Performed confirmatory factor analyses of Kaufman Assessment Battery for Children (K-ABC) using subtest correlations for standardization samples provided in manuals to test hypothesis that factors underlying K-ABC are substantially intercorrelated at all age levels for two- and three-factor models. Findings suggest K-ABC cannot distinguish between…

Cross-validated the factor analysis of the McCarthy Scales and determined construct validity for children who score one standard deviation below the normative mean on general cognitive ability. Findings discourage interpretation of the Quantitative Scale for school-age children with General Cognitive Indexes below 84. (Author)

Compared the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) score profiles of different cultural groups, using 442 White and 435 non-White subjects drawn from the kindergarten through grade 12 subset of WJTCA standardization data. Determined that data allowed for classification of the subtests by both curve and cultural effects criteria.…

Investigated the factor structure of a battery of tasks hypothesized to measure the constructs of the planning, attention, and simultaneous-successive (PASS) process model of human cognition. Results suggest that the original PASS model provides an improper factor solution. Recommends further refinement of the PASS theory or tests. (RJM)
