The Symptom Validity Scale (Minnesota Multiphasic Personality Inventory-2-FBS [MMPI-2-FBS]) is a standard MMPI-2 validity scale measuring overstatement of somatic distress and subjective disability. Some critics assert the MMPI-2-FBS misclassifies too many medically impaired persons as malingering symptoms. 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. The variables included standard MMPI-2 validity scales (Lie Scale [L], Infrequency Scale [F], K-Correction [K]; FBS), objective medical data (e.g., body mass index, pulse oximetry), and polysomnographic scores (e.g., apnea/hypopnea index). The results showed the FBS had no substantial or unique association with medical/sleep variables, produced false positive rates <20% (median = 9, range = 4-11), and male inpatients showed marginally higher failure rates than females. 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). Medical impairment does not appear to be a major influence on deviant MMPI-2-FBS scores. |
