Examined the standard error for short forms of Wechsler's scales with deviant subjects (N=2000). Demonstrated that the standard error of estimate of a short form for the standardization sample is an excellent approximation to the standard error of a predicted IQ for a new, even markedly deviant, subject.

The intercorrelations among the twelve subtests of the WISC were analyzed for each of eleven age groups in the standardization sample, using the principal factor method. Both the two and three factor solutions are assessed using the coefficient of congruence. (Author/JKS)

The four items on the scale that favored the Down syndrome Ss all involved figural content and visual-motor ability. The five items that favored the non-Down syndrome Ss generally involved semantic content, social intelligence, general comprehension, and/or judgment and reasoning. (Author/SB)

Examines the consequences of regarding Deviation Quotients (DQs) as estimates of Full Scale IQs. Offers a new formula and shows the increase in error to be negligible for short forms with typical validities, which supports linear scaling as an acceptable alternative to linear regression. (LLL)

Addresses the question of abnormality when comparing a subject's score on each subtest with that subject's average subtest score on one of Weschler's scales. Suggests comparing each subtest score with the Verbal or Performance average rather than with the overall average. Provides tables estimating differences of standardization samples. (BH)

The performance of 101 educable mentally retarded children on four annual administrations of the Stanford-Binet Intelligence Scale was analyzed using J. Sattler's standard deviation method and his Bintegram. Few of the children showed strengths and weaknesses until the original criteria were relaxed, and even then there was little stability over…

Compared factor structures of the WISC and the WISC-R using the data for age groups 7.5, 10.5, and 13.5 years in the two standardization samples. Results demonstrated that the structures of the two scales are as similar as the structure of either scale is for different age groups. (Author)

Proposes Vocabulary and Block Design as a two-subtest short form of the Wechsler Adult Intelligence Scale-Revised; the addition of Arithmetic and Picture Arrangement provides a four-subtest short form of the scale. Presents tables giving Full Scale IQs for each of nine age groups for both short forms. (Author)

The intercorrelations among the 12 subtests of the WISC-R were analyzed for each of the 11 age groups in the standardization sample. Clusters were found that corresponded to the verbal and performance Scales. There was also some evidence of a third group of subtests, drawn from both scales. (Author/BW)

Data from the WAIS, WISC, and WPPSI Standardization samples were used to reappraise validity of all short forms of two, three, four, and five subtests. Results were compared with those given by McNemar's formula. The corrected formula gave lower values and selected "best short forms that differed from McNemar's formula. (Author)

Formulas for estimating the validity of random short forms were applied to the standardization data for the Wechsler Adult Intelligence Scale-Revised, the Minnesota Multiphasic Personality Inventory, and the Marlowe-Crowne Social Desirability Scale. These formulas demonstrated how much "better than random" the best short forms of these…

Subjected the standardization data for the Wechsler Adult Intelligence Scale-Revised (WAIS-R) and the original Wechsler Adult Intelligence Scale (WAIS) to principal-factor analysis. A two-factor solution was adopted for each scale. The stability of the two factors, Verbal Comprehension and Perceptual Organization, was high both within and between…

Correlations with Binet IQ in the ITPA normative sample were corrected for restricted intelligence range. The corrected correlation for the Psycholinguistic Quotient is as high as that between the WISC and the Binet, a finding that raises a serious question about the construct validity of the ITPA. (Author)

Assessed the validity of short forms that reduce the number of items within subtests rather than the number of subtests. Used data from the standardization samples for the Wechsler Intelligence Scale for Children, Wechsler Adult Intelligence Scale, Wechsler Preschool and Primary Scale of Intelligence, WISC-Revised, and WAIS-Revised.
