Validation of the dimensional factor structure of the personality psychopathology five in clinical and nonclinical samples.
Confirmatory factor analysis (CFA) was used to determine whether the latent structure underlying the items composing the MMPI-2 Personality Psychopathology Five scales (PSY-5; Harkness, McNulty, & Ben-Porath, 1995) is representative of the theoretical model that informed their construction. Results from the CFA revealed a good fit between the hypothesized five-factor model and the obtained latent factor structure in both clinical (n = 284) and nonclinical (n = 351) samples. Moreover, the PSY-5 model proved to be a better fit than a random five-factor model and a one-factor model. Correlations between the PSY-5 scales and a set of MMPI-2 (DSM-IV) personality disorder scales provided additional evidence of convergent and discriminant validity.
