Data collection can be the most time- and cost-intensive part of developmental research. This article describes some long-proposed but little-used research designs that have the potential to maximize data quality (reliability and validity) while minimizing research cost. In "planned missing data designs", missing data are used…

Analyzes whether the latest version of the Wechsler Intelligence Scale for Children (WISC-III) measures the same constructs across its 11 age spans and what constructs are measured by the WISC-III. Findings indicate that WISC-III does measure the same constructs across ages but does not measure Freedom from Distractibility. (RJM)

Examined the predictive validity of the Wechsler Intelligence Scale for Children (Revised) in 64 Mexican-American children. All the correlations among the WISC-R factor scores and academic achievement were low. In contrast, significant relationships were observed between IQ scores and achievement measures, suggesting utility of the WISC-R IQs in…

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…

Thirty elementary students referred for possible learning disability were administered the achievement sections of the Woodcock-Johnson Psycho-Educational Battery and several traditionally used school district tests. Identical student placement decisions were reached on 23 out of 30 students. (Author/GDC)

Tests of the validity of the Wechsler Intelligence Scale for Children Third Edition Arithmetic, Coding, Information, and Digit Span (ACID) profile among 612 students with learning disabilities revealed that the ACID profile does not efficiently separate children with disabilities from those without disabilities. No ACID cutting score significantly…

This study evaluated the construct validity of the Wechsler Intelligence Scale for Children, Third Edition (WISC-III) with children (ages 8 to 13) having learning disabilities who were either Hispanic (N=120) or Non-Hispanic white (N=120). Factor analyses found that the WISC III has a three factor structure consisting of verbal comprehension,…

The Wechsler Intelligence Scale for Children-Revised (WISC-R) Comprehension, Arithmetic, and Object Assembly and McCarthy Quantitative and Memory Indices were most sensitive to learning disabled students' achievement. Conversely, the WISC-R Similarities and Arithmetic and the McCarthy Verbal Index were most sensitive to achievement of nonlearning…

The performance of 79 elementary school students referred for learning disability evaluation was compared on the Kaufman Assessment Battery for Children (K-ABC), the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Woodcock-Johnson Psychoeducational Battery (WJPEB). Pearson product-moment correlations were performed on the global…

Results of an assessment of the diagnostic validity of the Luria-Nebraska Neuropsychological Battery-Children's Revision (LNNB-C) with the Wechsler Intelligence Scale for Children-Revised (WISC-R) for the following relevant diagnostic groups: neurological, psychiatric, and normal controls are reported. (Author/BL)

Elementary school children (N=41) were administered Kaufman Assessment Battery for Children (K-ABC), Wechsler Intelligence Scale for Children-Revised (WISC-R), and Stanford-Binet. Analyses appeared to support the viability of the K-ABC as measure of the properties of mental functioning that are similar to those measured by WISC-R and…

Reports findings about the relationship between the Kaufman Assessment Battery for Children (K-ABC), the Weschler Intelligence Scale for Children-Revised (WISC-R), and the Stanford-Binet for 40 children with no known impairments. The overall results suggested some support for the use of the K-ABC as a measure of intelligence. (BH)

Compared the Cognitive Levels Test (CLT) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) scores for 55 children who were referred for remedial educational services. A comparison of the correlations for each of the criterion measures from the WISC-R showed a consistent significant positive relationship with the CLT. (Author/LLL)

Construct validity of the Wechsler Intelligence Scale for Children-Revised using 189 Black, 184 Hispanic, and 187 White 6- to 11-year-olds was investigated. A two-factor solution yielded similar loadings corresponding to verbal comprehension and perceptual organization for all three groups. Three-factor solutions yielded similar loadings for…

This study examined the concurrent validity and diagnostic efficiency of the Kaufman Brief Intelligence Test (K-BIT) with 75 elementary and middle school students with learning disabilities, who had been referred for triennial multidisciplinary re-evaluations. High and significant correlations were found between the K-BIT and the Wechsler…
