A procedure for the rapid computation of WISC-R factor scores

Presents a table that provides a simplified procedure for obtaining WISC-R factor scores expressed as IQ equivalents. Three factors, based on Kaufman's recent analysis of the 1974 Revised WISC, were included: (1) Verbal Comprehension (Information, Similarities, Vocabulary, and Comprehension); (2) Perceptual Analytic (Picture Completion, Picture Arrangement, Block Design, Object Assembly, and the optional subtest, Mazes); and (3) Attention Concentration (Arithmetic, Digit Span, and Coding). The techniques for deriving the factor score equivalents and the use of the table, both procedurally and clinically, are discussed.
