Social anxiety disorder (SAD), also known as social phobia, is a common disorder characterized by excessive fears of scrutiny, embarrassment, and humiliation in social or performance situations, leading to significant distress or impairment in functioning.

SAD is a prevalent condition, estimated to affect between 3 and 7 percent of the adult United States population over a 12-month period. SAD typically begins in childhood or adolescence and, untreated, can be associated with the subsequent development of major depression, substance abuse, and other mental health problems. The disorder can be associated with extensive functional impairment and reduced quality of life [1].

This topic addresses the epidemiology, pathogenesis, clinical manifestations, and diagnosis for SAD. Psychotherapy and pharmacotherapy for the disorder are discussed separately. (See "Psychotherapy for social anxiety disorder in adults" and "Pharmacotherapy for social anxiety disorder in adults".)


Behavioral inhibition — A childhood temperament that has been operationally defined by researchers to refer to young children who manifest fear and withdrawal behavior when introduced to novel situations or unfamiliar persons.

Avoidant personality disorder — An avoidant personality disorder is described in DSM-5 as a pervasive pattern of social inhibition, feelings of inadequacy, extreme sensitivity to negative evaluation, and avoidance of social interaction [2].
