Effects of lesion laterality on the Satz-Mogel WAIS-R short form.

Effects of lateralized brain damage on the Satz-Mogel (1962) WAIS-R short form were examined. Patients (N = 65) were assigned to groups based on diffuse, predominantly left, or predominantly right brain damage. Overall, results supported the validity of the Satz-Mogel short-form IQs with neurological patients, although there were significant ANOVA results for various subtests when original scores were compared to short-form scores. A comparison of groups in regard to the number of deviations (i.e., +/- 3) from original WAIS-R subtests raised questions with regard to the effects of lesion laterality on certain short-form subtest scores. Criteria for evaluating short forms and issues for further research are discussed.
