Psychometric Properties of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) FBS-r, Fs, and RBS Scales in a Neuropsychological Setting

The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is the most widely used self-report measure of personality and psychopathology in the United States. The recently released MMPI-2-RF (Restructured Form), meanwhile, was designed to be a shorter and more efficient version of the MMPI-2. All MMPI-2-RF items are fully contained within the larger MMPI-2 and all IVIMPI-2-RE scales may be scored from a standard MMPI-2 administration. This study sought to examine the relationship between the RBS, Fs, and FBS-r over-reporting validity scales of the MMPI-2-RF, a stand-alone measure of symptom validity/cognitive effort, and neuropsychological indicators commonly used in assessment batteries. Results of this study supported the clinical utility of the RBS, FBS-r, and Fs, though RBS demonstrated superior predictive utility by explaining performance above and beyond FBS-r and Fs. Since the assessment of symptom exaggeration should be a multifactorial approach, incorporating these embedded measures of validity may provide additional information for neuropsychological assessments
