Replicating the five factor model of personality in a psychiatric sample

In this study we examined whether the factor structure and traits of the five-factor model of personality (FFM), derived from non-clinical samples, could be replicated in a sample of psychiatric patients. The revised NEO Personality Inventory (NEO PI-R) was administered to a study group of psychiatric patients (n=176). The test scores from these patients were intercorrelated, factor analyzed and the obtained factor structure was then compared to the factor structure of the normative data from the NEO PI-R. The factor structure from the psychiatric study group and that from the normative sample were virtually identical, with all five factors showing significant congruence. These results argue favorably for the clinical applicability of the FFM with psychiatric patients. © 1999 Elsevier Science Ltd.
