A search for consensus on the dimensional structure of personality disorders.

Previous attempts to elucidate the dimensional structure of personality disorders (PDs) have been based on single samples and measures. Like one-item tests, they are useful but scattered and potentially misleading glimpses at the true structure of PDs. Therefore, reanalyses of 33 previously published data sets were conducted using recommended statistical procedures to arrive at consensus structures. Similar reanalyses of published data were conducted on associations between PDs and the five-factor model of normal personality characteristics. High degrees of congruence were observed between the consensus PD structures and the consensus structures suggested by dimensions of normal personality. The analytic techniques used in the present study helped bypass methodological problems inherent in previous tests and revealed higher levels of support for both theoretically and empirically based representations of the five-factor model approach to PDs. 2004 Wiley Periodicals, Inc.
