Sensitivity and specificity of MMPI-2 neurologic correction factors: receiver operating characteristic analysis.
A number of Minnesota Multiphasic Personality Inventory-2 (MMPI-2) items have been hypothesized to reflect neurologic symptomatology, rather than psychopathology, among closed-head-injury (CHI) patients. Some investigators have proposed a correction factor interpretive approach, which involves the deletion of such items from the MMPI-2 profile, as a method of reducing the probability of artificial clinical scale elevations due to the symptoms of CHI. The present study employed receiver operating characteristic (ROC) analysis to evaluate the sensitivity and specificity of three correction factors. All three factors demonstrated strong sensitivity when discriminating CHI patients from normal individuals but demonstrated poor specificity when discriminating CHI patients from psychiatric patients. These findings suggest that caution should be applied in using MMPI-2 neurologic correction factors, particularly with patients who might have comorbid psychiatric conditions.
