Social anxiety disorder: symptoms, diagnosis, and treatment

Social anxiety disorder (also known as social phobia) is a common and treatable anxiety disorder characterized by an intense fear of being judged, negatively evaluated, or embarrassed in social or performance situations. A proper social anxiety disorder diagnosis is important to distinguish these symptoms from normal nervousness or shyness.

According to the DSM-5-TR, social anxiety disorder involves a persistent fear of situations in which a person is exposed to possible scrutiny by others. This includes situations such as conversations, meeting unfamiliar people, being observed (e.g., eating or writing), or performing in front of others (e.g., presentations or interviews).

The core fear is not the situation itself, but the possibility of negative evaluation, for example, appearing anxious, saying something wrong, or being perceived as incompetent. As a result, many individuals either avoid these situations or endure them with intense anxiety.

In clinical practice, social anxiety often presents as a pattern of avoidance and safety behaviours, such as over-preparing, avoiding eye contact, mentally rehearsing conversations, or relying on others for reassurance. While these strategies reduce anxiety in the short term, they maintain the problem over time and are often identified during a social anxiety disorder diagnosis.

Without treatment, social anxiety can interfere with relationships, career opportunities, and overall quality of life. However, with structured and evidence-based treatment, significant improvement is highly achievable.

DSM-5-TR criteria for social anxiety disorder

The following criteria are based on the Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR), which is the current standard used by clinicians to diagnose social anxiety disorder.

A diagnosis requires a consistent pattern of fear, avoidance, and distress that significantly interferes with daily functioning.

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). Giving a speech in front of an (unknown) audience can be very stressful and produce physical symptoms, such as a dry mouth, trembling or shaking, sweating, numbness or tingling, feeling faint or dizzy, chest pain, shortness of breath, heart palpitations and accelerated heartbeat. Someone with social anxiety disorder usually is afraid that the audience will see these physical symptoms, which is embarrassing or humiliating for the person with social anxiety disorder.

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). These fears increase physical symptoms, which in turn reinforce the anxiety.

C. The social situations almost always provoke fear or anxiety. Experiencing some distress, worry and a few physical symptoms is normal on a first date or public speech. However, experiencing fear or anxiety every time an individual encountering situations described in criterion A, is not healthy.

D. The social situations are avoided or endured with intense fear or anxiety. People do not like anxiety and try to avoid feared situations as much as possible. If they cannot avoid these situations, they usually endure the feared situation with intense anxiety and distress. Critical note: sometimes an individual has one or more safety behaviors or objects to reduce their anxiety levels. A safety behaviour refers to any action, object, or person used to reduce anxiety. An example could be taking a best friend to a meeting or keeping deodorant in a purse.

E. The fear or anxiety is out of proportion to the actual threat posed by the social situation and to the sociocultural context. If someone responds out of proportion to the actual threat, it may indicate difficulty coping with certain situations. If responses are in line with those of others, it’s a clear sign that the individual can cope with the situation in a healthy way.

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

G. The fear, anxiety, or avoidance causes clinically significant distress or impairment
in social, occupational, or other important areas of functioning. Someone with social anxiety disorder may avoid parties and social gatherings and miss out on some things. It is also possible that an individual with social anxiety avoids speeches at work and consequently misses out on a promotion.

H. The fear, anxiety, or avoidance is not attributable to the physiological effects of a substance (e.g., a drug abuse or a medication) or another medical condition. Some drugs or medications produce side effects similar to those of social anxiety: trembling or shaking, heart palpitations, sweating, feeling more anxiety. In order to diagnose someone with social anxiety disorder, it is important to rule out side effects of drugs and medications.

I. The fear, anxiety, or avoidance is not better explained by symptoms or another mental disorder, such as panic disorder, body dysmorphic disorder, or autism spectrum disorder. Some mental disorders have overlapping symptoms. For instance, sleeping problems are common in depression, but also in PTSD. Ruling out other mental disorders is therefore important.

J. If another medical condition (e.g., Parkinson’s disease, obesity, disfigurement from burns or injury) is present, the fear, anxiety, or avoidance is clearly unrelated or is excessive. In other words: the social anxiety disorder symptoms cannot be (better) explained by another medical condition.
