Medical impairment does not appear to be a major influence on deviant MMPI-2-FBS scores.

The MMPI-2-FBS appears to have acceptable specificity, because it did not misclassify as biased responders those medical patients with sleep problems, male or female, with primary gain only (reducing sickness). The results showed the FBS had no substantial or unique association with medical/sleep variables, produced false positive rates less than 20% (median = 9, range = 4-11), and male inpatients showed marginally higher failure rates than females. 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.

The variables included standard MMPI-2 validity scales (Lie Scale, Infrequency Scale, K-Correction FBS), objective medical data (e.g., body mass index, pulse oximetry), and polysomnographic scores (e.g., apnea/hypopnea index). 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 tests the assertion of malingering misclassification with a large sample of 345 medical inpatients undergoing sleep studies that standardly included MMPI-2 testing. Some critics assert the MMPI-2-FBS misclassifies too many medically impaired persons as malingering symptoms. Since the assessment of symptom exaggeration should be a multifactorial approach, incorporating these embedded measures of validity may provide additional information for neuropsychological assessments.The Symptom Validity Scale (Minnesota Multiphasic Personality Inventory-2-FBS ) is a standard MMPI-2 validity scale measuring overstatement of somatic distress and subjective disability. 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. 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. 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. The recently released MMPI-2-RF (Restructured Form), meanwhile, was designed to be a shorter and more efficient version of the MMPI-2.

The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is the most widely used self-report measure of personality and psychopathology in the United States.
