WAIS—R abbreviated forms in the elderly: A comparison of the Satz-Mogel with a seven-subtest short form.

The Satz-Mogel abbreviation of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) was compared with a 7-subtest short form (Ward, 1990) in samples of normal and neurologically impaired elderly persons 75 years and older. The normals were 130 subjects from the old-age WAIS-R standardization sample, and the brain-damaged group consisted of 40 men with medically diagnosed brain dysfunction averaging 79.57 (SD = 5.4) years of age. The short forms were highly similar in administration times, correlations with the WAIS-R IQs (all rs >.92), estimation of the average IQ scores, and in classification of intelligence for both the normal and neurologically impaired subjects. Finally, both short forms correctly estimated significant Verbal IQ-Performance IQ discrepancies about 75% of the time
