Comparison of personality disorders in different anxiety disorder diagnoses: panic, agoraphobia, generalized anxiety, and social phobia.

ABSTRACT

Recently there has been increasing interest in the relationship of the personality and the anxiety disorders. This paper presents comorbidity findings between DSM-III-R personality pathology and several DSM-III-R anxiety disorders and makes direct comparisons between anxiety groups. This is the most extensive comparison of this kind reported thus far. This report is on the first 475 anxiety patients who were recruited from multiple sites to take part in a naturalistic study of anxiety. All had a DSM-III-R diagnosis of panic, agoraphobia, social phobia, or generalized anxiety disorder (GAD). Previous studies which found a high comorbidity between the anxiety and the personality pathology were confirmed, with a significantly higher prevalence of personality pathology occurring with social phobia and GAD. Among our patients, all of whom had anxiety disorders, the presence of comorbid major depression is associated with an increase in the levels of comorbid personality pathology--as previously described in the literature. The relationship between low social functioning and the presence of personality pathology was confirmed, however, the relationship appears to be specific to certain areas of functioning, a new finding. There is a clinically important relationship between Personality Diagnostic Questionnaire--Revised personality pathology and the anxiety disorders characterized by different prevalences of personality disorders in different anxiety disorders and specific areas of social dysfunction.
