this topic is still under way.
 
===Behavioral aspects===
Social anxiety disorder is a persistent fear of one or more situations in
which the person is exposed to possible scrutiny by others and fears that
he or she may do something or act in a way that will be humiliating or
embarrassing. It exceeds normal "shyness" as it leads to excessive
social avoidance and substantial social or occupational impairment.
Feared activities may include almost any type of social interaction,
especially small groups, dating, parties, talking to strangers,
restaurants, etc. Physical symptoms include "mind going blank", fast
heartbeat, blushing, [[stomach ache]]. Cognitive distortions are a hallmark,
and learned about in CBT (cognitive-behavioral therapy). Thoughts are
often self-defeating and inaccurate.

somebody and answering the phone. It may appear early in childhood.
 
According to psychologist [[B.F. Skinner]], [[phobias]] are controlled by
escape and [[avoidance response|avoidance
behaviors]].
For instance, a student may leave the room when talking in front of the
class (escape) and refrain from doing verbal presentations because of the
previously encountered anxiety attack (avoid). Minor avoidance behaviors
are exposed when a person avoids [[eye contact]] and crosses arms to avoid
recognizable [[Tremor|shaking]].<ref name="furmark" /> A [[fight-or-flight response]]
is then triggered in such events. Preventing these automatic responses is
at the core of treatment for social anxiety.
 
===Physiological aspects===
Physiological effects, similar to those in other anxiety disorders, are
present in social phobics. Faced with an uncomfortable situation,
children
with social anxiety may display [[tantrum]]s, [[weeping]], clinging
to parents, and shutting themselves out.<ref name="physiology">eNotes.

disturbance may appear,
especially when passing a group of people. [[Blush]]ing is commonly
exhibited by individuals suffering from social phobia.<ref name="furmark"/> These visible symptoms further reinforce the anxiety in the presence
of
others. A 2006 study found that the area of the [[brain]] called the
[[amygdala]], part of the [[limbic system]], is [[hyperactive]] when
patients are shown threatening faces or confronted with frightening
situations. They found that patients with more severe social phobia
showed
a [[correlation]] with the increased response in the
amygdala.<ref>[http://www.sciencedaily.com/releases/2006/01/060118205940.htm Studying Brain Activity Could Aid Diagnosis Of Social Phobia]. Monash

When [[prevalence]] estimates were based on the examination of [[psychiatric]]
clinic samples, social anxiety disorder was thought to be a relatively
rare disorder. The opposite was instead true; social anxiety was common
but many were afraid to seek psychiatric help, leading to an
understatement of the problem.<ref name="furmark" /> Prevalence rates
vary
widely because of its vague diagnostic criteria and its overlapping
symptoms with other disorders. There has been some debate on how the
studies are conducted and whether the illness truly impairs the
respondents as laid out in the official criteria. Psychologist [[Dr. Ray Crozier]] argues, "it is difficult to ascertain whether the person being
interviewed adheres to the DSM-III-R criteria or whether they are merely
exhibiting poor [[social skills]] or shyness."<ref

The [[National Comorbidity Study|National Comorbidity Survey]] of over
8,000 American correspondents in 1994 revealed a 12-month and lifetime
prevalence rates of 7.9 percent and 13.3 percent making it the third most prevalent
psychiatric disorder after depression and alcohol dependence and the most
apparent of the anxiety
disorders.<ref>[http://www.findarticles.com/p/articles/mi_m3225/is_8_60/ai_58266993 Social Anxiety Disorder: A Common, Underrecognized Mental Disorder].

==Comorbidity==
There is a high degree of [[comorbidity]] with other psychiatric
disorders. Social phobia often occurs alongside low [[self-esteem]] and
[[clinical depression]], due to lack of personal relationships and long
periods of isolation from avoiding social situations. To try to reduce
their anxiety and alleviate depression, people with social phobia may use
alcohol or other drugs, which can lead to [[substance abuse]]. It is
estimated that one-fifth of patients with social anxiety disorder also
suffer from alcohol dependence.<ref name="sa-alcohol">Alcohol Research

the most common disorders diagnosed in patients with social phobia are

correlated with social phobia.<ref name="crozier-correlation">Crozier,
page 361.</ref> Because of its close relationship and overlapping

with other illnesses, treating social phobics may help understand

There is research indicating that social anxiety disorder is often correlated with [[bipolar disorder]] [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=16630705&query_hl=5&itool=pubmed_docsum].

When [[prevalence]] estimates were based on the examination of [[psychiatric]]
clinic samples, social anxiety disorder was thought to be a relatively
rare disorder. The opposite was instead true; social anxiety was common
but many were afraid to seek psychiatric help, leading to an
understatement of the problem.<ref name="furmark" /> Prevalence rates
vary
widely because of its vague diagnostic criteria and its overlapping
symptoms with other disorders. There has been some debate on how the
studies are conducted and whether the illness truly impairs the
respondents as laid out in the official criteria. Psychologist Dr. Ray Crozier argues, "it is difficult to ascertain whether the person being
interviewed adheres to the DSM-III-R criteria or whether they are merely
exhibiting poor [[social skills]] or shyness."<ref

psychiatric disorder after depression and alcohol dependence and the most
apparent of the anxiety
disorders.<ref>[http://www.findarticles.com/p/articles/mi_m3225/is_8_60/ai_58266993 Social Anxiety Disorder: A Common, Underrecognized Mental Disorder].

==Diagnosis==
According to the [[Diagnostic and Statistical Manual of Mental Disorders]], social [[phobia]] is a persistent fear of one or more
situations in which the person is exposed to possible scrutiny by others
and fears that he or she may do something or act in a way that will be
humiliating or embarrassing. <ref
name="dsm-iv">Diagnostic
and Statistical Manual of Mental Disorders IV-TR.
[http://www.behavenet.com/capsules/disorders/socphob.htm Social Phobia].
Retrieved February 21, 2006.</ref> For one to be socially phobic, exposure
to the feared situation must provoke [[anxiety]] and the person must
recognize this anxiety as irrational (although this may be absent in
children). If another disorder is present, the social phobic fear is
unrelated to it. For instance, if a person has a history of panic
attacks,
having a panic attack must not be the sufferer's fear. Sufferers are
typically more self-conscious and self-attentive than others. <ref
name="crozier-primary">Crozier, W. Ray; Alden, Lynn E. ''International
Handbook of Social Anxiety: Concepts, Research, and Interventions
Relating to the Self and Shyness''. page 18. New York John Wiley & Sons,
Ltd. (UK), 2001. ISBN 0-471-49129-2.</ref> As a result, social phobics
tend to limit or remove themselves from situations where they may be
subject to evaluation. Sufferers often recognize their fear is excessive
or irrational, yet can't seem to break out of the cycle. As such, the
diagnosis of social phobia is made only when the fear leads to avoiding
occupational functions, social activities, or relationships with others.<ref name="crozier-cycle">Crozier, page 242.</ref>
Mental health professionals often distinguish between generalized and
[[specific social anxiety disorder]]s. People with generalized social anxiety
have great distress with most or all social situations. A study by
Stanford University established that distress was more likely when
social encounters were unfamiliar, involved power or status differences,
difference in gender, or the presence of a group of people. Those with
specific social phobias may experience anxiety only in a few situations.<ref name="crozier-types">Crozier, page 12.</ref> For example the most
common specific social phobia is [[glossophobia]], the fear of public speaking
or fear of performance,  known as [[stage fright]]. Other examples of specific
social phobias include fears of writing in public (scriptophobia) and
using public restrooms ([[paruresis]]).
There is much debate concerning the relationship between social phobia
and
[[shyness]]. Shyness is not a criterion for social anxiety disorder.
People
with social anxiety disorder may be quite comfortable with certain people
or many people, but still feel intense anxiety in specific social
situations. [[Child psychologist]] Samuel Turner provides a summary
between shyness and social phobia. Both share several features: negative
[[cognition]]s in social situations, heightened
[[physiology|physiological]] reactivity, a tendency to avoid social
situations, and deficits in social skills. Negative cognitions include
fear of negative evaluation, self-consciousness, devaluation of
social
skills, self-deprecating thoughts, and self-blaming attributions for
social
difficulties. Social phobia is distinct from shyness in that it has a
lower
prevalence in the population, follows a more chronic course, is more
functionally debilitating, and has a later age of onset. There are
problems with these kinds of comparisons. It may be that the differences
between them are quantitative rather than qualitative.<ref
name="crozier-shyness">Crozier, page 10.</ref> There are some that argue
that shyness is mistakenly treated with [[medication]] intended for
social
phobia, effectively labeling the [[trait|personality trait]] a mental
illness.<ref name="cnn-shyness">Cable News Network (CNN).

===Criticisms===
Some argue that inherent problems with society such as a competitive
culture, power imbalances, lack of care and poor social education in families cause social anxiety. And consequently the diagnostic boundaries have been
stretched too far and that clinical and media work is promoting the idea
that any problems with shyness or social worries are a pathological
medical condition requiring medical treatment. Some see this as being
driven by [[pharmaceutical companies]], either by direct advertising to
the public or their financial influence on psychiatry.<ref>{{cite journal|

==Symptoms==
===Cognitive Aspects===
In [[cognitive model]]s of Social Anxiety Disorder, social phobics experience
dread over how they will be presented to others. They may be overly
self-conscious, pay high self-attention after the activity, or have high
performance standards for themselves. According to the [[social psychology]]
theory of self-presentation, a sufferer
attempts
to create a well-mannered impression on others but believes he or she is
unable to do so. Many times, prior to the potentially anxiety-provoking
social situation, sufferers may deliberate over what could go wrong and
how to deal with each unexpected case. <!--example-->
After the event, they may have the [[perception]] they performed
unsatisfactorily. Consequently, they will review anything that may have
possibly been abnormal or embarrassing. These thoughts do not just
terminate soon after the encounter, but may extend for weeks or
longer.<ref name="fears">Shyness & Social Anxiety Treatment Australia
[http://www.socialanxietyassist.com.au/common_fears.shtml Social Phobia]</ref> Those with social phobia tend to interpret neutral or
ambiguous conversations with a negative outlook and although still
inconclusive, some studies suggest that socially anxious individuals
remember more negative memories than those less distressed.<ref
name="furmark">Furmark, Thomas.
[http://www.diva-portal.org/diva/getDocument?urn_nbn_se_uu_diva-546-1__fulltext.pdf Social Phobia - From Epidemiology to Brain Function]. Retrieved February
21, 2006.</ref> An example of an instance may be that of an employee
presenting to his co-workers. During the presentation, the person may
[[stutter]] a word upon which he or she may worry that other people
significantly noticed and think that he or she is a terrible presenter.
This cognitive thought propels further anxiety which may lead to further
stuttering, sweating and a possible panic attack.
Recent studies have also shown that a subject with social anxiety might find their average peers to be ignorant, immoral, shallow, and/or mean. A "blank mind" defect can also be observed in many subjects, although research on this topic is still under way.
===Behavioral Aspects===
Social anxiety disorder is a persistent fear of one or more situations in
which the person is exposed to possible scrutiny by others and fears that
he or she may do something or act in a way that will be humiliating or
embarrassing. It exceeds normal "shyness" as it leads to excessive
social avoidance and substantial social or occupational impairment.
Feared activities may include almost any type of social interaction,
especially small groups, dating, parties, talking to strangers,
restaurants, etc. Physical symptoms include "mind going blank", fast
heartbeat, blushing, [[stomach ache]]. Cognitive distortions are a hallmark,
and learned about in CBT (cognitive-behavioral therapy). Thoughts are
often self-defeating and inaccurate.
The groundless fear of the telephone is typical, both calling
somebody and answering the phone. It may appear early in childhood.
According to psychologist [[B.F. Skinner]], [[phobias]] are controlled by
escape and [[avoidance response|avoidance
behaviors]].
For instance, a student may leave the room when talking in front of the
class (escape) and refrain from doing verbal presentations because of the
previously encountered anxiety attack (avoid). Minor avoidance behaviors
are exposed when a person avoids [[eye contact]] and crosses arms to avoid
recognizable [[Tremor|shaking]].<ref name="furmark" /> A [[fight-or-flight response]]
is then triggered in such events. Preventing these automatic responses is
at the core of treatment for social anxiety.
===Physiological Aspects===
Physiological effects, similar to those in other anxiety disorders, are
present in social phobics. Faced with an uncomfortable situation,
children
with social anxiety may display tantrums, weeping, clinging
to parents, and shutting themselves out.<ref name="physiology">eNotes.
[http://health.enotes.com/mental-disorders-encyclopedia/social-phobia#Causes%20and%20symptoms Social phobia - Causes]. Retrieved February 22, 2006.</ref> In adults, it
may be [[tears]] as well as experiencing excessive
[[sweat]]ing, [[nausea]], [[tremor|shaking]], and [[palpitation]]s as a
result of the fight-or-flight response. The walk
disturbance may appear,
especially when passing a group of people. Blushing is commonly
exhibited by individuals suffering from social phobia.<ref name="furmark"/> These visible symptoms further reinforce the anxiety in the presence
of
others. A 2006 study found that the area of the [[brain]] called the
[[amygdala]], part of the [[limbic system]], is [[hyperactive]] when
patients are shown threatening faces or confronted with frightening
situations. They found that patients with more severe social phobia
showed
a [[correlation]] with the increased response in the
amygdala.<ref>[http://www.sciencedaily.com/releases/2006/01/060118205940.htm Studying Brain Activity Could Aid Diagnosis Of Social Phobia]. Monash
University. January 19, 2006.</ref>
==Comorbidity==
There is a high degree of [[comorbidity]] with other psychiatric
disorders. Social phobia often occurs alongside low [[self-esteem]] and
[[clinical depression]], due to lack of personal relationships and long
periods of isolation from avoiding social situations. To try to reduce
their anxiety and alleviate depression, people with social phobia may use
alcohol or other drugs, which can lead to [[substance abuse]]. It is
estimated that one-fifth of patients with social anxiety disorder also
suffer from alcohol dependence.<ref name="sa-alcohol">Alcohol Research

the most common disorders diagnosed in patients with social phobia are
[[panic disorder]] (33 percent), [[generalized anxiety disorder]] (19 percent),
[[post-traumatic stress disorder]] (36 percent), [[substance abuse|substance

anxiety disorder patients who developed comorbid alcoholism, panic
disorder or depression, social anxiety disorder preceded the onset of
alcoholism, panic disorder and depression in 75 percent, 61 percent, and 90 percent of
patients, respectively. [[Avoidant personality disorder]] is also highly
correlated with social phobia.<ref name="crozier-correlation">Crozier,
page 361.</ref> Because of its close relationship and overlapping
symptoms
with other illnesses, treating social phobics may help understand
underlying connection in other psychiatric disorders.
There is research indicating that social anxiety disorder is often correlated with [[bipolar disorder]] [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=16630705&query_hl=5&itool=pubmed_docsum].

[http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=12462857&dopt=Abstract] In addition, studies show that more socially phobic patients treated with anti-depressant medication develop [[hypomania]] than non-phobic controls[http://www.biopsychiatry.com/bipolsp.htm] [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=15820266&dopt=Abstract], although this can be seen as the medication creating a new problem, and also has this adverse effect in a proportion of those without social phobia.

==History==
Literary descriptions of shyness can be traced back to the days of
[[Hippocrates]] around 400 B.C. Hippocrates described someone who 'through bashfulness, suspicion, and timorousness, will not be seen abroad; loves darkness as life and cannot endure the light or to sit in lightsome places; his hat still in his eyes, he will neither see, nor be seen by his good will. He dare not come in company for fear he should be misused, disgraced, overshoot himself in gesture or speeches, or be sick; he thinks every man observes him'.
Charles Darwin wrote about the physiology
and social context of blushing and shyness. The first mention of a
psychiatric term, social phobia ("phobie des situations sociales"), was
made in the early 1900s. Psychologists used the term "[[social neurosis]]"
to describe extremely shy patients in the 1930s. After extensive work by
[[Joseph Wolpe]] on [[systematic desensitization]], research in phobias
and their treatment grew. The idea that social phobia was a separate
entity from other phobias came from the British psychiatrist, [[Isaac Marks]] in the 1960s. This was accepted by the [[American Psychiatric Association]] and was first officially included in the third edition of
the Diagnostic and Statistical Manual of Mental Disorders. The definition
of the phobia was revised in 1989 to allow comorbidity with [[avoidant personality disorder]], and introduced generalized social phobia. <ref name="furmark" /> Social phobia had been largely ignored prior to 1985.
After a call to action by psychiatrist [[Michael Liebowitz]] and
[[clinical psychologist]] [[Richard Heimberg]], there was an increase in
research and attention on the disorder. The DSM-IV gave social phobia the
alternative name Social Anxiety Disorder. Research in to the psychology
and sociology of everyday social anxiety continued. Cognitive Behavioural
models and therapies were developed for social anxiety disorder. In the
1990s<!-- when exactly? -->, [[paroxetine]] became the first prescription
drug in the US approved to treat social anxiety disorder, with others
following.

Overview

Social phobia is a diagnosis within psychiatry and other mental health professions referring to excessive anxiety in social situations causing relatively extreme distress and impaired ability to function in at least some areas of daily life. The diagnosis can be of a specific disorder (when only some particular situations are feared) or a generalized disorder. Generalized social anxiety disorder typically involves a persistent, intense, and chronic fear of being judged by others and of potentially being embarrassed or humiliated by their own actions. These fears can be triggered by perceived or actual scrutiny by others. While the fear of social interaction may be recognized by the person as excessive or unreasonable, considerable difficulty can be encountered overcoming it. Approximately 13.3 percent of the general population may meet criteria for social anxiety disorder at some point in their lifetime, according to the highest survey estimate, with the male to female ratio being 1:1.5.[1]

Physical symptoms often accompanying social anxiety disorder include excessive blushing, sweating (hyperhidrosis), trembling, palpitations, nausea, and stammering. Panic attacks may also occur under intense fear and discomfort. An early diagnosis may help in minimizing the symptoms and the development of additional problems such as depression. Some sufferers may use alcohol or other drugs to reduce fears and inhibitions at social events.

A person with the disorder may be treated with psychotherapy, medication, or both. Research has shown cognitive behavior therapy, whether individually or in a group, to be effective in treating social phobia. The cognitive and behavioral components seek to change thought patterns and physical reactions to anxious situations. Prescribed medications includes two classes of antidepressants: selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). Attention given to social anxiety disorder has significantly increased in the US since 1999 with the approval and marketing of drugs for its treatment.

Historical Perspective

Literary descriptions of shyness can be traced back to the days of Hippocrates around 400 B.C. Hippocrates described someone who 'through bashfulness, suspicion, and timorousness, will not be seen abroad; loves darkness as life and cannot endure the light or to sit in lightsome places; his hat still in his eyes, he will neither see, nor be seen by his good will. He dare not come in company for fear he should be misused, disgraced, overshoot himself in gesture or speeches, or be sick; he thinks every man observes him'.

Charles Darwin wrote about the physiology and social context of blushing and shyness. The first mention of a psychiatric term, social phobia ("phobie des situations sociales"), was made in the early 1900s. Psychologists used the term "social neurosis" to describe extremely shy patients in the 1930s. After extensive work by Joseph Wolpe on systematic desensitization, research in phobias and their treatment grew. The idea that social phobia was a separate entity from other phobias came from the British psychiatrist, Isaac Marks in the 1960s. This was accepted by the American Psychiatric Association and was first officially included in the third edition of the Diagnostic and Statistical Manual of Mental Disorders. The definition of the phobia was revised in 1989 to allow comorbidity with avoidant personality disorder, and introduced generalized social phobia. [2] Social phobia had been largely ignored prior to 1985. After a call to action by psychiatrist Michael Liebowitz and clinical psychologist Richard Heimberg, there was an increase in research and attention on the disorder. The DSM-IV gave social phobia the alternative name Social Anxiety Disorder. Research in to the psychology and sociology of everyday social anxiety continued. Cognitive Behavioural models and therapies were developed for social anxiety disorder. In the 1990s, paroxetine became the first prescription drug in the US approved to treat social anxiety disorder, with others following.

Causes

Research into the causes of social anxiety and social phobia is wide-ranging, encompassing multiple perspectives from neuroscience to sociology. Scientists have yet to pinpoint the exact causes. Studies suggest that genetics can play a part in combination with environmental factors.

Genetic and Family Factors

It has been shown that there is a two to threefold greater risk of having social phobia if a first-degree relative also has the disorder. This could be due to genetics and/or due to children acquiring social fears and avoidance through processes of observational learning or parental psychosocial education. Studies of identical twins brought up (via adoption) in different families have indicated that, if one twin developed social anxiety disorder, then the other was between 30 percent and 50 percent more likely than average to also develop the disorder.[3] To some extent this 'heritability' may not be specific - for example, studies have found that if a parent has any kind of anxiety disorder or clinical depression, then a child is somewhat more likely to develop an anxiety disorder or social phobia.[4] Studies suggest that parents of those with social anxiety disorder tend to be more socially isolated themselves (Bruch and Heimberg, 1994; Caster et al, 1999), and shyness in adoptive parents is significantly correlated with shyness in adopted children (Daniels and Plomin, 1985);

Adolescents who were rated as having an insecure (anxious-ambivalent) attachment with their mother as infants were twice as likely to develop anxiety disorders by late adolescence,[5] including social phobia.

A related line of research has investigated 'behavioural inhibition' in infants – early signs of an inhibited and introspective or fearful nature. Studies have shown that around 10-15 percent of individuals show this early temperament, which appears to be partly due to genetics. Some continue to show this trait in to adolescence and adulthood, and appear to be more likely to develop social anxiety disorder.[6]

Social Experiences

A previous negative social experience can be a trigger to social phobia.[7] [8] perhaps particularly for individuals high in 'interpersonal sensitivity'. For around half of those diagnosed with social anxiety disorder, a specific traumatic or humiliating social event appears to be associated with the onset or worsening of the disorder;[9] this kind of event appears to be particularly related to specific (performance) social phobia, for example regarding public speaking (Stemberg et al., 1995). As well as direct experiences, observing or hearing about the socially negative experiences of others (e.g. a faux pas committed by someone), or verbal warnings of social problems and dangers, may also make the development of a social anxiety disorder more likely.[10] Social anxiety disorder may be caused by the longer-term effects of not fitting in, or being bullied, rejected or ignored (Beidel and Turner, 1998). Shy adolescents or avoidant adults have emphasised unpleasant experiences with peers[11] or childhood bullying or harassment (Gilmartin, 1987). In one study, popularity was found to be negatively correlated with social anxiety, and children who were neglected by their peers reported higher social anxiety and fear of negative evaluation than other categories of children.[12] Socially phobic children appear less likely to receive positive reactions from peers[13] and anxious or inhibited children may isolate themselves.[14]

Social/Cultural Influences

Cultural factors that have been related to social anxiety disorder include a society's attitude towards shyness and avoidance, affecting ability to form relationships or access employment or education. One study found that the effects of parenting are different depending on the culture - American children appear more likely to develop social anxiety disorder if their parents emphasise the importance of other's opinions and use shame as a disciplinary strategy (Leung et al., 1994), but this association was not found for Chinese/Chinese-American children. In China, research has indicated that shy-inhibited children are more accepted than their peers and more likely to be considered for leadership and considered competent, in contrast to the findings in Western countries.[15] Purely demographic variables may also play a role - for example there are possibly lower rates of social anxiety disorder in Mediterranean countries and higher rates in Scandinavian countries, and it has been hypothesised that hot weather and high-density may reduce avoidance and increase interpersonal contact.

Problems in developing social skills, or 'social effectiveness', may be a cause of some social anxiety disorder, through either inability or lack of confidence to interact socially and gain positive reactions and acceptance from others. The studies have been mixed, however, with some studies not finding significant problems in social skills[16] while others have.[17] What does seem clear is that the socially anxious perceive their own social skills to be low. It may be that the increasing need for sophisticated social skills in forming relationships or careers, and an emphasis on assertiveness and competitiveness, is making social anxiety problems more common, at least among the 'middle classes'.[18] An interpersonal or media emphasis on 'normal' or 'attractive' personal characteristics has also been argued to fuel perfectionism and feelings of inferiority or insecurity regarding negative evaluation from others. The need for social acceptance or social standing has been elaborated in other lines of research relating to social anxiety[19]

Evolutionary Context

A long-accepted evolutionary explanation of anxiety is that it reflects an in-built 'fight or flight' system, which errs on the side of safety. One line of research suggests that specific dispositions to monitor and react to social threats may have evolved, reflecting the vital and complex importance of social living and social rank in human ancestral environments. Charles Darwin originally wrote about the evolutionary basis of shyness and blushing, and modern evolutionary psychology and psychiatry also addresses social phobia in this context.[20] It has been hypothesised that in modern day society these evolved tendencies can become more inappropriately activated and result in some of the cognitive 'distortions' or 'irrationalities' identified in cognitive-behavioural models and therapies[21]

Neurochemical and Neurocognitive Influences

Some scientists hypothesize that social phobia is related to an imbalance of the brain chemical serotonin. Sociability is also closely tied to dopamine neurotransmission. Low D2 receptor binding is found in people with social anxiety.[22] The efficacy of medications which affect serotonin and dopamine levels also indicates the role of these pathways. There is also increasing focus on other candidate transmitters, e.g. Norepinephrine, which may be over-active in social anxiety disorder, and the inhibitory transmitter GABA.

Individuals with social anxiety disorder have been found to have a hypersensitive amygdala, for example in relation to social threat cues (e.g. someone might be evaluating you negatively), angry or hostile faces, and while just waiting to give a speech.[23] Recent research has also indicated that another area of the brain, the 'Anterior cingulate cortex', which was already known to be involved in the experience of physical pain, also appears to be involved in the experience of 'social pain', for example perceiving group exclusion.[24]

Psychological Factors

Research has indicated the role of 'core' or 'unconditional' negative beliefs (e.g. I am inept) and 'conditional' beliefs nearer to the surface (e.g. If I show myself, I will be rejected). They are thought to develop based on personality and adverse experiences and to be activated when the person feels under threat.[25] One line of work has focused more specifically on the key role of self-presentational concerns.[26][27] The resulting anxiety states are seen as interfering with social performance and the ability to concentrate on interaction, which in turn creates more social problems, which strengthens the negative schema. Also highlighted has been a high focus on and worry about anxiety symptoms themselves and how they might appear to others.[28] A similar model[29] emphasises the development of a distorted mental representation of their self and over-estimates of the likelihood and consequences of negative evaluation, and of the performance standards that others have. Such cognitive-behavioral models consider the role of negatively-biased memories of the past and the processes of rumination after an event, and fearful anticipation before it. Studies have also highlighted the role of subtle avoidance and defensive factors, and shown how attempts to avoid feared negative evaluations or use 'safety behaviours' (Clark & Wells, 1995) can make social interaction more difficult and the anxiety worse in the long run. This work has been influential in the development of Cognitive Behavioural Therapy for social anxiety disorder, which has been shown to have efficacy.

Differential Diagnosis

  • Other mental disorders

Social phobia should not be confused with panic disorder. Sufferers of panic disorder are sometimes convinced that their panic comes from some dire physical cause, and often go to the hospital or call for an ambulance during or after their attacks. Social phobics may experience a panic attack when triggered, but they are aware that it is extreme anxiety they are experiencing, and that the cause is an irrational fear. Few social phobics would willingly go to a hospital in that instance because they fear rejection and judgment by authority figures (such as the medical staff). The general form of social anxiety is sometimes incorrectly called generalized anxiety disorder. The principal difference between the two is that the social phobia deals with anxiety in a social setting, while generalized anxiety disorder is extreme anxiety for any situation (work, school, et al.), not necessarily one involving other people.

When prevalence estimates were based on the examination of psychiatric clinic samples, social anxiety disorder was thought to be a relatively rare disorder. The opposite was instead true; social anxiety was common but many were afraid to seek psychiatric help, leading to an understatement of the problem.[2] Prevalence rates vary widely because of its vague diagnostic criteria and its overlapping symptoms with other disorders. There has been some debate on how the studies are conducted and whether the illness truly impairs the respondents as laid out in the official criteria. Psychologist Dr. Ray Crozier argues, "it is difficult to ascertain whether the person being interviewed adheres to the DSM-III-R criteria or whether they are merely exhibiting poor social skills or shyness."[31]

The National Comorbidity Survey of over 8,000 American correspondents in 1994 revealed a 12-month and lifetime prevalence rates of 7.9 percent and 13.3 percent making it the third most prevalent psychiatric disorder after depression and alcohol dependence and the most apparent of the anxiety disorders.[32] According to U.S. epidemiological data from the National Institute of Mental Health, social phobia affects 5.3 million adult Americans in any given year. Cross-cultural studies have reached prevalence rates with the conservative rates at 5 percent of the population.[33][34] However, other estimates vary within 2 percent and 7 percent of the U.S. adult population.[35]

Onset of social phobia typically occurs between 11 and 19 years of age. Onset after age 25 is rare. Social anxiety disorder occurs in females nearly twice as often as males, although men are more likely to seek help.[36] The prevalence of social phobia appears to be increasing among white, married, and well-educated individuals. As a group, those with generalized social phobia are less likely to graduate from high school and are more likely to rely on government financial assistance or have poverty-level salaries.[37] Surveys carried out in 2002 show the youth of England, Scotland, and Wales have a prevalence rate of 0.4 percent, 1.8 percent, and 0.6 percent, respectively.[38] The prevalence of self-reported social anxiety for Nova Scotians older than 14 years was 4.2 percent in June 2004 with women (4.6 percent) reporting more than men (3.8 percent).[39] In Australia, social phobia is the 8th and 5th leading disease or illness for males and females between 15-24 years of age as of 2003.[40] Because of the difficulty in separating social phobia from poor social skills or shyness, some studies have a large range of prevalence.[41] The table also shows higher prevalence in Brazil.

Diagnosis

According to the Diagnostic and Statistical Manual of Mental Disorders, social phobia is a persistent fear of one or more situations in which the person is exposed to possible scrutiny by others and fears that he or she may do something or act in a way that will be humiliating or embarrassing. [42] For one to be socially phobic, exposure to the feared situation must provoke anxiety and the person must recognize this anxiety as irrational (although this may be absent in children). If another disorder is present, the social phobic fear is unrelated to it. For instance, if a person has a history of panic attacks, having a panic attack must not be the sufferer's fear. Sufferers are typically more self-conscious and self-attentive than others. [43] As a result, social phobics tend to limit or remove themselves from situations where they may be subject to evaluation. Sufferers often recognize their fear is excessive or irrational, yet can't seem to break out of the cycle. As such, the diagnosis of social phobia is made only when the fear leads to avoiding occupational functions, social activities, or relationships with others.[44]

Mental health professionals often distinguish between generalized and specific social anxiety disorders. People with generalized social anxiety have great distress with most or all social situations. A study by Stanford University established that distress was more likely when social encounters were unfamiliar, involved power or status differences, difference in gender, or the presence of a group of people. Those with specific social phobias may experience anxiety only in a few situations.[45] For example the most common specific social phobia is glossophobia, the fear of public speaking or fear of performance, known as stage fright. Other examples of specific social phobias include fears of writing in public (scriptophobia) and using public restrooms (paruresis).

There is much debate concerning the relationship between social phobia and shyness. Shyness is not a criterion for social anxiety disorder. People with social anxiety disorder may be quite comfortable with certain people or many people, but still feel intense anxiety in specific social situations. Child psychologist Samuel Turner provides a summary between shyness and social phobia. Both share several features: negative cognitions in social situations, heightened physiological reactivity, a tendency to avoid social situations, and deficits in social skills. Negative cognitions include fear of negative evaluation, self-consciousness, devaluation of social skills, self-deprecating thoughts, and self-blaming attributions for social difficulties. Social phobia is distinct from shyness in that it has a lower prevalence in the population, follows a more chronic course, is more functionally debilitating, and has a later age of onset. There are problems with these kinds of comparisons. It may be that the differences between them are quantitative rather than qualitative.[46] There are some that argue that shyness is mistakenly treated with medication intended for social phobia, effectively labeling the personality trait a mental illness.[47]

DSM-V Diagnostic Criteria for Social Phobia[30]

  • A. Marked fear or anxiety about one or more social situations in which the individual is exposed to possible scrutiny by others. Examples include social interactions (e.g., having a conversation, meeting unfamiliar people), being observed (e.g., eating or drinking),and performing in front of others (e.g., giving a speech).

Note:In children, the anxiety must occur in peer settings and not just during interactions with adults.

AND

  • B. The individual fears that he or she will act in a way or show anxiety symptoms that will be negatively evaluated (i.e., will be humiliating or embarrassing: will lead to rejection or offend others).

AND

  • C. The social situations almost always provoke fear or anxiety.

Note:In children, the fear or anxiety may be expressed by crying, tantrums, freezing,clinging, shrinking, or failing to speak in social situations.

AND

  • D. The social situations are avoided or endured with intense fear or anxiety.

AND

  • E. The fear or anxiety is out of proportion to the actual threat posed by the social situation and to the socio cultural context.

AND

  • F. The fear, anxiety, or avoidance is persistent, typically lasting for 6 months or more.

AND

  • G. The fear, anxiety, or avoidance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.

AND

  • H. The fear, anxiety, or avoidance is not attributable to the physiological effects of a substance(e.g., a drug of abuse, a medication) or another medical condition.

AND

AND

  • J. If another medical condition (e.g., Parkinson’s disease, obesity, disfigurement from bums or injury) is present, the fear, anxiety, or avoidance is clearly unrelated or is excessive.

Specify if:

  • Performance only: If the fear is restricted to speaking or performing in public.

Criticisms

Some argue that inherent problems with society such as a competitive culture, power imbalances, lack of care and poor social education in families cause social anxiety. And consequently the diagnostic boundaries have been stretched too far and that clinical and media work is promoting the idea that any problems with shyness or social worries are a pathological medical condition requiring medical treatment. Some see this as being driven by pharmaceutical companies, either by direct advertising to the public or their financial influence on psychiatry.[48] This view can be associated with, but is not exclusive to, anti-psychiatry.

Symptoms

Cognitive Aspects

In cognitive models of Social Anxiety Disorder, social phobics experience dread over how they will be presented to others. They may be overly self-conscious, pay high self-attention after the activity, or have high performance standards for themselves. According to the social psychology theory of self-presentation, a sufferer attempts to create a well-mannered impression on others but believes he or she is unable to do so. Many times, prior to the potentially anxiety-provoking social situation, sufferers may deliberate over what could go wrong and how to deal with each unexpected case. After the event, they may have the perception they performed unsatisfactorily. Consequently, they will review anything that may have possibly been abnormal or embarrassing. These thoughts do not just terminate soon after the encounter, but may extend for weeks or longer.[49] Those with social phobia tend to interpret neutral or ambiguous conversations with a negative outlook and although still inconclusive, some studies suggest that socially anxious individuals remember more negative memories than those less distressed.[2] An example of an instance may be that of an employee presenting to his co-workers. During the presentation, the person may stutter a word upon which he or she may worry that other people significantly noticed and think that he or she is a terrible presenter. This cognitive thought propels further anxiety which may lead to further stuttering, sweating and a possible panic attack. Recent studies have also shown that a subject with social anxiety might find their average peers to be ignorant, immoral, shallow, and/or mean. A "blank mind" defect can also be observed in many subjects, although research on this topic is still under way.

Behavioral Aspects

Social anxiety disorder is a persistent fear of one or more situations in which the person is exposed to possible scrutiny by others and fears that he or she may do something or act in a way that will be humiliating or embarrassing. It exceeds normal "shyness" as it leads to excessive social avoidance and substantial social or occupational impairment. Feared activities may include almost any type of social interaction, especially small groups, dating, parties, talking to strangers, restaurants, etc. Physical symptoms include "mind going blank", fast heartbeat, blushing, stomach ache. Cognitive distortions are a hallmark, and learned about in CBT (cognitive-behavioral therapy). Thoughts are often self-defeating and inaccurate.

The groundless fear of the telephone is typical, both calling somebody and answering the phone. It may appear early in childhood.

According to psychologist B.F. Skinner, phobias are controlled by escape and avoidance behaviors. For instance, a student may leave the room when talking in front of the class (escape) and refrain from doing verbal presentations because of the previously encountered anxiety attack (avoid). Minor avoidance behaviors are exposed when a person avoids eye contact and crosses arms to avoid recognizable shaking.[2] A fight-or-flight response is then triggered in such events. Preventing these automatic responses is at the core of treatment for social anxiety.

Physiological Aspects

Physiological effects, similar to those in other anxiety disorders, are present in social phobics. Faced with an uncomfortable situation, children with social anxiety may display tantrums, weeping, clinging to parents, and shutting themselves out.[50] In adults, it may be tears as well as experiencing excessive sweating, nausea, shaking, and palpitations as a result of the fight-or-flight response. The walk disturbance may appear, especially when passing a group of people. Blushing is commonly exhibited by individuals suffering from social phobia.[2] These visible symptoms further reinforce the anxiety in the presence of others. A 2006 study found that the area of the brain called the amygdala, part of the limbic system, is hyperactive when patients are shown threatening faces or confronted with frightening situations. They found that patients with more severe social phobia showed a correlation with the increased response in the amygdala.[51]

Comorbidity

There is a high degree of comorbidity with other psychiatric disorders. Social phobia often occurs alongside low self-esteem and clinical depression, due to lack of personal relationships and long periods of isolation from avoiding social situations. To try to reduce their anxiety and alleviate depression, people with social phobia may use alcohol or other drugs, which can lead to substance abuse. It is estimated that one-fifth of patients with social anxiety disorder also suffer from alcohol dependence.[52] The most common complementary psychiatric condition is unipolar depression. In a sample of 14,263 people, of the 2.4 percent of persons diagnosed with social phobia, 16.6 percent also met the criteria for clinical depression.[53] Besides depression, the most common disorders diagnosed in patients with social phobia are panic disorder (33 percent), generalized anxiety disorder (19 percent), post-traumatic stress disorder (36 percent), substance abuse disorder (18 percent), and attempted suicide (23 percent).[54] In one study of social anxiety disorder patients who developed comorbid alcoholism, panic disorder or depression, social anxiety disorder preceded the onset of alcoholism, panic disorder and depression in 75 percent, 61 percent, and 90 percent of patients, respectively. Avoidant personality disorder is also highly correlated with social phobia.[55] Because of its close relationship and overlapping symptoms with other illnesses, treating social phobics may help understand underlying connection in other psychiatric disorders.

There is research indicating that social anxiety disorder is often correlated with bipolar disorder [9]. Some researchers believe they share an underlying cyclothymic-anxious-sensitive disposition. [10] In addition, studies show that more socially phobic patients treated with anti-depressant medication develop hypomania than non-phobic controls[11] [12], although this can be seen as the medication creating a new problem, and also has this adverse effect in a proportion of those without social phobia.

Treatment

Arguably the most important clinical point to emerge from studies of social anxiety disorder is the benefit of early diagnosis and treatment. Social anxiety disorder remains under-recognized in primary care practice, with patients often presenting for treatment only after the onset of complications such as clinical depression or substance abuse disorders. The patients who achieve full resolution are usually far fewer; there are still many who, after receiving treatment, are unable to function in the long-term without anxiety symptoms.

Research has provided evidence for the efficacy of two forms of treatment available for social phobia: certain medications and a specific form of short-term psychotherapy called Cognitive-behavioral therapy (CBT), the central component being gradual exposure therapy.

Pharmacological Treatments

SSRIs

Selective serotonin reuptake inhibitors (SSRIs), a class of antidepressants, are considered by many to be the first choice medication for generalised social phobia. These drugs elevate the level of the neurotransmitter serotonin, among other effects. The first drug formally approved by the Food and Drug Administration was paroxetine, sold as Paxil in the US or Seroxat in the UK, Compared to older forms of medication, there is less risk of tolerability and drug dependency.[56] However, their efficacy and increased suicide risk has been subject to controversy.

In a 1995 double-blind, placebo-controlled trial, the SSRI paroxetine was shown to result in clinically meaningful improvement in 55 percent of patients with generalized social anxiety disorder, compared with 23.9 percent of those taking placebo.[57] An October 2004 study yielded similar results. Patients were treated with either fluoxetine, psychotherapy, fluoxetine and psychotherapy, placebo and psychotherapy, and a placebo. The first four sets saw improvement in 50.8 to 54.2 percent of the patients. Of those assigned to receive only a placebo, 31.7 percent achieved a rating of 1 or 2 on the Clinical Global Impression-Improvement scale. Those who sought both therapy and medication did not see a boost in improvement.[58]

General side-effects are common during the first weeks while the body adjusts to the drug. Symptoms may include headaches, nausea, insomnia and changes in sexual behavior. Treatment safety during pregnancy has not been established.[59] In late 2004 much media attention was given to a proposed link between SSRI use and juvenile suicide. For this reason, the use of SSRIs in pediatric cases of depression is now recognized by the Food and Drug Administration as warranting a cautionary statement to the parents of children who may be prescribed SSRIs by a family doctor.[60] Recent studies have shown no increase in rates of suicide.[61] These tests, however, represent those diagnosed with depression, not necessarily with social anxiety disorder. However, it should be noted that due to the nature of the conditions, those taking SSRIs for social phobias are far less likely to have suicidal ideation than those with depression.

Other Drugs

Although SSRIs are often the first choice for treatment, other prescription drugs are also commonly issued, sometimes only if SSRIs fail to produce any clinically significant improvement.

In 1985, before the introduction of SSRIs, anti-depressants such as monoamine oxidase inhibitors (MAOIs) were frequently used in the treatment of social anxiety. Their efficacy appears to be comparable or sometimes superior to SSRIs or Benzodiazepines. However, because of the dietary restrictions required, high toxicity in overdose, and incompatibilities with other drugs, its usefulness as a treatment for social phobics is now limited. Some argue for their continued use, however, or that a special diet does not need to be strictly adhered to.[62] A newer type of this medication, Reversible inhibitors of monoamine oxidase subtype A (RIMAs) inhibit the MAO enzyme only temporarily, improving the adverse-effect profile but possibly reducing their efficacy.

Benzodiazepines are a short-acting and more potent alternative to SSRIs. The drug is often used for short-term relief of severe, disabling anxiety. Although benzodiazepines are still sometimes prescribed for long-term use in some countries, there is much concern over the development of drug tolerance, dependency and recreational abuse. Benzodiazepines augment the action of GABA, the major inhibitory neurotransmitter in the brain; effects usually begin to appear within minutes or hours.

Some people with a form of social phobia called performance phobia have been helped by beta-blockers, which are more commonly used to control high blood pressure. Taken in low doses, they control the physical manifestation of anxiety and can be taken before a public performance.

A novel treatment approach has recently been developed as a result of translational research. It has been shown that a combination of acute dosing of d-cycloserine (DCS) with exposure therapy facilitates the effects of exposure therapy of social phobia (Hofmann, Meuret, Smits, et al., 2006). DCS is an old antibiotic medication used for treating tuberculosis and does not have any anxiolytic properties per se. However, it acts as an agonist at the glutamatergic N-methyl-D-aspartate (NMDA) receptor site, which is important for learning and memory (Hofmann, Pollack, & Otto, 2006). It has been shown that administering a small dose acutely 1 hour before exposure therapy can facilitate extinction learning that occurs during therapy.

Psychotherapy

Research has shown that a form of psychotherapy that is effective for several anxiety disorders, particularly panic disorder and social phobia[63] is cognitive-behavioral therapy (CBT). It has two main components. The cognitive component helps people become aware of and to change thinking patterns that keep them from overcoming their fears. A person with social phobia might be helped to question how they can be so sure that others are continually watching and harshly judging him or her. The behavioral component of CBT seeks to change people's reactions to anxiety-provoking situations. It also serves as a logical extension of cognitive therapy where people are shown proof in the real world that their dysfunctional thought processes are unrealistic. A key element of this component is gradual exposure, in which people confront the things they fear in a structured, sensitive manner. Gradual exposure is an inherently unpleasant technique. It involves four components, duration, frequency, graded and focused. Ideally the person should be exposed to a feared social situation that is anxiety provoking but bearable (graded) for as long as possible (duration), two to three times a day (frequency), and the person must endure the anxiety until it declines (focused). A hierarchy of feared steps is constructed and the patient is exposed to each step. The aim is also to learn from acting differently and observing reactions (behavioral 'experiments'). This is intended to be done with support and guidance when the therapist and patient feel they are ready. Cognitive-behavior therapy for social phobia also includes anxiety management training, which may include techniques such as deep breathing and muscle relaxation exercises, which may be practiced 'in-situ'. CBT may also be conducted partly in group sessions (Cognitive behavioral group therapy), facilitating the sharing of experiences, a sense of acceptance by others and undertaking behavioral challenges in a trusted environment (Heimberg).

Some studies have suggested social skills training can help with social anxiety[64]. Whether specific social skills techniques and training are required, rather than just support with general social functioning and exposure to social situations, does not seem to be clear[65].

Interpersonal Therapy has been shown to have efficacy for depression and a small study of the therapy in the treatment of social phobia suggests it may also work with social phobia[66].
