The 1994 edition of this title has provided a resource for both researchers and clinicians interested in the applications of the five-factor model to personality disorders. Since the publication of the first edition, a steady flow of empirical research has been conducted, and key theoretical developments have occurred. This revised second edition updates the book and offers nine new chapters. Additional new chapters cover: the history and conceptual background of the FFM; five-factor translations of DSM-III-R and DSM-IV personality disorders; empirical findings on the structure and symptomatology of personality disorders from the five-factor perspective; and application of the FFM to a variety of patient populations among others.
