A four-subtest short form of the WAIS-R that was purported to require less than 20 minutes of administration time was validated with a sample of 31 hospitalized clinically depressed patients. The four subtests of the short form (not the complete WAIS-R) were administered to the adult sample to determine the administration and scoring time of the abbreviated battery. The Kaufman Adolescent and Adult Intelligence Test (KAIT) also was administered, in counterbalanced order, to provide an external criterion of the short form's concurrent validity. The short form was quick to administer and score, and its estimate of WAIS-R Full Scale IQ correlated significantly (p < .001) with KAIT Crystallized, Fluid, and Composite IQs.
