Concurrent validity of three WAIS—R short forms in psychiatric inpatients.

Several investigators have proposed short forms of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) to provide more cost-effective estimates of intellectual ability. The present study compared the concurrent validity of Silverstein's (1982) 2-subtest, Doppelt's (1956) 4-subtest, and Ward's (1990) 7-subtest short forms in predicting the WAIS-R Full Scale IQs of 304 psychiatric inpatients
