Since the original Wechsler Intelligence Scale for Children (WISC, 1949) had recently undergone a major revision in content structure of the test and in the populations utilized for standardization, the present study sought to examine the factor structure of the Wechsler Intelligence Scale for Children-Revised (WISC-R, 1974) using test data from 126 white and black fifth graders from a predominantly lower middle class socioeconomic background. The analysis of data was performed by a principal components method of factor analysis utilizing Varimax rotation. The results of the data analysis indicated the presence of three primary group factors, and these factors closely resembled those found by researchers using the WISC. The first factor accounted for 42.3% of the total variance and was heavily loaded with Verbal subtests of the WISC-R, e.g. Information, Vocabulary, and Similarities. The second factor accounted for 10.7% of the total variance and was heavily loaded with Performance subtests of the WISC-R, e.g. Block Design, Object Assembly, and Picture Completion. The third factor accounted for 9.3% of the total variance and was heavily loaded with two Verbal subtests (Arithmetic and Digit Span) and one Performance subtest (Coding).
