PREVALENCE OF PERSONALITY-DISORDERS AMONG PATIENTS WITH ANXIETY DISORDERS

Outpatients with a principal diagnosis of an anxiety disorder (n = 347) were administered the Structured Clinical Interview for DSM-III-R/Axis II Disorders (SCID-II) during their intake evaluation. At least one personality disorder was found in 35% of these patients. Patients with social phobia (61%) and generalized anxiety disorder (49%) were most often diagnosed with a personality disorder. Patients with simple phobia were rarely diagnosed with a personality disorder (12%). The most commonly diagnosed personality disorders were from the ''anxious/fearful'' cluster (27% received at least one diagnosis from cluster C), most notably avoidant and obsessive-compulsive personality. Our findings suggest that personality disorders, in general, are less prevalent among anxious patients than among depressive patients.
