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)

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…

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…

The Peabody correlated significantly with the McCarthy General Cognitive Index, Verbal Scale, Perceptual Scale, and Memory Scale. A significant difference between the means of the two tests was found, with the Peabody yielding lower scores. (Author)

Cross-validated the factor analysis of the McCarthy Scales and determined construct validity for children who score one standard deviation below the normative mean on general cognitive ability. Findings discourage interpretation of the Quantitative Scale for school-age children with General Cognitive Indexes below 84. (Author)

Research supports the reliability and validity of the McCarthy Scales of Children's Abilities (MSCA); but its concurrent validity with conventional intelligence tests suggests that the McCarthy General Cognitive Index and Intelligence Quotient are not comparable. The MCSA eliminates certain weaknesses found in similar tests: the Stanford-Binet and…

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…

This study compares the McCarthy Scales of Children's Abilities (MSCA) and the Kaufman Assessment Battery for Children (K-ABC) profiles of successful and unsuccessful preschoolers with learning disabilities. Subjects, 40 preschool students, were tested at the beginning and at the end of the preschool year and were placed into repeating or…

The instructional components of mediation, a teaching technique used in dynamic assessment, were evaluated with 100 four-year-old children attending daycare or preschools in London, Ontario. The effects of familiarization with task materials, task-specific rule teaching, and elaborated feedback were assessed using a pretest-posttest design.…

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.…

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.…

Children at risk for cognitive difficulties were put in two intervention groups, family and day care education and family education alone, and one control group. Children were tested for cognitive performance. The family and day care group scored higher than other groups. No intervention effects were observed for the family education alone group.…

The purpose and design of a longitudinal study of Project Head Start is summarized in this document, the fourth in a set of ten reports documenting the project. (Material from Project Report 3 was used extensively in preparing this document.) The study was designed to evaluate on a nationwide basis the Head Start Educational Services and to…
