Head injury and the Satz-Mogel type short form WAIS-R.

The current study investigated the efficacy of a Satz-Mogel type short form of the WAIS-R in a closed head injury (CHI) population and whether the short form's effectiveness varied by lesion site. Data were taken from the files of 79 CHI patients, 20 with left hemisphere damage, 15 with right hemisphere damage, 29 with bilateral damage, and 15 with only diffuse damage. Information about IQ scores and age-corrected subtest scores was examined. As expected, correlations between two forms, for both IQ scores and subtest scores were high. However, there was a remarkable percentage of deviation in scaled score points and changes in intellectual classification for some of these scores. No evidence was found to support the notion that usefulness of the short form varied according to the location of lesion.
