Cross-validation of predicted Wechsler Memory Scale—Revised scores.

Abstract

Equations for prorating the Wechsler Memory Scale-Revised General Memory (GM) and Delayed Recall (DR) index scores (J. L. Woodard & B. N. Axelrod, 1995) were confirmed in a new clinical sample of 258 patients. Raw score results for Logical Memory, Visual Reproduction, and Verbal Paired Associates were entered into the prediction equations. Predicted GM and DR scores fell within 6 points of obtained scores for 94% and 97% of the sample, respectively. A multiple regression analysis yielded multiple R 2 of.976 and.984 for GM and DR, respectively. In addition, the unstandardized regression weights were virtually identical to those initially presented by Woodard and Axelrod. These prediction equations for the GM and DR summary scores have validity for patient samples similar to those of the present study.
