The purpose of this paper is to discuss the clinical utility of a dimensional classification of personality disorder. The paper begins with a brief description of the five-factor model of personality disorder, followed by a discussion of three fundamental components of clinical utility: ease of usage, communication, and treatment decisions. It is suggested that the five-factor model compares well to personality disorder diagnostic categories with respect to all three components of clinical utility.
