Commentary on Reconceptualizing Personality Disorder Categories Using Trait Dimensions

Authors


Abstract

The ability of trait models of personality to account for categories of personality disorder is examined with particular reference to the five- factor approach. Although dimensional models are consistent with the evidence, and trait models can accommodate personality disorder categories, it is not clear that such models are directly applicable to clinical use. The lower-order or facet structure, in particular, needs further development to capture clinical concepts. It is also suggested that trait models do not account for all aspects of personality disorder—attention also needs to be paid to the organizing and integrative functions of personality.
