A comparison of the Wechsler-Bellevue and Shipley-Hartford Scales as measures of mental impairment.

Abstract

100 hospitalized patients of a wide age range who met all conditions for valid test records were given both tests. Wechsler-Bellevue Indices of impairment, corrected for age, correlated 13 with Shipley-Hartford Conceptual Quotients. With older patients the Shipley-Hartford revealed a decided drop in score, whereas the opposite was true with the corrected Wechsler-Bellevue Index. "One must conclude that these two measures of mental impairment bear little relationship to each other, and apparently are not measuring the same aspects of mental functioning."
