Convergent and Discriminant Validity of Personality Inventory for DSM-5-BF in a Primary Care Sample.

A growing body of research supports the validity of the Personality Inventory for DSM-5 (PID-5) in evaluating community and psychiatric samples. Although maladaptive personality also has significant relevance in primary care settings, research on the PID-5 in primary care samples is limited. In this study, the authors examined the intercorrelations, convergent validity, and discriminant validity of the brief form of the PID-5 (PID-5-BF) in 100 primary care outpatients. Results are consistent with findings in other samples in suggesting that PID-5 domains are moderately intercorrelated and associated with a variety of mental health variables. Smaller associations with physical health variables support the discriminant validity of the instrument. Overall, results suggest that the PID-5-BF can provide a useful psychiatric screening tool in primary care settings.
