The relative performance of two Wechsler Adult Intelligence Scale‐Revised (WAIS‐R) short forms, the Satz‐Mogel item reduction technique (Adams, Smigielski, & Jenkins, 1984; Satz & Mogel, 1962) and the Silverstein (1982) subtest‐reduction technique, was examined for a group of psychiatric inpatients ( N = 75). The two short forms were evaluated on several criteria, including their ability to predict the Full Scale IQ (FSIQ) using regression analysis, their reliability, and their total administration time. The standard error of estimates obtained in predicting the FSIQ were comparable for both short forms and resulted in a ± 7 confidence interval to achieve 90% accuracy.
