MMPI-2-RF predictors of interpersonal relationship characteristics in committed couples

There has been no systematic examination of whether scale scores on the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2011; Tellegen & Ben-Porath, 2011) are related to self- or partner-rated characteristics of romantic relationships. As such, the current study examined relations between select MMPI-2-RF scale scores and markers of relationship quality. Participants included 739 committed couples who completed the MMPI-2 and the Dyadic Adjustment Scale (Spanier, 1976; Spanier & Filsinger, 1983). Correlational analyses identified clinically meaningful negative associations between self-rated relationship satisfaction and scores on Emotional/Internalizing Dysfunction (EID) and Demoralization (RCd) for both men and women. For men and women self- and partner-rated relationship satisfaction and consensus were both meaningfully and negatively related to scores on Antisocial Behavior (RC4) and Family Problems (FML). These results are the first to provide support for the convergent validity of FML as a measure of difficulties experienced in romantic relationships. Results for EID, RCd, and RC4 converge with previous research examining relations between personality and intimate relationship qualities. Overall, these results suggest scores from the MMPI-2-RF are useful in screening for problems experienced by the individual or their partner in the context of their committed relationship.
