Journal ArticleDOI
A comparison of WMT, CARB, and TOMM failure rates in non-head injury disability claimants
TL;DR: Tests of recognition memory using digits, pictorial stimuli or verbal stimuli, all of which are objectively extremely easy tasks, resulted in widely different failure rates, suggesting that, while these tests may be highly specific, they vary substantially in their sensitivity to response bias.
Journal ArticleDOI
Development and Validation of a Response Bias Scale (RBS) for the MMPI-2
TL;DR: Study results suggest that the Response Bias Scale may be a useful addition to existing MMPI-2 validity scales and indices in detecting symptom complaints predominantly associated with cognitive response bias and overreporting in forensic neuropsychological and disability assessment settings.
Journal Article

Roger O. Gervais,Anthony S. Russell,Paul Green,Lyle M. Allen,Robert Ferrari,Stephanie Pieschl +5 more
TL;DR: This study illustrates the importance of assessing for exaggeration of cognitive symptoms and biased responding in patients with FM presenting for disability related evaluations.
Journal ArticleDOI
Incremental Validity of the MMPI-2-RF Over-reporting Scales and RBS in Assessing the Veracity of Memory Complaints
TL;DR: The incremental validity of MMPI-2-RF over-reporting validity scales and RBS in assessing memory complaints is examined, consistent with the development objectives of the M MPI- 2-RF validity scales as more efficient and sensitive measures of symptom over- reporting.
Journal ArticleDOI
Further validation of the MMPI-2 and MMPI-2-RF Response Bias Scale: findings from disability and criminal forensic settings

TL;DR: The results of this study indicate that the RBS can add uniquely to the existing MMPi-2 and MMPI-2-RF validity scales in detecting symptom exaggeration associated with cognitive response bias.
