The Rey 15-item recognition trial: a technique to enhance sensitivity of the Rey 15-item memorization test.

Numerous publications on the Rey 15-item Memorization Test have cited limitations primarily in test sensitivity, as well as to some extent in specificity. In the current study, 49 patients with suspect effort, 36 neuropsychology clinic patients not in litigation or attempting to secure disability, 33 learning disabled college students, and 60 normal controls were administered the Rey Test in standard format followed by a recognition trial. A free recall score <9 was found to have excellent specificity (97-100%), although sensitivity was modest (47%). However, use of a combined recall and recognition score (i.e., free recall + [recognition - false positives] <20) substantially increased sensitivity (71%) while maintaining high specificity (> or=92%).
