The Minnesota Multiphasic Personality Inventory-2-Restructured Form in the epilepsy monitoring unit.
The Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) is a restructuring of the MMPI-2 that has improved the psychometric characteristics of the test. The primary aim of this study was to provide diagnostic utility data on the MMPI-2-RF in an epilepsy monitoring unit population (N=429). Mean comparisons revealed group differences on Validity Scales Fs and FBS-r; Restructured Clinical Scales RC1 and RC3; and Somatic Scales MLS, GIC, HPC, and NUC. Diagnostic utility data are provided for those scales with the largest effect sizes: RC1, FBS-r, and NUC. On RC1, sensitivity was 76% and specificity was 60%, similar to values found when applying published decision rules to the MMPI-2. RC1 explains unique variance in diagnosis beyond that explained by demographic or medical history risk factors. We provide likelihood ratios for scores on RC1, FBS-r, and NUC that can be used by the clinician to calculate posttest odds and probability of nonepileptic seizures using the base rate of nonepileptic seizures in his/her population.
