An examination of syndromal validity and diagnostic subtypes in social phobia and panic disorder

, : An examination of syndromal validity and diagnostic subtypes in social phobia and panic disorder. Journal of Clinical Psychiatry 53(1): 23-27

Background: We investigated whether patients with DSM-III-R panic disorder and patients with social phobia could be distinguished on the basis of selected demographic variables and by several commonly used anxiety and phobia rating scales. Method: Sixty-six patients with social phobia and 60 patients with panic disorder (42 with and 18 without agoraphobia) were studied. Subjects completed a battery of self-report measures that assessed phobic fears, avoidance, and related problems. Results: Social phobic patients showed an earlier age at onset than the panic disorder group, and there was a trend for more social phobics to have never married. Social phobics reported significantly greater levels of social phobic avoidance and distress, fear of negative evaluation, and avoidance of social situations than the panic disorder patients who reported mroe overall anxiety and rated themselves as significantly more avoidant of situations involving exposure to public places and to blood or injury. Discriminant function analysis showed that social phobic and panic disorder patients can be reliably discriminated on these scales. Conclusions: The results of this study lend further support for the validity of the DSM-III-R nosologic distinctions between social phobia and panic disorder. Furthermore, generalized social phobia appears to be remarkably different from discrete social phobia on these measures. This study provides less support for considering panic disorder with agoraphobia to be distinct from panic disorder without agoraphobia.
