The diagnosis of social phobia.

Humans are social animals attuned to reactions of others; however, some are exquisitely sensitive to--and often misperceive--perceptions of those they encounter. The core feature of social phobia is marked and persistent fear of embarrassment or humiliation in social situations where the individual worries that others may judge his or her performance as too much or too little. Anticipatory anxiety and avoidance occur when the individual is under scrutiny while speaking or performing publicly, eating with others, writing in public, or using public bathrooms. Diagnosis of social phobia is based largely on history obtained from the patient. Onset is usually around puberty; its course is chronic with comorbid depression common and alcohol and other substances routinely abused in misguided attempts to minimize anxiety and depressive symptoms. At examination, patients often have a moist hand, averted gaze, blushing, and other manifest signs of anxiety. Slight shyness is familiar to most, but a substantial number suffer dysfunctional and distressing social anxiety to the point that they become phobic. A few patients satisfy criteria for avoidant personality disorder, which can be socially incapacitating.
