Investigating the Relationship Between DSM-5 Personality Disorder Domains and Facets and Aggression in an Offender Population Using the Personality Inventory for the DSM-5.

This study explored associations between aggression and the Personality Inventory for the DSM-5 (PID-5) domains and facets in 208 male offenders. Regression analyses revealed no significant domain-level relationships using either the APA-three facets only (Krueger, Derringer, Markon, Watson, & Skodol, 2013) or the Krueger, Derringer, Markon, Watson, and Skodol (2012) scoring algorithms. The PID-5 facets of Hostility and Risk Taking were significantly associated with aggression. These findings highlight the importance of a facet-level analysis when exploring the PD-aggression relationship. The authors call attention to how this knowledge can contribute to clinical-forensic practice and note limitations associated with using only PID-5 domain-level scoring approaches. More research is required to determine whether a universally accepted scoring approach can be adopted and promoted alongside future versions of the PID-5.
