Abstract
Dimensional scores were computed for the 11 DSM-3 personality disorders (PDs) in 797 relatives of psychiatric patients and never ill control subjects interviewed with the Structured Interview for DSM-III Personality Disorders. The distribution of scores for all 11 PD dimensions was skewed to the right. A principal components analysis with varimax rotation produced three factors that closely corresponded to DSM-III's suggested clustering of the PDs into eccentric, dramatic, and anxious types. Men scored significantly higher on the paranoid, schizoid, compulsive, antisocial, and narcissistic dimensions, whereas women had significantly higher histrionic, dependent, and avoidant scores. Age was negatively correlated with most of the PD dimensions, and the correlations were strongest with the four PDs in cluster 2 (histrionic, antisocial, narcissistic, and borderline). Each of the eight axis I disorders examined was associated with increased axis 2 pathology.
