title: Validation of the dimensional factor structure of the personality psychopathology five in clinical and nonclinical samples.
abstract: 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.
