Social Anxiety Disorder (Social Phobia)

Social anxiety disorder, also called social phobia, is an anxiety disorder in which a person has intense, persistent fear of social or performance situations where they might be watched, judged or embarrassed. The fear is out of proportion to the actual situation, lasts six months or more, and leads to avoidance or enduring situations with great distress. U.S. surveys estimate that about 12% of adults experience it at some point in life, making it one of the most common mental health conditions.

Social anxiety disorder is far more than shyness. It can affect friendships, dating, education and careers, and many people live with it for years before seeking help. It is also highly treatable.

Understanding Social Anxiety

Beyond shyness and introversion

Social anxiety exists on a continuum. Shyness is a common personality trait involving some discomfort or reticence, particularly with new people, that usually does not stop people doing what they want. Introversion is a preference for quieter settings and time alone; it is not driven by fear, and introverts can be socially confident. Social anxiety disorder involves intense fear of negative evaluation, significant avoidance and real impairment. Many people with social anxiety disorder would like more social connection but feel blocked by fear.

History

French psychiatrist Pierre Janet described "phobie des situations sociales" in the early twentieth century. Social phobia entered the DSM-III in 1980 and was long called "the neglected anxiety disorder", a phrase associated with psychiatrist Michael Liebowitz, who developed the widely used Liebowitz Social Anxiety Scale. The DSM-IV added "social anxiety disorder" as an alternative name, and the DSM-5 (2013) made it the main term, replaced the "generalized" subtype with a "performance only" specifier, and removed the requirement that adults recognise their fear as excessive.

Core features

At the heart of social anxiety is fear of negative evaluation: the expectation that others will notice flaws, mistakes or signs of anxiety and judge the person as boring, incompetent, weird or unlikeable. Closely linked is self-focused attention: during social situations, attention turns inward to monitor heartbeat, sweating, voice and how one appears, which makes it harder to follow conversations and pick up others' friendly signals. Many people also experience anticipatory anxiety, dreading events days or weeks in advance and rehearsing conversations repeatedly.

Patterns of social anxiety

For some people, fear is mainly limited to performance situations such as public speaking or performing music; the DSM-5-TR uses the specifier "performance only" for this pattern. For others, fear spans many social situations, including everyday conversation, eating in front of others and meeting new people, which tends to be more impairing. See performance anxiety and public speaking for related topics.

Symptoms and Manifestations

The descriptions below explain what clinicians look for. They are for understanding, not self-diagnosis; a qualified professional can provide an assessment.

Physical symptoms

Social situations can trigger the body's fight-or-flight response. People often especially fear visible symptoms, such as blushing, sweating, trembling hands or a shaky voice, because they worry others will notice and judge them. Internal symptoms include a racing heart, breathlessness, dizziness, nausea, muscle tension, dry mouth and the mind "going blank".

Cognitive symptoms

Before social events, people commonly make catastrophic predictions and recall past embarrassments. During them, typical patterns include "mind reading" (assuming others think badly of them), overestimating how noticeable they are, a bias toward negative cues, and personalising neutral events. Afterward, many people engage in post-event processing, a detailed and critical replay of the interaction that focuses on perceived mistakes and discounts positive moments. This form of rumination can strengthen negative beliefs.

Behavioral symptoms

Obvious avoidance includes declining invitations, avoiding phone calls, skipping class presentations or turning down jobs that involve meeting people. More subtle safety behaviors include avoiding eye contact, speaking quietly, over-preparing what to say, staying near a "safe" person, wearing clothing to hide blushing, gripping a glass to hide trembling, or using alcohol to cope. These behaviors feel protective but often maintain anxiety.

Emotional impact

People with social anxiety commonly describe shame and embarrassment, loneliness, frustration at missed opportunities, and low self-esteem. Over time, many develop low mood or depression.

Feared Social Situations

People differ in which situations they fear most. Common groups include:

Dating and relationships can be particularly affected; see dating anxiety. Job interviews are another common source of difficulty, discussed in job interview psychology.

Causes and Risk Factors

Genetic and temperamental factors

Social anxiety runs in families. Twin studies suggest a moderate genetic contribution, with much of the inherited risk shared with other anxiety disorders. Children with a behaviorally inhibited temperament, who are cautious, quiet and wary in unfamiliar situations, are at higher risk of later social anxiety, as shown in long-term studies associated with psychologist Jerome Kagan and colleagues. Brain imaging studies find heightened amygdala responses to social threat cues, such as critical faces, in many people with social anxiety.

Learning and life experiences

Humiliating or frightening social experiences, such as being bullied, teased or publicly embarrassed, can contribute, as can growing up with limited opportunities to develop social confidence. Children may also learn social fears by observing anxious or socially avoidant parents (observational learning) or through parenting that is overprotective or highly critical. Many people with social anxiety cannot recall a specific triggering event.

Cognitive models

The most influential explanations of why social anxiety persists are cognitive models. In Clark and Wells's model (1995), people with social anxiety enter situations with negative assumptions about how they come across. When anxious, they shift attention inward and build a distorted mental image of how they appear to others, often from an "observer perspective", as if seeing themselves through others' eyes. They use safety behaviors that prevent disconfirmation of their fears, and they engage in anticipatory worry and post-event rumination. Rapee and Heimberg's model (1997) similarly emphasises a mental representation of how one appears to others and vigilance for signs of negative evaluation. These models underpin modern cognitive therapy.

Social and cultural factors

Culture shapes what is feared. Social norms about eye contact, assertiveness and modesty vary. In Japan and Korea, clinicians describe taijin kyofusho, a fear of offending or making others uncomfortable through one's appearance, gaze or body odour, which overlaps with but differs from Western descriptions of social anxiety. Research also explores how social media and reduced face-to-face contact may interact with social anxiety, with mixed findings.

Diagnosis and Assessment

DSM-5-TR criteria

The DSM-5-TR describes social anxiety disorder as follows. In summary, clinicians look for marked fear or anxiety about one or more social situations involving possible scrutiny by others (in children, this must occur with peers, not just adults); fear of acting in a way, or showing anxiety symptoms, that will be negatively evaluated; social situations almost always provoking fear; avoidance or endurance with intense fear; fear out of proportion to the actual threat and cultural context; duration of six months or more; significant distress or impairment; and that the fear is not better explained by substances, a medical condition or another mental disorder. If a medical condition such as a visible tremor or disfigurement is present, the fear must be clearly unrelated or excessive.

Assessment tools

Clinicians use interviews and questionnaires such as the Liebowitz Social Anxiety Scale, the Social Phobia Inventory (SPIN) and the Social Interaction Anxiety Scale. These measure severity and track progress; they support but do not replace a clinician's judgement.

Differential diagnosis and co-occurring conditions

Clinicians distinguish social anxiety disorder from avoidant personality disorder, which involves more pervasive feelings of inadequacy and overlaps heavily with severe social anxiety; panic disorder, where fear centres on panic attacks; agoraphobia; autism, where social difficulties stem from differences in social communication (see autism vs. social anxiety); body dysmorphic disorder; and depression. Social anxiety disorder often co-occurs with depression, other anxiety disorders and substance use problems, and in children it is closely linked with selective mutism.

Treatment Approaches

Cognitive behavioral therapy

Cognitive behavioral therapy (CBT) is the most extensively researched treatment for social anxiety disorder. A large network meta-analysis by Evan Mayo-Wilson and colleagues (2014), conducted for the UK's National Institute for Health and Care Excellence (NICE), found that individual CBT had among the largest effects of all psychological and medication treatments, and NICE recommends it as the first-line treatment for adults.

The version with particularly strong evidence is cognitive therapy for social anxiety, developed by David M. Clark and colleagues from the Clark and Wells model. It includes:

• Building a personal model of how the person's thoughts, self-focus and safety behaviors keep their anxiety going.
• Experiments with safety behaviors and attention, such as having a conversation once with safety behaviors and once without, then comparing how anxious they felt and how they came across.
• Video and audio feedback to correct distorted self-images: people often discover they look much less anxious than they felt.
• Attention training to shift focus outward onto the conversation and other people.
• Behavioral experiments in real situations to test feared predictions.
• Dealing with anticipatory worry and post-event rumination, and updating negative memories and beliefs.

Group CBT

Group CBT, developed by Richard Heimberg and others, offers built-in opportunities for exposure and feedback from peers and can be cost-effective. Evidence supports it, although individual cognitive therapy appears somewhat more effective in comparative studies.

Internet-delivered CBT

Guided internet-delivered CBT programmes, with regular support from a therapist, have good research support and can help people who find it hard to attend in person. Virtual reality exposure is also being studied.

Mindfulness and acceptance-based approaches

Mindfulness-based programmes and acceptance and commitment therapy (ACT), which emphasises acting on personal values despite anxiety, show promising results, though their evidence base is smaller than that for CBT. Psychodynamic therapy has some evidence and may be considered when CBT is declined.

Exposure Therapy

Principles

Exposure means deliberately and repeatedly entering feared social situations in a planned way. Older explanations emphasised habituation, the natural drop in anxiety with time. Current explanations emphasise new learning: by staying in situations without safety behaviors, people discover that feared outcomes are less likely or less catastrophic than predicted, and that they can cope with anxiety. This approach is often combined with cognitive techniques.

Building a hierarchy

Many therapists help people build an exposure hierarchy, ranking situations by expected anxiety. An example might start with saying hello to a cashier, then making small talk with a colleague, asking a question in a meeting, disagreeing politely with someone, giving a short presentation to a small team, and eventually speaking to a larger audience. People work up the list at a pace that is challenging but manageable.

Making exposure effective

Research suggests exposure works best when it is repeated regularly, practised in varied contexts and with different people, done without safety behaviors, and approached as an experiment: "What do I predict will happen, and what actually happened?" Focusing attention outward on the conversation, rather than on internal sensations, also helps. Some exercises deliberately involve small social "mishaps", such as asking for directions to a nearby building, to test fears of embarrassment.

Medication Options

Several medications have research support for social anxiety disorder, and a doctor may discuss medication as an option, particularly for people who prefer it, who have not benefited enough from psychological therapy, or who have co-occurring depression. In the Mayo-Wilson (2014) analysis, some classes of antidepressant medication showed benefits over placebo, though individual CBT had larger and more durable effects on average. Some medications are used only for specific performance situations, and some sedating medications are generally discouraged for long-term use because of dependence risks.

All medications have potential side effects, can take several weeks to work, and should not be stopped suddenly without medical advice. Choosing, adjusting or stopping medication is a decision to make with a doctor or psychiatrist. This page does not give medication advice.

Self-Help Strategies

The strategies below draw on CBT principles and are best seen as general supports. Guided self-help based on CBT has research support for mild to moderate social anxiety, but persistent or severe difficulties are best addressed with a professional.

Working with thoughts

Noticing anxious predictions and asking questions such as "What's the evidence?", "What would I say to a friend?" and "How much will this matter next month?" can loosen their grip. Remembering the spotlight effect, the well-documented tendency to overestimate how much others notice us, can also help. Perfect social performance is not required for people to like us. Techniques of cognitive restructuring are explained in more detail on our dedicated page.

Gradual practice

Choosing small, achievable social challenges, practising them regularly, dropping safety behaviors one at a time, and recognising effort rather than perfection can build confidence over time. Volunteering, classes and clubs organised around a shared activity can provide structured opportunities. Our page on social skills offers related ideas.

Managing physical anxiety

Slow breathing, such as box breathing, and progressive muscle relaxation can reduce physical tension. These are most helpful as general calming practices, not as safety behaviors relied on to get through situations.

Self-compassion

Harsh self-criticism after social situations fuels post-event rumination. Practising a kinder, more balanced inner voice, as described in self-compassion practice, may reduce this cycle.

Living with Social Anxiety

At work and school

Social anxiety can affect presentations, meetings, interviews and networking. Gradual practice, preparation that focuses on key points rather than memorised scripts, and support from a manager or teacher can help. In many countries, anxiety disorders can qualify for reasonable adjustments at work or school under disability laws.

Relationships

Social anxiety can make it harder to form friendships and romantic relationships. Many people find that sharing their difficulties with a trusted person brings relief and support. Partners and friends can help by being patient, encouraging gradual steps, and avoiding either pushing too hard or doing everything for the person.

Outlook

Without treatment, social anxiety disorder often runs a long course, and many people wait years before seeking help. With effective treatment, many people improve substantially, and some no longer meet criteria for the disorder. Even when some anxiety remains, people often find it no longer stops them from doing what matters. Our guide to finding a therapist explains how to look for someone trained in CBT.

Conclusion

Social anxiety disorder is a common and often long-lasting condition involving intense fear of being judged, maintained by self-focused attention, safety behaviors, avoidance and rumination. It differs from shyness and introversion and frequently co-occurs with depression and alcohol problems. The good news is that it is well understood and highly treatable: cognitive behavioral therapy, especially cognitive therapy based on the Clark and Wells model, has the strongest evidence, and medication is another option a doctor may discuss. Seeking help earlier can prevent years of missed opportunities.
