Joint Factor Analysis of the Woodcock-Johnson Psychoeducational Battery-Revised and the Detroit Tests of Learning Aptitude-Adult.
McGhee, Ron; And Others
The organization of cognitive factors in a sample of older adults was investigated by a joint factor analysis of the subtests from the Woodcock-Johnson Psychoeducational Battery-Revised (WJ-R) and the Detroit Tests of Learning Aptitude-Adult (DTLA-A). Two extensive batteries were administered, following R. W. Woodcock's recommendation that in order for factors to be identified, a sufficient number of markers for each factor must be present. Subjects for the study were 41 adults ranging in age from 55 to 76 years. Altogether, 9 sets of exploratory and confirmatory factor analyses on 29 variables were conducted. The results provide evidence for nine latent factors based on the theory of fluid and crystallized intelligence (Gf-Gc) theory of intelligence of J. L. Horn and R. B. Cattell (1966). Theoretical and practical implications of the findings are discussed. (Contains 8 tables and 21 references.) (Author/SLD)
