Principal factor solutions to the WISC-R were compared across race for Anglo and Chicano children. Additional comparisons of factor solutions were made with those for Anglo, Chicano, Black, and Papago students and the WISC-R standardization sample. Substantial congruence occurred across race. The two-factor solution was most appropriate for this…

Forty trainable mentally retarded students were concurrently administered the Stanford Scale and the Wide Range Achievement Test (WRAT). WRAT reading, spelling and arithmetic subtests were regressed on Stanford intelligence quotients. Predictions were statistically valid. Derived regression equations are reported. (Author/CP)

The Wechsler Preschool and Primary Scale of Intelligence (WPPSI) was factor analyzed at each of six age levels between four and six-plus years through the method of principal factors. Results substantially support Wechsler's division of the WPPSI subtests into a Verbal and a Performance scale at all age levels. (Author)

Regression lines for the prediction of achievement were compared across race through the Potthoff analysis, which provides a simultaneous test of slope and intercept values. Results of these comparisons generally supported the predictive validity of the Wechsler Intelligence Scale for Children-Revised across race with this referral sample of young…

Describes a method using age equivalents and standard scores to recreate the full range of variability in the scores of high-functioning individuals. The method allows for a more complete interpretation of performance that can lead to better educational and therapeutic programing. (Author/ABB)

The author empirically evaluates bias in construct validity and criterion-related validity of intelligence tests and bias in personality scales and concludes that little evidence exists to substantiate claims of bias for well-constructed, properly standardized tests. Therefore,, low-scoring minority or disadvantaged children need remedial and…

Correlations of WPPSI IQs with concurrently administered subtests from the WRAT were compared with analogous WISC-R/WRAT correlations in a group of children referred by regular classroom teachers for school psychological services. Results support the use of the two instruments as equivalent predictors of achievement. (Author)

Regression lines for the prediction of Wide Range Achievement Test (WRAT) standard scores by Stanford-Binet Intelligence Scale scores were compared across race for matched groups of 60 black and 60 white children selected from among a large number of children who had been referred for psychological services by their classroom teachers. The white…

Groups of 270 Black and 270 White children drawn from the national stratified random sample used in the standardization of the Wechsler Intelligence Scale for Children-Revised (WISC-R) were matched on age, sex, and WISC-R Full-Scale Intelligence Quotient to facilitate investigation of the patterns of specific cognitive abilities. (Author)

Predictive validity of the Weschler Intelligence Scale for Children-Revised (WISC-R), was investigated with 174 Chicanos and 94 Anglos, ages 10-11, who were referred for psychological services. Wide Range Achievement Test Reading, Spelling, and Arithmetic subtest scores were each regressed on WISC-R Verbal, Performance and Full Scale Intelligence…

Analyzed data from standardization sample of 1981 Wechsler Adult Intelligence Scale-Revised (WAIS-R) to determine relationships of WAIS-R intelligence quotients (IQs) to demographic variables upon which sample was stratified. Found significant differences in mean IQs due to race and education level; sizeable differences for occupational groups;…

Wechsler Preschool and Primary Scale of Intelligence (WPPSI) and McCarthy Scales subtests were ranked according to relative reliance on left-cerebral-hemisphere function. Results suggest that black-white IQ discrepancies may be partially explained by differences in hemisphericity. (Author/RD)

To test the validity of the Wechsler Intelligence Scale for Children-Revised (WISC-R) for minority groups, factorial similarity across race was investigated with separate principal-factor analyses for White and Black children from the nationally representative WISC-R standardization sample. On every measure, the White and Black groups were highly…

Raw scores on WISC-R subtests and the verbal, performance, and full scale IQ scales were correlated with age separately for White and Black males and females. The relationship between age and intelligence test performance was constant across race and sex and supports the construct validity of the WISC-R. (Author/RD)

Regression lines for the prediction of Wide Range Achievement Test (WRAT) scores by Wechsler Intelligence Scale for Children (WISC) and WISC Revised (WISC-R) intelligence quotients were compared across race, by the Potoff technique. Subjects were 36 black and 30 white children who were referred for psychological evaluation because of learning or…
