Abstract

This study utilized multiple criterion group neuropsychological samples to evaluate the “over-reporting” and “under-reporting” MMPI-2-RF validity scales. The five criterion groups included in this study were (1) litigating traumatic brain injury patients who failed Slick et al. criteria for probable malingering, (2) litigating traumatic brain injury patients who passed Slick et al. criteria, (3) mixed neuropsychological outpatients who passed SVTs and were diagnosed with primary neurological conditions, (4) mixed neuropsychological outpatients who passed SVTs and were diagnosed with primary psychiatric conditions, and (5) epileptic seizure disorder inpatients who were diagnosed via video-EEG. Using the data from these groups, cumulative percentages for all possible T-scores and sensitivity and specificity rates for optimal cutoff scores were determined. When specificity rates were set at 90% across all non-malingering neurological condition groups, sensitivity rates ranged from 48% (FBS-r) to 10% (K-r).
