Abstract
Notwithstanding its research and clinical relevance, the dimensionality and validity of the DSM-IV avoidant, dependent, and obsessive-compulsive personality disorders (PDs) criteria is still a largely unexplored topic. The aim of this study was to test the factor structure for DSM-IV Cluster C PD criteria in a sample of 641 consecutively admitted outpatients. Factor analysis results suggested that avoidant, dependent, and obsessive-compulsive PDs share a common latent dimension, and supported the three-factor structure of both observer and self-report ratings of DSM-IV Cluster C PD criteria. The pattern of factor loadings, however, was different from the one expected according to the DSM-IV classification.
