Twenty-eight subjects meeting Diagnostic and Statistical Manual of Mental Disorders (rev. 3rd ed.; American Psychiatric Association, 1987) criteria for social phobia and without a comorbid affective disorder and 33 nonclinical controls were asked to present a brief, impromptu speech to a small audience. Speakers themselves, as well as members of the audience, rated each speaker on a public speaking questionnaire that included both specific items (e.g., voice shook) and global items (e.g., appeared confident). For global items, no significant difference was indicated between the two groups on observers' ratings of public speaking performance. However, social phobics rated their own performance worse than did nonclinical controls, and there was a significantly greater discrepancy between self and other ratings for social phobics than controls. Fear of negative evaluation was the only significant predictor of the self-other discrepancy on global items.
