Objective: Validation studies of the Minnesota Multiphasic Personality Inventory –Second Edition Restructured Form (MMPI-2-RF) have not examined classification accuracy of exaggerated emotional disturbance defined by the Malingered Mood Disorder Scale (MMDS). MMDS research suggests utility identifying personal injury litigants and disability claimants who exaggerate emotional disturbance. The current study examined the classification accuracy of an abbreviated MMDS scale compared to the original MMPI-2 counterpart. Method: Archival data from 115 outpatients referred for neuropsychological evaluation was examined, and Chi-Square goodness of fit tests were conducted to examine the proportion of cases from the MMDS scale that would be invalid when compared with the abbreviated MMDS. Results: There was a significant difference between the proportion of invalid cases found by the MMDS abbreviated scale, 39.13%, when compared to 56.52% found by the original scale, χ2 (1, n = 115) = 14.12, p ≤ .001). Kappa Measurement of Agreement between the MMDS scale and the abbreviated form ranged from moderate to good. Sensitivity of the abbreviated MMDS was 69.2%; specificity was 100%. Conclusion: Findings suggest the abbreviated form of the MMDS significantly differed in classification profiles of invalid and valid cases, however, future research can examine the utility of an abbreviated MMDS in a known groups sample.
