The McCarthy Scales of Children's Abilities: Research Implications for the Assessment of Young Children

pp. 319—326

ABSTRACT: A review of the reliability and validity studies of the McCarthy Scales of children’s Abilities (MSCA) shows that the MSCA has excellent reliability and stability; however, its concurrent validity with conventional IQ tests suggest that the McCarthy GCI and IQ are not comparable. Suggestions for future research aimed at delimiting the factors which moderate the GCI-IQ discrepancy were forwarded. The use of the MSCA in the assessment of preschool children was also discussed.
