The Brief Social Phobia Scale.

An observer measure of social phobic symptoms, referred to as the Brief Social Phobia Scale, consists of 11 items, 7 evaluating commonly feared or avoided situations and 4 additional items measuring autonomic distress. Symptoms represented by the scale items are found frequently in social phobia, and the instrument demonstrates acceptable interrater and test-retest reliability, internal consistency, concurrent validity against other measures of social phobia, and the ability of patients to change as a result of treatment. It can also detect differences between active treatment and placebo treatment. A comparison of the sensitivity of this scale with other scales in detection of size of effect also is presented.
