Abstract

The present study aimed to examine the utility of the Minnesota Multiphasic Personality Inventory-3 (MMPI-3) in the assessment of personality disorders (PDs). Data were extracted from a larger study on eating behaviors and personality. Subjects included undergraduate students at Sam Houston State University who were administered the MMPI-2-Restructured Form-Extended Battery (MMPI-2-RF-EX) and the Personality Inventory for the DSM-5-Short Form (PID-5-SF) as a measure of dimensional pathological personality traits. First, we examined associations between the MMPI-3 and the Alternative Model for Personality Disorders (AMPD) of the DSM-5 and ICD-11 personality trait model, as measured by the PID-5-Short Form. In addition, we examined captured variance of the PID-5-SF domain scales by the MMPI-3 Personality Psychopathology-5 (PSY-5) Scales. Finally, we examined the joint factor structure of the MMPI-3 PSY-5 scales and the PID-5-SF trait facets. Results suggested MMPI-3 scales were largely convergent with both the PID-5 domain and facet scores and ICD-11 domain scales, with the exception of Anankastia. Further, results supported the convergence of the PSY-5 scales with both the AMPD and ICD-11 trait models in particular. The results provide a necessary update to personality assessment with the MMPI-3 and provides further insight into the use of the MMPI instruments in assessing personality psychopathology in the AMPD and ICD-11 models.
