The validity of Cloninger's psychobiological model versus the five-factor model to predict DSM-IV personality disorders in a heterogeneous psychiatric sample: domain facet and residualized facet descriptions.
The validity of Cloninger's psychobiological model and the Five-Factor Model of personality to predict DSM-IV personality disorders was examined in a psychiatric in-patient sample of 130 individuals. Patients completed Dutch authorized versions of the TCI (Cloninger, Svrakic, & Przybeck, 1993) and the NEO PI-R (Costa & McCrae, 1992) and were also administered the ADP-IV (Schotte & De Doncker, 1994), a Dutch self-report questionnaire to assess Axis-II disorders. No personality-descriptive model proved to be superior in explaining personality disorder symptoms at the higher-order level: the TCI dimensions better explained the Obsessive-Compulsive and the Narcissistic disorders, whereas the FFM accounted for more variance of the Avoidant disorder. However, differences were apparent at the lower-order level with the NEO facets out performing the TCI subscales for six to four personality disorders. FFM facet-level predictions of Widiger, Trull, Clarkin, Sanderson, and Costa (2002) were partially confirmed, with substantially better results using residualized facet scores. A set of TCI subscale personality disorder relationships is suggested.
