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

Abstract

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. 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. 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. 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.
