Factor analysis of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) in a brain-damaged sample.
The Wechsler Adult Intelligence Scale-Revised (WAIS-R) was factor analyzed for a sample of 100 diagnostically heterogeneous brain-damaged patients. Subjects were from two VA Medical Centers located in the Midwest with means for age, education, and Full Scale IQ of 52.31 (SD = 14.41), 11.37 (SD = 2.57), and 86.72 (SD = 10.78), respectively. A principal factor analysis followed by Varimax rotation provided evidence for the existence of three factors underlying the WAIS-R (i.e., Performance, Verbal, and Freedom from Distractibility). The present results are consistent with earlier studies that employed the 1939 and 1955 versions of Wechsler's Adult Intelligence Scale with neurologically impaired subjects.
