Considerable debate exists regarding the accuracy of intelligence tests with members of different groups. This study investigated differential predictive validity of the "Wechsler Intelligence Scale for Children-Fourth Edition". Participants from the WISC-IV--WIAT-II standardization linking sample (N = 550) ranged in age from 6 through…

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)

The scores of elementary school students on the Quick Test were compared with scores on the Full Scale Wechsler Intelligence Scale for Children-Revised. The relationship between the two tests varied significantly with age and intelligence levels. (Author/CP)

High intercorrelations among the six subtests of the Pictorial Test of Intelligence raise questions regarding the construct validity of the instrument. A factor analysis was performed. A single factor with stable factor loadings emerged. (Author/JKS)

Forty elementary students were administered the Bender-Gestalt Test using two techniques: Koppitz routine instructions and the Hutt testing-the-limits method. The mean number of Koppitz errors was approximately two greater than the number obtained using the Hutt technique. (Author/BW)

Measures of multivariate reliability were calculated for profiles of Wechsler Intelligence Scale for Children (WISC) subscales on three age groups. Profile dimensions based on reliability considerations were established and matched across age groups and with factor analytic dimensions. WISC was found to measure general ability and verbal and…

The Wechsler Intelligence Scale for Children-Revised, the Slosson Intelligence Test, and the National Education Development Test were administered to a small sample of private school children ranging in age from 12.3 to 14.1 years. Correlations among these measures were moderate to high. (JKS)

The concurrent validity and reliability of abbreviated versions of the WISC-R were estimated for a group of one hundred children between six and sixteen years of age. These abridged scales offered satisfactory estimates of reliability and validity. (Author/JKS)

The Wechsler Intelligence Scale for Children-Revised Full Scale IQ did not yield valid predictions of achievement of educable mentally handicapped students in a public school setting, as measured by the Wide Range Achievement Test (WRAT). (Author/CM)

The Ozawa Behavioral Rating Scale contains six items related to distractibility and nine items related to impulsivity. This validity study showed that the Scale shows statistically significant relationships with the Wechsler Intelligence Scale for Children--Revised and the Matching Familiar Figures Test and may be appropriate for identifying…

The usefulness of the Peabody Individual Achievement Test General Information subtest as a general screening instrument with non-retarded subjects is shown in a study of concurrent validity between the subtest and the Wechsler Intelligence Scale for Children-Revised. Correlations between the instruments in two intelligence groups are discussed.…

Applied factor analysis to the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) scores for 505 gifted students, to evaluate the construct validity of the WISC-III with this population. Results are consistent with the hypothesis that subtests that emphasize speed of reading are not valid for gifted children and suggest that an…

Six methods of measuring factorial similarity were compared with regard to outcome based on two large data sets, one for an intelligence test and the other for a personality test. All indexes yielded comparable results. Comparing factors determined at random, all indexes yielded comparable results leading to a conclusion of dissimilarity.…

The Wechsler Intelligence Scale for Children, and the revised form of that measure, were administered to a sample of sixth grade pupils. Although the correlation between measures was high, scores on the revised form were significantly lower. (JKS)

A procedure is proposed for determining whether correlations obtained between two measures justify the assumption that the measures are identical. It is intended especially for small samples. In the example, the performance scales of two intelligence tests were administered to 32 deaf adolescents. (GDC)
