Social anxiety disorder

**Definition:** Social anxiety disorder is characterised by marked and excessive fear or anxiety that consistently occurs in one or more social situations such as social interactions (e.g. having a conversation), doing something while feeling observed (e.g. eating or drinking in the presence of others), or performing in front of others (e.g. giving a speech). The individual is concerned that he or she will act in a way, or show anxiety symptoms, that will be negatively evaluated by others. Relevant social situations are consistently avoided or else endured with intense fear or anxiety. The symptoms persist for at least several months and are sufficiently severe to result in significant distress or significant impairment in personal, family, social, educational, occupational, or other important areas of functioning.
