Abbreviated WAIS-R procedures: Use and limitations with head-injured patients

Abstract
The utility of the Satz-Mogel and Silverstein (two and four subtest) short forms of the WAIS-R was assessed on a group of 49 recently head-injured patients. The Satz-Mogel procedure yielded correct categorical classification of IQ in 92% of the cases and correlated highly with WAIS-R FSIQ (r = .97). Silverstein two-and four-subtest forms correlated highly with WAIS-R FSIQ (r = .82; r = .86) but resulted in a larger number of IQ classification errors. These data support the superiority of the Satz-Mogel procedure for abbreviating the WAIS-R with head-injured patients. Applications and limitations of short forms in the assessment of intelligence with head-injured patients are discussed.
