Résumé

This study evaluates the ability of several Wisconsin Card Sorting Test (WCST; Psychological Assessment Resources, 1990) variables to detect malingering in mild traumatic brain injury (TBI). The sample consisted of 373 TBI patients and 766 general clinical patients. Classification accuracy for seven indicators is reported across a range of injury severity and scores levels. Overall, most WCST scores were ineffective in discriminating malingering from non-malingering mild TBI patients. Failure-to-Maintain-Set, the Suhr & Boyer formula, and the King et al. formula detected about 30% of malingerers at cutoffs associated with a false positive error rate of < or =11%. The clinical interpretation and use of these indicators are discussed.
