Rey II: redesigning the Rey screening test of malingering

This study has redesigned the Rey 15-item Visual Memory Test (1964) by introducing more complex figures and by increasing internal logic and pattern redundancy. Standardized administrative procedures and rules for a simple qualitative scoring system were established. Performance on the original Rey continued to be significantly contaminated by ability components and illness while performance on the Rey II qualitative scoring system was not significantly related to intelligence, age, mental status or memory. The Rey II demonstrated improved face validity. Linear Discriminant Function Analysis indicated that the qualitative scoring system had a higher classification accuracy than the quantitative system on both instruments; the Rey II qualitative scoring system accurately detected 31% more college malingerers than the Rey quantitative and 21% more clinical malingerers than the Rey II quantitative. A malingering cut-off of two qualitative errors gave the Rey II a 79% higher sensitivity in the college malingerers and 29% higher specificity in the clinical population than the standard quantitative Rey cut-off of nine items.
