The current study aimed to examine the associations between Minnesota Multiphasic Personality Inventory-3 (MMPI-3) scales and the dimensional personality traits contained within the ICD-11 Personality Disorder diagnosis and DSM -5 Alternative Model for Personality Disorders (AMPD) models. The sample consisted of 489 undergraduate students, with dimensional personality traits operationalized via the Comprehensive Assessment of Traits relevant to Personality Disorder (CAT-PD). A priori hypotheses were generated for which MMPI-3 scales would be most associated with each personality trait domain, as well as individual CAT-PD scales. Zero-order correlations and regression analyses were used to examine associations between a set of hypothesized MMPI-3 scale scores and CAT-PD scale scores. The results showed a pattern of meaningful correlations supporting the majority of hypotheses. Moreover, most hypothesized scales also incremented one another in regression models predicting hypothesized PD scale scores. These findings indicate that the MMPI-3 is well situated to aid clinicians in the assessment of personality trait dysfunction from a dimensional perspective.
