The Personality Inventory for DSM-5 (PID-5) was created to aid a trait-based diagnostic system for personality disorders (PDs) in the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5; American Psychiatric Association, 2013a). In the present study, we aimed to evaluate the Norwegian version of the PID-5 by examining its score reliability, hierarchical structure, congruency with international findings, and cross-cultural measurement invariance with a matched U.S. sample. For this purpose 503 university students (76% females, Mean age 25.4 years) were administered the PID-5. The Norwegian PID-5 showed good score reliability and structural validity from one to five factors. The five-factor structure was generally congruent with international findings, and support for measurement invariance across the Norwegian and a matched U.S. sample was found. Conclusively, the results indicate that the Norwegian PID-5 has sound psychometric properties, which are substantially comparable with the original U.S. version, supporting its use in a Norwegian population.
