Social Anxiety Disorder

Social anxiety disorder is an intense, persistent fear of being watched, judged, or embarrassed in social situations. It goes beyond normal shyness.

Nervousness before a big event is common and short-lived, but social anxiety disorder is pervasive, out of proportion to any real threat, and can significantly disrupt daily life.

Many people experience some anxiety in certain social situations, such as going to a job interview or giving a speech at a wedding. It is normal to expect to feel nervous or worried about such situations.

For people with social anxiety, though, these feelings occur in most or all social situations. It rarely fades on its own.

What is Social Anxiety?

Social anxiety disorder, also known as social phobia, is an anxiety disorder characterized by intense fear and anxiety in social situations.

They may experience social anxiety at school, at work, at social events, and in public.

Social situations can feel so distressing that they avoid or escape them entirely, just to sidestep their fears.

Below is a list of some of the social situations that someone with social anxiety disorder may find challenging:

• Public speaking
• One-on-one conversations
• Social events, e.g., parties
• Meeting new people
• Making phone calls
• Job interviews
• Giving presentations
• Work meetings
• Eating or drinking in front of people
• Talking to authority figures

How Common Is Social Anxiety?

Social anxiety disorder is one of the most common anxiety disorders. Most people feel shy sometimes, but only around 12% of US adults who call themselves shy meet the full diagnostic criteria for social anxiety disorder (American Psychiatric Association, 2022).

Who Is Most Likely to Develop It?

A large US study estimated a lifetime prevalence of about 12.1%, making social anxiety disorder the second most common anxiety disorder (Kessler et al., 2005).

The disorder typically begins in childhood or early teens. Most cases are established well before someone turns 20 (Kessler et al., 2005).

One seven-country study of young people found a substantial share of 16-to-29-year-olds met the criteria for social anxiety, though rates varied by country (Jefferies & Ungar, 2020).

The reasons for this are not fully clear.

Social anxiety is more common in women than men in the general population, though this gap narrows, or even reverses, among people who seek treatment. This pattern may reflect gender differences in help-seeking, rather than true differences in how common the disorder is (American Psychiatric Association, 2022).

Recent Prevalence Estimates

Recent US research puts the yearly rate at 7%.

Rates are much lower through most of the rest of the world, at roughly 0.5% to 2% (American Psychiatric Association, 2022).

The reasons are debated.

Prevalence appears to be rising in the United States and East Asian countries specifically. This looks like a genuine trend, not simply better measurement (American Psychiatric Association, 2022).

Onset before adulthood is common enough that early support could change a person’s school and work trajectory.

The Cost of Untreated Social Anxiety

The costs are real.

Social anxiety disorder is linked to higher school dropout, lower work productivity, and a greater chance of remaining single or unemployed (American Psychiatric Association, 2022).

For men, this often means staying single or childless; for women, it is more often linked to unemployment (American Psychiatric Association, 2022).

The impact goes beyond discomfort.

People with social anxiety disorder often say their friendships feel less close and less supportive than those of their peers (American Psychiatric Association, 2022).

Despite this impact, only around half of people with the disorder in wealthy countries ever seek treatment. They typically wait 15 to 20 years after symptoms begin (American Psychiatric Association, 2022).

Signs Of Social Anxiety

People with social anxiety may experience a combination of cognitive, behavioral, and physical signs.

Cognitive signs

Cognitive signs of social anxiety are usually negative beliefs, biases, and thoughts about oneself or social situations, and can include the following: 

• Intense anxiety during social situations
• Fear of talking to strangers
• Fear of situations where there is the possibility of being negatively judged
• Fear that others will notice the anxiety
• Fear of physical sensations associated with anxiety
• Overthinking social interactions after they have ended
• Misreading people’s emotions as social rejection

Behavioral signs

Socially anxious individuals often act in specific ways because of their anxiety. These behavioral signs include:

• Avoiding speaking
• Avoiding being the center of attention
• Leaving or escaping social situations
• Using safety behaviors (e.g., scrolling on a phone)
• Missing school or work

Physical signs

Physical signs typically appear before, during, and after a social situation. These reflect the body’s fight or flight response and include:

• Blushing
• Sweating
• Rapid heartbeat
• Nausea
• Feeling breathless
• Light-headedness
• Muscle tension

These signs vary widely: some people experience only a few, while others experience many more. Social anxiety looks different for everyone.

What Does Social Anxiety Feel Like? 

Below are some quotes from experts and individuals who have experienced social anxiety, who describe what it really feels like.

What does an expert say?

Therapist Angela Dierks describes how she has encountered clients with social anxiety who experience a lot of shame:

‘Very often, somebody with social anxiety is not very shame-resistant. They’re very shame-prone. They’re very likely to experience the (signs of) flushing cheeks and going red in the face as being deeply shameful.’

Dierks goes on to explain how egocentricity (the excessive focus on oneself) plays a big role in many people with social anxiety:

‘You become quite egocentric when you are anxious… there’s this sense that the whole world is paying attention to you, that people are paying intense attention to you. That people notice every single emotion that you might be experiencing… The truth is often that most people wouldn’t notice. They don’t know exactly what’s going on for you. They may not even be that interested.’

Personal experiences of social anxiety

In a study by Mohammadi et al. (2019), one participant described how restricting social anxiety can feel:

‘When I am in stressful situations I can’t speak or move, it is like I am in a cage.’

People who have experienced social anxiety often describe feeling powerless or unworthy in social situations: 

‘I think something makes me most vulnerable in these situations and that is I don’t feel worthy enough.’

From Mohammadi et al. (2019)

This feeling was shared by Kate when she described her personal experience: 

‘but I think that’s a lot of what social anxiety is is feeling out of control and like you don’t have the power in a conversation or don’t have the power to hold a conversation.’

Likewise, some people with social anxiety cope by over-preparing for social situations, as Ryan describes:

‘My social anxiety really stemmed from not knowing what to say. And I found that I would be planning dialogue in my head before having a conversation with somebody. And I would always try to be like two or three steps ahead of the conversation.’

What Causes Social Anxiety?

The exact causes of social anxiety are not fully understood, but there are several factors that may contribute to its development.

Overall, social anxiety is likely caused by a combination of genetic, environmental, and biological factors.

Can I inherit social anxiety from my family?

Genetics play a role. But what is inherited is best understood as a temperament, not social anxiety itself. The strongest evidence points to behavioral inhibition, an early tendency to react to unfamiliar people and situations with wariness and withdrawal.

One study quantified this link. A meta-analysis of seven studies found behavioral inhibition in childhood was linked to a sevenfold increase in the odds of developing social anxiety disorder (Clauss & Blackford, 2012).

Around 15% of children show extreme behavioral inhibition, and nearly half of these go on to develop the disorder.

What are some possible biological causes of social anxiety?

Studies have suggested that imbalances of the neurotransmitters serotonin and dopamine could play a role in developing social anxiety.

One study, for instance, found increased serotonin and dopamine activity in brain regions associated with fear (the amygdala) and rewards (the nucleus accumbens). Greater activity in these regions was correlated with symptom severity (Hjorth et al., 2019).

Imaging studies support this link. People with social anxiety disorder show selective amygdala activation when exposed to fear-relevant stimuli (Birbaumer et al., 1998).

Others show differing patterns of amygdala activation during aversive conditioning (Schneider et al., 1999).

That distinction matters. These brain-based findings fit well with a temperamental explanation for social anxiety. But biology alone does not explain why the fear is specifically about being judged, rather than a general fear response.

For that, psychological explanations of how the mind processes social situations are still needed.

Can environment and life events cause social anxiety?

Environmental influences also play a role. Stressful life events, such as challenges at work, school, or traumatic experiences, may trigger onset.

Early learning experiences are important as well: children raised in overly critical, controlling, or protective households may be more likely to develop anxiety.

Parents who are themselves anxious may unintentionally pass on these worries, modeling social fears for their children.

“I was raised in a family full of tension and stress that were beyond my ability to manage.”
— Interview extract from Mohammadi et al. (2019)

Many people with social anxiety recall being shy or withdrawn as children. Bullying or abuse can reinforce this vulnerability, making social fears more persistent.

Finally, social isolation and loneliness have also been linked to the development of social anxiety (Eres et al., 2023).

How Is Social Anxiety Disorder Diagnosed?

Mental health professionals diagnose social anxiety disorder using standard criteria, most often from the DSM-5 or ICD-11.

Diagnostic Criteria

These frameworks describe the condition as a persistent and intense fear of being judged in social situations, lasting at least six months, and significantly interfering with daily life.

Some people fear only performance situations, such as public speaking.

This performance-only form often responds to more targeted treatment, such as a beta-blocker before a specific event, while the more common generalized form benefits from full psychological treatment.

The fear must also be out of proportion to any real threat, and the situations must reliably trigger anxiety. They avoid these situations, or endure them with real distress.

A clinician must also judge that the difficulties are not better explained by another condition, substance, or medical problem.

This distinguishes the disorder from ordinary nervousness, which does not meet these thresholds.

The Diagnostic Process

The process begins with a clinical interview. A professional asks when symptoms began, how often they occur, and how they affect areas such as school, work, or relationships.

A physical exam may follow, to rule out medical issues that could mimic or worsen anxiety.

To support the interview, clinicians sometimes use structured questionnaires that measure severity and track change over time, including:

• The Liebowitz Social Anxiety Scale (LSAS)
• The Social Phobia Inventory (SPIN)

These tools are not diagnostic on their own.

Diagnosis also involves differential diagnosis: ruling out other conditions with overlapping features, such as generalized anxiety disorder, depression, body dysmorphic disorder, or autism.

This ensures the difficulties are best explained by social anxiety disorder, rather than another condition.

What Keeps Social Anxiety Going?

Social anxiety often persists because people overestimate the likelihood that something will go wrong and the cost of what might happen if it does.

For example, when giving a presentation, someone may believe it is very likely they will stutter (probability) and that classmates will laugh or judge them harshly if it happens (cost). These thoughts heighten anxiety and can trigger physical symptoms like trembling, blushing, or nausea.

Many individuals also worry about the visibility of these symptoms, fearing they will appear anxious, boring, or incompetent, which in turn reinforces the cycle (Hofmann et al., 2010).

Research shows perfectionism plays a role as well. Those with perfectionistic tendencies set unrealistically high standards, criticize themselves harshly, and fear negative evaluation, which can intensify social anxiety (Ferber et al., 2024).

Attempts to project an image of flawlessness often backfire, increasing self-consciousness and fueling more anxiety.

Other maintaining factors include:

• Hypervigilance to “social threats”
• Negative self-beliefs
• Fear of “social catastrophe”
• Self-focused attention
• Avoidance and safety behaviors
• Concerns about how others perceive them
• Deeply held core beliefs

As David Clark, the Oxford psychologist who co-developed the leading model of social anxiety, explains, socially anxious people shift their attention inward when entering a feared situation.

This shift is called self-focused attention: monitoring physical sensations like a racing heart, rather than watching what is actually happening around them.

The resulting image is rarely accurate.

Because attention is absorbed inward, the person builds a distorted mental picture of how they appear, usually far worse than reality. They rarely take in the actual feedback that could correct it.

Safety behaviors make this worse. Avoiding eye contact or over-rehearsing what to say can prevent someone from ever discovering that the feared outcome would not have happened (Clark & Wells, 1995).

Avoidance Behaviors in Social Anxiety

People with social anxiety often cope by avoiding feared situations, such as meeting new people, speaking in groups, or attending school or work. This brings short-term relief.

But it reinforces anxiety in the long run, because it stops people from testing their fears or gaining positive experiences.

Avoidance can limit personal and professional opportunities, lower self-esteem, and contribute to isolation or depression.

When unavoidable social situations do arise, anxiety can feel even more overwhelming, because there has been no practice or preparation.

Steps Toward Reducing Avoidance

Overcoming avoidance is a gradual process, and small steps can make a meaningful difference. Helpful strategies include:

• Start small: Choose a mildly uncomfortable situation rather than the most intimidating one.
• Set achievable goals: Break larger challenges (e.g., giving a presentation) into smaller steps, such as practicing with a friend.
• Notice patterns: Keep track of when avoidance shows up and what thoughts fuel it.
• Reward progress: Acknowledge even minor efforts, such as attending a social event briefly.

These steps don’t eliminate anxiety overnight, but over time they can build confidence and reduce the cycle of avoidance.

Safety Behaviors in Social Anxiety

When avoidance isn’t possible, individuals may rely on safety behaviors to ease discomfort.

These include speaking quietly, planning dialogue in advance, avoiding eye contact, wearing inconspicuous clothing, or using alcohol and drugs.

These behaviors may reduce anxiety temporarily. But they maintain the cycle, because they prevent people from discovering that feared outcomes rarely occur. Reliance on them can even worsen anxiety over time and create new problems, such as embarrassment from alcohol use.

Like avoidance, safety behaviors shift focus inward and away from genuine engagement. This reinforces self-consciousness and blocks opportunities for growth.

Steps Toward Reducing Safety Behaviors

Letting go of safety behaviors can feel challenging, but gradual changes help individuals test fears and build confidence. Some useful approaches include:

• Experiment gradually: Try easing up on one safety behavior at a time, such as maintaining brief eye contact or speaking slightly louder.
• Test predictions: Notice what actually happens when a safety behavior is reduced. Outcomes are often less negative than expected.
• Shift focus outward: Concentrate on the conversation or activity, rather than monitoring how you appear.
• Reflect afterward: Write down what went well to counter anxious thoughts and reinforce progress.

These small experiments can help reveal that feared consequences are often unlikely, reducing reliance on safety behaviors over time.

How Is Social Anxiety Treated?

Research shows that the most effective approaches for social anxiety disorder often combine psychological therapies, lifestyle strategies, and, in some cases, medication.

Therapies

Mental health professionals frequently recommend cognitive-behavioral therapy (CBT), which helps individuals identify and reframe negative thought patterns.

A related method, exposure therapy, involves gradually and safely facing feared social situations to reduce avoidance and build confidence over time.

Other approaches, such as mindfulness-based strategies and social skills training, have also shown benefits.

The evidence for cognitive therapy is strong. In one major trial, 62 people with social phobia were randomly assigned to cognitive therapy, exposure therapy, or a waiting list (Clark et al., 2006).

After treatment, 84% of the cognitive therapy group no longer met the criteria for social phobia, compared with 42% for exposure therapy and 0% for the waiting list. Cognitive therapy’s advantage held a year later.

Lifestyle Approaches

Complementary strategies, such as relaxation techniques (e.g., deep breathing, meditation), regular exercise, and adjustments like improving sleep or reducing caffeine and alcohol intake, may support recovery.

These methods are often used alongside therapy rather than as stand-alone treatments.

Medication

In some cases, clinicians may prescribe medications to help manage symptoms. Selective serotonin reuptake inhibitors (SSRIs) are the first-line medication for social anxiety disorder, while beta-blockers are sometimes used for performance-related anxiety.

These options are tailored to individual needs and always managed by qualified healthcare professionals.

Support Systems

Support groups, whether in-person or online, can also provide encouragement and a sense of connection.

Treatment plans are often individualized, combining different approaches based on severity, goals, and preferences.

Critical Evaluation

Social anxiety disorder’s leading account is a cognitive model, and decades of research have tested both its strengths and its limits.

• Strong treatment leverage: The self-focused-attention model explains why sufferers feel intensely judged even when they perform well, and it has been turned directly into effective treatments (McManus et al., 2009).
• Converging evidence: An early, measurable temperament (behavioral inhibition) and heightened amygdala reactivity together give the disorder a coherent, biologically grounded explanation.
• Overlap with avoidant personality disorder: Where ordinary shyness ends and social anxiety disorder begins is debated, and the disorder overlaps heavily with avoidant personality disorder.
• Comorbidity and cause: Social anxiety disorder frequently occurs alongside depression and other anxiety disorders, and much of the evidence linking childhood adversity to it is correlational, not experimental.
• Cultural specificity: The diagnostic criteria have shifted with cultural critique, such as adding a fear of offending others, showing the disorder’s boundary is partly culturally shaped.

Contemporary Research

Research since 2014 clarifies which treatment works best, and whether effective care can reach more people.

Which Treatment Works Best?

A large review combined 101 trials of more than 13,000 adults with social anxiety disorder, comparing 41 psychological, medication, and self-help treatments within one framework (Mayo-Wilson et al., 2014).

Individual cognitive therapy produced the largest effect of any treatment and was one of the few options to beat a credible placebo. SSRIs and SNRIs were the most consistent medications.

Individual cognitive-behavioral therapy is therefore the best first-line treatment, with SSRIs the preferred option for those who decline psychological therapy.

A related cost-effectiveness analysis reached the same conclusion, ranking individual cognitive therapy the most cost-effective option overall (Mavranezouli et al., 2015).

Making Treatment Accessible

Because individual cognitive therapy works well but needs a trained therapist, researchers have tested internet-delivered versions instead.

One trial tested this directly. A group of 103 young people aged 10 to 17 were randomly assigned to guided internet-delivered CBT or internet-delivered supportive therapy for ten weeks.

Assessors were kept unaware of which group each young person was in (Nordh et al., 2021).

The results were clear. Internet-delivered CBT was significantly more effective than the active comparator three months later.

It also saved money through lower medication costs and better school attendance.

This approach works. Guided internet-delivered CBT is effective and cost-effective for youth social anxiety, and could widen access to care by economizing on scarce therapist time.

This effect held up when the same programme was delivered by local therapists in Hong Kong, suggesting it travels well across cultures (Thew et al., 2022).

Newer Research Directions

Standard treatment says little about shame.

A 2026 study followed 72 adults with social anxiety through eight sessions of either cognitive therapy or a newer technique, imagery rescripting. This newer approach works directly on painful childhood memories, rather than on current thoughts (Winter, Norton, & Wootton, 2026).

The results were striking.

Both treatments produced large drops in shame, even though neither directly targeted it. This suggests reducing shame may be an important, if currently accidental, ingredient of effective treatment.

This matters for treatment.

A separate 2025 pilot trial tested a different angle: a group programme that builds everyday social connections, rather than treating anxiety directly. Thirty-three adults with high social anxiety completed the five-module programme (Donaldson et al., 2025).

The findings were promising.

Loneliness fell sharply, and social anxiety symptoms also fell significantly, even though the programme never targeted anxiety directly. As an uncontrolled pilot with no comparison group, it cannot prove the programme caused the improvement, but it is a promising early lead.
