Abstract
The Wechsler Memory Scale-Revised (Wechsler, 1987) was elaborated by a dding 20 recognition items for Logical Memory (LM) and by adding recog nition, matching, and copy trials for Visual Reproductions (VR). Relia bility was very good for VR copy (alpha=.77, interrater agreement, 100 % within 1 point). Reliability was modest for LM recognition (alpha=.4 2) and for VR recognition (alpha=.58), but reasonable given the small number of items on each measure. The reliability coefficient was very weak for VR matching (alpha=.10), limited considerably by the ease of the task for this healthy sample and by the small number of items. Aft er statistically correcting for imperfect reliability, validity coeffi cients (correlations with similar tests that are well standardized) we re good for all of the new trials (r=.60 to r=1.00). Age- and educatio n-appropriate reference data are provided using 81 healthy adults. Fur ther validation using theoretically and clinically meaningful patient groups would be very valuable. In the meantime, the new trials should serve the clinician well as screening tools.
