Relationship of the McCarthy Scales of Children's Abilities to other Measures of Preschool Cognitive, Motor, and Perceptual Development

Abstract
The concurrent validity of the McCarthy Scales of Children's Abilities with four other well-known, frequently utilized tests, namely, the Stanford-Binet Intelligence Scale, Developmental Test of Visual-Motor Integration, Goodenough-Harris Drawing Test, and Denver Developmental Screening Test, was examined using 46 preschool children who ranged in age from 2 yr., 8 mo. to 5 yr., 1 mo. Each of the criterion tests includes activities that are present in the McCarthy, and that measure cognitive, motor, and perceptual development. Intercorrelations with other tests were moderately high, with the highest correlation found between the McCarthy General Cognitive Index and the Stanford-Binet IQ. It was concluded that the McCarthy alone is a possible replacement for the more time consuming test battery comprised of the four criterion measures.
