It was found that the General Cognitive Index scores of the McCarthy Scales correlated well with the Stanford-Binet IQ scores. However, 40 of the 44 subjects scored higher on the Stanford-Binet than on the McCarthy Scales. (Author)

This study evaluates the reliability of profile analysis for assessing differential abilities on the McCarthy Scales for Children's Abilities (MSCA). Subjects were enrolled in private schools. Results indicated 70.9 percent of the sample showed profile variability not reasonably accounted for as real fluctuations in measurable abilities. (Author)

Concurrent validity of the McCarthy Scales of Children's Abilities for 60 kindergartners was investigated, using the WPPSI and Columbia Mental Maturity Scale. Although correlations were of acceptable magnitude, the General Cognitive Index of the MSCA was significantly lower than major scores obtained on the other two tests. (Author)

Assessed the degree of comparability between the McCarthy Scales of Children's Abilities (McCarthy) and the Kaufman Assessment Battery for Children (K-ABC) for "at-risk" (low birthweight, Head Start, and developmentally delayed) and "normal" preschool children. Describes the K-ABC Mental Processing Composite (MPC) and McCarthy…

First graders (N=26) completed the Wechsler Intelligence Scale for Children-Revised, McCarthy Scales, and Woodcock-Johnson Scales of Cognitive Ability. Two years later, their academic achievement was determined by Wide Range Achievement Test and teacher ratings. Results suggest that all three intellectual measures are appropriate for predicting…

Compared the performance of 21 moderately mentally retarded children on the McCarthy Scales of Children's Abilities (MSCA), Stanford-Binet, and Minnesota Child Development Inventory (MCDI). Mental age estimates from the three measures correlated significantly, but valid MSCA Index scores could not be obtained. (JAC)

Examine the predictive validity of Kaufman's short form of the McCarthy Scales of Children's Abilities for 74 Mexican-American children. Comparisons between the McCarthy General Cognitive Index (GCI) and Kaufman's estimated CGI with academic achievement showed that the conventional McCarthy and Kaufman's short form predicted achievement about…

Cross-validated the factor structure of the McCarthy Scales of Children's Abilities for 105 kindergarten children. A factor analysis generated five factors, including Verbal Comprehension, Quantitative-Reasoning, Memory, Perceptual-Performance, and Motor factors. The overall factor pattern provides further evidence of the construct validity of the…

Performed a follow-up of a sample of children (N=24) to determine whether the McCarthy Scales administered during kindergarten is predictive of subsequent achievement test performance and predictive of course grades during the sixth grade. Results indicated that the McCarthy Scales have predictive value over a six-year period. (LLL)

Scatter on the five specific scales in the McCarthy was examined to explore the types of ability profiles exhibited by normal children. Contrary to the common stereotype of "flat" profiles, normal children aged 2-1/2 to 8-1/2 years evidenced much variability in their performance on the various cognitive and motor dimensions. (Author)

Compared the Peabody Picture Vocabulary Test and McCarthy Scales of Children's Abilities for 35 preschool children identified as being "at risk." Nonsignificant differences were found between Forms L and M of the PPVT-R and the McCarthy GCI.Correlations between the PPVT-R and the McCarthy GCI and Scale scores were significant. (Author)

Examined the efficacy of the McCarthy Scales as a predictor of reading readiness and achievement in a kindergarten sample (N=33). Results confirmed the predictive validity of the McCarthy Scales and suggested that, for this sample, visual discrimination and sequential ability skills may have been more important factors than verbal abilities.…

Examined the relationships between the McCarthy Scales General Cognitive Index, the McCarthy Screening Test, Kaufman's McCarthy short form, and the Peabody Individual Achievement Test using a sample of elementary students. Found the Estimated General Cognitive Index by Kaufman's short form was virtually identical to the McCarthy Scales Index.…

Scores on Kaufman's (1977) McCarthy short form and the McCarthy Screening Test (1978) were obtained for first graders (N=53). As follow-up nine months later, the Metropolitan Achievement Test was administered. Results showed Kaufman's short form scores usually indicated a smaller number of false negatives than did McCarthy Screening Test scores.…

Developed a system of tables to facilitate interpretation of the McCarthy Scales of Children's Abilities. Presents tables that organize the McCarthy subtests according to three systems of interpretation, and organize McCarthy Scales into categories that reflect factors likely to influence various subtests.
