The utility of the DSM personality disorder (PD) system remains a concern. The strategy employed represents one approach designed to evaluate and improve the diagnostic efficiency of the SCID-II PDs. Using a sample of 203 patients, SCID-II PD items - based on the criterion sets of the 10 DSM-IV PDs - were evaluated with respect to (a) convergent validity; (b) divergent validity; (c) relation to general personality traits; and (d) association with functional impairment. Only Borderline PD items were satisfactory on all four evaluation criteria. Histrionic and Obsessive-Compulsive PD items met criteria for convergent and divergent validity and relation to personality dimensions of the Five-Factor Model of Personality (FFM) but were not related to functional impairment, suggesting they might be reconsidered as disorders. Schizotypal PD items met three of the four criteria but showed no relation to FFM dimensions, suggesting that it may be a candidate for reassignment to Axis I.
