CROSS-VALIDATION OF PREDICTED WECHSLER MEMORY SCALE - REVISED SCORES

Equations for prorating the Wechsler Memory Scale-Revised General Memo ry (GM) and Delayed Recall (DR) index scores (J. L. Woodard & B. N. Ax elrod, 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. Predicte d GM and DR scores fell within 6 points of obtained scores for 94% and 97% of the sample, respectively. A multiple regression analysis yield ed multiple R(2) of .976 and .984 for GM and DR, respectively. In addi tion, the unstandardized regression weights were virtually identical t o those initially presented by Woodard and Axelrod. These prediction e quations for the GM and DR summary scores have validity for patient sa mples similar to those of the present study.
