Adapted the Peabody Picture Vocabulary Test to facilitate administration to low-functioning autistic children who do not have a pointing response. Autistic (N=10) and preschool-aged children (N=20) were given the standard form and the adapted form. Results supported the use of the published norms for the adapted version. (Author/RC)

To examine the concurrent and construct validity of the Slingerland Screening Tests (SST) for Children with Specific Language Disability in the assessment of learning disabilities, 382 children in grades 1 through 4 were given both the SST and an IQ test. The SST errors were significantly negatively correlated with IQ scores. (Author)

Investigated the validity of the Luria-Nebraska Intellectual Processes Scale (IPS) as a substitute for the Wechsler Adult Intelligence Scale (WAIS). IPS scores were correlated with the three WAIS IQs, and regression equations were computed to obtain estimated Verbal IQ, Performance IQ, and Full Scale IQ. (Author)

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)

Ninety-four college students were administered the General Ability Measure for Adults (GAMA) and Kaufman Adolescent and Adult Intelligence Test (KAIT). GAMA IQs were significantly and moderately correlated with KAIT Fluid, Crystallized and Composite IQs, supporting the convergent validity of this instrument. Although significant correlations…

Discusses clinical, efficacy, and validity issues pertaining to the use of computerized IQ testing by comparing computer-based test interpretations (CBTIs) of the Wechsler Intelligence Scale for Children--Revised with reports written by a clinical psychologist. A group of 33 expert clinicians rated the CBTIs significantly higher. (Author/LRW)

This study compared global scores of 26 Australian students (ages 4 to 16) with mental retardation on the third and fourth editions of the Stanford Binet Intelligence Scale. Analysis indicated a fairly strong positive relation between the two tests, suggesting that the fourth edition may be substituted for the older instrument in longitudinal…

Thirty-two preschool children were administered the Cognitive Levels Test (CLT) to evaluate its temporal stability and concurrent validity. Results indicated good temporal stability for the CLT-Cognitive Index and high correlations between the CLT-Cognitive Index and the Stanford-Binet: Fourth Edition. (Author/JDD)

This study examined patterns of nonverbal intelligence test performance of 11 preschool children with and 12 without specific language impairments. The study found group differences in relations among nonverbal cognitive skills. Results suggest caution in using nonverbal intelligence tests normed on nondisabled children with children having…

Fifty gifted students, aged 9-17, were tested with the gifted identification battery from Stanford-Binet IV and the SRA Educational Ability Series (EAS). The EAS was found to be a feasible test for screening gifted students. The discrepancies between the standard scores of the two tests were low and favored the EAS. (Author/JDD)

Scores of 38 learning-disabled college students on the revised Wechsler Adult Intelligence Scale (WAIS-R) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) were compared. Results indicated significant correlations between the tests, though subjects tended to obtain higher scores on the WISC-R than on the WAIS-R. (Author/DB)

Examines the concurrent validity of the General Ability Measure for Adults (GAMA) and the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III). A comparison of the sample's mean scores indicates similar GAMA and WAIS-III Performance IQ scores. In contrast, the sample's mean GAMA IQ score was significantly lower than the sample's mean Full…
