Assessing Physical Pain Perception and Psychological Distress Tolerance through the MMPI-2-RF: A Comparison of Multimethod Measures.

While transdiagnostic factors are important domains in clinical assessment and treatment, there is little research to link such constructs to widely accepted and utilized broadband assessments such as the Minnesota Multiphasic Personality Inventory, 2nd edition - Restructured Form (MMPI-2-RF). A handful of studies suggest the ability of the MMPI-2-RF scales to capture variance in transdiagnostic constructs; however, this literature relies solely on self-report criterion measures, despite evidence that self-report and behaviorally-indexed correlates of psychopathology may measure varied aspects of the intended construct and can often yield differing results. The current study investigated MMPI-2-RF scales' ability to assess two widely examined transdiagnostic constructs, distress tolerance and pain perception, across both self-report and behavioral indicators. The sample included 115 undergraduate students who completed a valid MMPI-2-RF and multimethod measures of pain perception and distress tolerance. The results aligned with prior research in areas of internalizing symptoms, psychopathy, and suicide risk factors in self-report, but not behaviorally-based, assessment. Implications of this inconsistency, the association between clinical assessment and transdiagnostic constructs, and the heterogeneity of the distress tolerance and pain perception constructs are discussed.
