This study evaluated a measure of feigned cognitive symptoms, the MMPI-2 Response Bias Scale (RBS), using an analog simulation design. A total of 81 participants were randomly allocated to one of two conditions: simulation (n = 40) or control (n = 41). Simulators were instructed to feign memory impairment. All participants completed an abbreviated form of the MMPI-2, Warrington%26apos;s Word Recognition Memory test, and the Test of Memory Malingering. MMPI-2 data were used to calculate the RBS, F, K. FBS scores were prorated. Significant group differences were found on all measures. The effect size of group differences was largest for the RBS (d = 2.52) compared to the prorated FBS (d = 2.11), F (d = 1.31), and K (d = 0.85). Despite strong significant correlations between MMPI-2 scores, the RBS added incrementally to the other validity indicators in the prediction of group membership. The results from this RBS simulation study are consistent with several previous known-groups evaluations, which suggest that this scale is a useful indicator of negative response bias associated with exaggerated memory impairment.
