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

Area of Science:

• Psychological assessment
• Relationship psychology
• Clinical psychology

Background:

• The Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) is a widely used psychological assessment tool.
• Previous research has not systematically explored the relationship between MMPI-2-RF scores and romantic relationship quality.
• Understanding these associations can inform clinical practice and relationship counseling.

Purpose of the Study:

• To examine the relationship between specific MMPI-2-RF scale scores and self- or partner-rated relationship quality.
• To investigate the convergent validity of MMPI-2-RF scales in the context of romantic relationships.

Main Methods:

• A sample of 739 committed couples completed the MMPI-2 and the Dyadic Adjustment Scale.
• Correlational analyses were used to assess the associations between MMPI-2-RF scale scores and relationship quality markers.

Main Results:

• Negative associations were found between self-rated relationship satisfaction and scores on Emotional/Internalizing Dysfunction (EID) and Demoralization (RCd) for both men and women.
• Self- and partner-rated relationship satisfaction and consensus were negatively related to scores on Antisocial Behavior (RC4) and Family Problems (FML) in both men and women.
• The Family Problems (FML) scale demonstrated convergent validity as a measure of relationship difficulties.

Conclusions:

• MMPI-2-RF scores are associated with relationship quality, suggesting their utility in identifying individuals or partners experiencing relationship difficulties.
• Findings support the convergent validity of the FML scale and align with previous research on personality and intimate relationships.
• The MMPI-2-RF can be a valuable tool for screening and understanding challenges within committed relationships.
