Use of the Satz-Mogel abbreviated WAIS with hospitalized geriatric patients

The equivalency of standard and Satz-Mogel WAIS scales for psychiatrically hospitalized geriatric patients was studied using a matched control and experimental group, test-retest design. On the Verbal, Performance, Full Scale, and subtest scales the two forms had distributions whose central tendencies and variances were statistically equivalent. Score reliability for the two forms was shown by the finding of only one significant test-retest correlational difference between corresponding scales for the two groups and by difference-score variances which generally pointed to only a slight statistical tendency of the short form to generate larger differences between test and re-test scores.
