Analyzed the intercorrelations among the 11 subtests of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) in the nine age groups in the normative sample. Results suggested that the factor structure underlying the WAIS-R is complex and that a large proportion of WAIS-R performance can be explained by a general intellectual factor. (LLL)

A study concluding that the Wechsler Adult Intelligence Scale (Revised) (WAIS-R) has three clear factors in its structure is critiqued. An alternative factor comparison technique, FACTOREP, is used with identical data. It is demonstrated that the WAIS-R has only two strong factors--verbal comprehension and perceptual organization.
