The present study examined the predictive accuracy of the test by examining the performance of three groups of participants: (a) 92 noncredible patients (as determined by failed psychometric and behavioral criteria and external motive to feign), (b) 51 general clinical patients with no motive to feign, and (c) 31 learning disabled college students. Results demonstrated gender differences in performance that necessitated separate cutoff scores for men and women. Use of a cutoff score of < or = 7 words correctly recognized identified 80.5% of noncredible female patients while maintaining specificity of > 90%. However, to achieve this level of specificity in male noncredible patients, the cutoff score had to be lowered to < or = 5, with resultant sensitivity of only 62.7%. A combination variable (recognition correct minus false positive errors + number of words recognized from the first 8 words) showed enhanced sensitivity in identifying suspect effort in a subset of the noncredible sample who were claiming cognitive symptoms secondary to traumatic brain injury (i.e., cutoff score of < or = 9 = 81.6% sensitivity with 90% specificity). Results indicate that the Rey Word Recognition Test is an accurate and cost-effective method for the detection of noncredible cognitive performance.
