Discriminant validity of the ZKPQ in a sample meeting BPD diagnosis vs. normal-range controls.
Widiger and Simonsen (2005) state that given the limitations of the categorical model of Personality Disorders classification proposals are to be expected for dimensional classifications. The purpose of this paper is to test the alternative five factorial model (AFFM) of personality in a sample with PDs. Subjects were administered the ZKPQ to test the discriminant capacity of the AFFM in classifying subjects diagnosed with BPD (n = 74) vs normal-range controls (n = 148) paired by age and sex, and identifying sensitive and/or specific dimensions that can be of help in diagnosing BPD. The results showed that high scores on N-Anx and Imp-SS, and low scores on Act are prognostic factors for being diagnosed with BPD. Likewise, this model correctly classified 88% of subjects with a kappa index of 0.73. The AFFM of personality appears to have a substantial power for predicting SCID-II interview-based BPD diagnosis.
