Examined similarity of scores of 30 learning disabled students (aged 16 and 17) on the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Wechsler Adult Intelligence Scale-Revised (WAIS-R). Results documented similarity between WISC-R and WAIS-R for 16 year-olds who were learning disabled and had average intellectual ability.…

The consistency by which shared abilities are assessed on three intelligence tests was investigated. Instruments under consideration include: the Wechsler Intelligence Scale for Children-Revised, the Kaufman Assessment Battery for Children, and the Stanford-Binet Intelligence Scale-Fourth Edition. A list of shared abilities and the subtests…

Compared the Wechsler Intelligence Scale for Children (Revised) (WISC-R) and the Leiter International Performance Scale with 40 average and above average students. Results indicated a curvilinear relationship between the WISC-R and the Leiter, which correlates higher at the mean and deviates as the Full Scale varies from the mean. (JAC)

Reanalysis of Wakefield and Carlson's data confirmed canonical correlations of .84 and .69, but analysis of redundancies revealed that only 34 percent of the total WISC subtest variance is redundant with the ITPA and 39 percent of the ITPA subtest variance is redundant with the WISC. (Author)

Investigated factor structures of Wechsler Intelligence Scale for Children-Revised (WISC-R) and Kaufman Assessment Battery for Children (K-ABC) for 212 normal children. Findings suggest correspondence between: (1) WISC-R Verbal Comprehension and K-ABC Achievement; (2) WISC-R Perceptual Organization and K-ABC Simultaneous Processing; and (3) WISC-R…

Compared the Wechsler Intelligence Scale for Children (Revised) and the Woodcock-Johnson Psycho-Educational Battery (W-J) for 142 children with regular and learning-disabled (LD) class placement. The W-J and WISC-R evidenced low to moderate correlations and significant mean differences. W-J/WISC-R correlations for the regular students exceeded…

Administered the Wechsler Intelligence Scale for Children, Wechsler Intelligence Scale for Children-Revised, and Wechsler Preschool Primary Scale of Intelligence in a counterbalanced design to randomly selected elementary school children (N=72). Results indicated that the verbal Intelligence Quotients (IQs) were comparable, but the performance and…

Examined concurrent validity of Stanford-Binet Intelligence Scale, 4th edition (SB IV) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) in a homogeneous, nonexceptional sample of 32 early elementary school children. Findings suggest that SB IV has significant positive relationship with WISC-R. The tests displayed a moderate level…

Evaluated the validity of the Slosson Intelligence test as determined by the Wechsler Intelligence Scale for Children-Revised (WISC-R). Results indicated that the Slosson correctly predicted functioning level to within 10 IQ points of the WISC-R Full Scale scores for 88 percent of the subjects. (LLL)

Thirty-five gifted elementary children were tested with the Wechsler Intelligence Scale for Children III (WISC-III) and results were compared to a previous administration of the WISC (Revised). Scores were significantly higher on all three WISC-R global scales and most subtest scaled scores. Correlation coefficients between the tests were…

The concurrent validity of the Kaufman Assessment Battery for Children (K-ABC) was examined by comparing K-ABC scores and Weschler Intelligence Scale for Children--Revised (WISC-R) scores for 58 school children in primary and intermediate grades. Thirty-seven of these children had either educable mental retardation, learning disabilities, or…

Investigated the external validity of the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) in learning disabled (LD) elementary school children (N=60). Results suggested that the WJTCA's achievement emphasis jeopardizes its validity for assessing and classifying LD students within the currently accepted and mandated ability-achievement…

Examined the relationship between the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) and Wechsler Intelligence Scale for Children-Revised (WISC-R) in a referral sample of 52 elementary students. Results showed comparable WJTCA/WISC-R global ability estimates, contrary to lower WJTCA scores found in recent studies with learning disabled…

Investigated the concurrent validity of the Wechsler Intelligence Scale for Children (Revised) subtests and three IQs compared to Wide Range Achievement Test standard scores, in 28 learning-disabled children. Analysis showed no significant correlations between WISC-R and WRAT scores, indicating a lack of concurrent validity on the WAIS-R. (WAS)

The Slosson Intelligence Test (revised norms) (SIT) and the WISC-R (Wechsler Intelligence Scale for Children-Revised) were compared. Results provide a moderate degree of support for the concurrent validity of the revised SIT norms, using the WISC-R as the criterion. However, the intelligence quotients on the two tests may not be interchangeable.…
