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

Test-retest reliability of the WAIS-R Satz-Mogel short form in a normal elderly sample

Test-retest reliability of the WAIS-R Satz-Mogel short form was tested on a sample of 122 normal elderly volunteer subjects with mean age of 70.4. Subjects' performance was assessed over 3 annual probes. Reliability coefficients for sums of scaled scores on Verbal subscale and Full Scale ranged between 0.79 and 0.83. Corresponding coefficients for Performance subscale ranged between 0.70 and 0.72. The percentage of subjects who showed change between two probes of more than 1 SD was the highest for the Performance subscale. Implications for clinical use, particularly for the purpose of estimation of premorbid intellectual functioning are discussed.

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.
