Concurrent validity of McCarthy's Scales.
Data on the concurrent validity of the McCarthy Scales of Children's Abilities, using the Wechsler Preschool and Primary Scale of Intelligence and the Wechsler Intelligence Scale for Children-Revised as the criteria, were compared with those of other studies. In the present work 40 children were given the McCarthy scales and one of the Wechsler scales depending on the age of the child. Significant moderate to strong correlations at the preschool and school-age levels between the General Cognitive Index of the McCarthy and Wechsler's IQs were noted.
