Assessing ICD-11 personality trait domain qualifiers with the MMPI-2-RF

Objective: The current study examined the utility of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) in assessing ICD-11 personality psychopathology trait domain qualifiers. Method: Using a community sample (N = 217) weighted for externalizing dysfunction, this study evaluated the convergence between ICD-11 trait domains as measured by the personality inventory for DSM-5 (PID-5) with hypothesized MMPI-2-RF scales. Particular emphasis was placed on evaluating the convergence between the ICD-11 trait domain qualifiers and the MMPI-2-RF personality psychopathology-5 (PSY-5) scales, as the latter are meant to represent broadband domains of personality pathology. Results: Correlation and regression analyses demonstrated expected associations between ICD-11 domains and conceptually expected MMPI-2-RF scales, with some minor exceptions. Notably, the Anankastia domain showed associations with scales assessing negative affect, but did not show expected negative associations with scales related to disinhibition. Conclusions: The findings generally supported the use of the MMPI-2-RF in assessing individual expressions of personality dysfunction from the ICD-11 trait domain qualifier perspective.
