HIERARCHICAL FACTOR STRUCTURE OF THE WECHSLER INTELLIGENCE SCALE FOR CHILDREN .3.

R. J. Wherry and R. J. Wherry (1969) hierarchical factor solutions wer e obtained on the Wechsler Intelligence Scale for Children-III interco rrelations reported in the standardization sample (D. Wechsler, 1991). Two- and 4-factor solutions were obtained for the 6-7, 8-10, 11-13, a nd 14-16 age levels. Both solutions indicated a strong general intelli gence (g) factor at all 4 age levels. At the primary level, factors co rresponding to the verbal-numerical-educational and spatial-mechanical -practical dimensions from Vernon's (1950) paradigm emerged when a 2-f actor solution was used. When a 4-factor solution was used, Perceptual Organization, Perceptual Speed, Verbal Comprehension, and Freedom Fro m Distractibility factors were obtained at the primary level.
