Subtest administration times and short forms of the Wechsler Adult Intelligence Scale-Revised

Previous studies of short forms of the Wechsler Adult Intelligence Scale-Revised have used number of subtests as the measure of form length. The present research investigated the implications of redefining length as the time required for administration. Subtest times were recorded by two examiners in separate samples of 30 patients. Times were found to vary substantially among subtests and to be related to IQ scores in several instances. Because of these variations in administration times, the efficiency of a subtest combination is not determined solely by subtest validities.
