The accuracy of the WAIS-R seven subtest short form (Ward, L.C., 1990. Prediction of Verbal, Performance and Full Scale IQs from seven subtests of the WAIS-R. J. Clin. Psychol. 46, 436-440) was examined for predicting IQs of 73 inpatients diagnosed with schizophrenia. Results indicated that 93% of the estimated Full Scale IQs were within ±5 points of their actual scores. Using Wechsler's (1981) seven category intelligence classification, the level of agreement on the Full Scale IQ was 84% for the standard WAIS-R and the seven subtest short form. This abbreviated Wechsler Scale may be used with schizophrenic patients when only general estimates of intellectual functioning are required. (C) 1999 Elsevier Science B.V. All rights reserved.
