The relationship of social phobia subtypes and avoidant personality disorder.

The diagnoses of social phobia (SP) and avoidant personality disorder (APD) have evolved from different historical sources, but their criteria appear to converge in DSM-III-R. Fifty anxiety disorder clinic patients with DSM-III-R SP were evaluated for presence of DSM-III-R APD. APD was present in 89% of those with the generalized subtype of SP (GSP) and 21% of those with the discrete subtype of SP (DSP). The findings are discussed in conjunction with other recent reports showing substantial overlap between GSP and APD.
