Avoidant personality disorder and social phobia: distinct enough to be separate disorders?
OBJECTIVE
Existing evidence from anxiety disorder research indicates that social phobics (SP) with avoidant personality disorder (AVPD) experience more anxiety and show more impairment than patients with SP alone. The purpose of this study was to examine whether in patients diagnosed with AVPD, the co-occurrence of SP adds to its severity. We hypothesized that the addition of SP will not add to the severity of AVPD alone.


METHODS
Two groups of patients (AVPD=224; AVPD/SP=101) were compared at baseline and 2 years later on multiple demographic and clinical variables.


RESULTS
Patients with AVPD and an additional diagnosis of SP differed little from patients with AVPD alone.


CONCLUSIONS
These findings suggest that AVPD and SP may be alternative conceptualizations of the same disorder.
