| Abstract: | The present study used a known-groups design to determine the classification accuracy of 10 MMPI-2 validity scales and indicators in the detection of cognitive malingering in traumatic brain injury. Participants were 259 traumatic brain injury and 133 general clinical patients seen for neuropsychological evaluation. The TBI patients were subdivided into groups based on a comprehensive examination of effort following Slick, Sherman, and Iverson's (1999 Slick , D. J. , Sherman , E. M. S. , & Iverson , G. L. ( 1999 ). Diagnostic criteria for malingering neurocognitive dysfunction: Proposed standards for clinical practice and research . The Clinical Neuropsychologist , 13 , 545 – 561 . [INFOTRIEVE] [CSA] [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) criteria. More extreme scores demonstrated excellent specificity; often impressive sensitivity was seen even while maintaining a low false positive error rate. Specificity was good even in stroke, memory disorder, and psychiatric patients without incentive. The results of this study are presented in frequency tables that can be easily referenced in clinical practice. |
