Reports the validities and reliabilities of two short forms of the Wechsler Adult Intelligence Scale (Revised) (Vocabulary and Block Design, and Arithmetic and Picture Arrangement) for each of nine age groups, together with standard errors of estimate and measurement. Results support the use of these forms for their intended purpose. (BH)

Reports reliability data for Wechsler Subtest comparisons to supplement the data in the Wechsler Intelligence Scale for Children-Revised and Wechsler Adult Intelligence Scale-Revised manuals. Results indicated that the reliabilities of the differences between Wechsler Subtest scores are low enough to warrant the exercise of caution in interpreting…

The test-retest IQs of 50 patients were correlated. The patients were included in the sample only because they had been given the Wechsler Adult Intelligence Scale before. The interval between test and retest averaged almost two years. All test-retest correlations were .90 or better. (Author)

Examined relative efficacy of two short forms of Wechsler Adult Intelligence Scale-Revised (WAIS-R) with respect to accurate subtest profile scatter (N=50). Subtest scores of both split-half Satz-Mogel short form and criterion referenced Modified WAIS-R (WAIS-RM) short form were found to differ significantly from full-length WAIS-R subtest scores.…

Administered three Wechsler adult intelligence scales to 72 undergraduates and tested the quality of means, variances, and covariances, utilizing subtest scale scores and IQs. Results indicated that the three scales were not parallel. Generally, the subtest scaled scores exhibited less similarity across the three scales than the IQ estimates.…

Performed orthogonal and oblique factor analysis using the Wechsler Adult Intelligence Scale-Revised (WAIS-R) standardization sample (N=1,880). Analysis of the variance components for each subtest at every age level revealed a substantial proportion of subtests at a wide range of age levels evidenced high or intermediate levels of specific…

Discusses the significance of confidence intervals around IQ scores based on a misleading interpretation of the standard error of measurement terms provided in the Wechsler Adult Intelligence Scale-Revised (WAIS-R) manual. Presents standard error values and a table for determining the abnormality of verbal and performance IQ discrepancies.…

The reliability and stability of the Full Scale IQ scores of retarded adolescents and young adults of three Wechsler Scales were measured. (Author)

Assessed Wechsler Adult Intelligence Scale-Revised test-retest stability for 21 psychiatric and neurological patients. Test-retest interval ranged from 2-144 weeks (x=38 weeks). Subtest stability coefficients were highly significant, yet range of gain or loss for any single individual was comparatively large. Gain or loss was associated strongly…

Reviews the administrative features, uses, development, standardization, reliability, and validity of the Multidimensional Aptitude Battery (MAB), a new group intelligence test designed to be a paper-and-pencil parallel to the Wechsler Adult Intelligence Scale-Revised (WAIS-R). (BL)

From published data on the Wechsler subtest performance of mild and borderline mentally retarded persons, 4,304 protocols from 4,004 individuals were collated and their subtest patterns on other Wechsler instruments were compared. Results indicate that mildly retarded groups tend to score lower on subtests that better measure general intelligence.…

Scaled scores on Wechsler Adult Intelligence Scale subtests were compared among five samples of institutionalized mentally retarded (aged 16 - 71 years) from the east coast (509 Ss), west coast (436 Ss), and three from the midwest (113, 51, and 111 Ss). (Author/PHR)

Results indicate that because there is not an equivalent relationship between the WISC and WAIS, classification or retardation level and prognostic formulation using these tests should be made cautiously. (Author/CB)

Compared the Wonderlic Personal Test and the Wechsler Adult Intelligence Scale for a sample of 30 adults first tested in 1976. The two tests were similar in reliability of clinical classification, but the Wonderlic demonstrated fewer practice effects. Despite its ease of administration, Wonderlic intelligence estimates appear stable. (Author/JAC)
