Abstract
The aim of this study was to examine the relationship between the McCarthy Scale of Children's Abilities and the Kaufman Assessment Battery for Children for a sample of 51 normal children. Results revealed no significant difference between the McCarthy General Cognitive Index and the K-ABC Mental Processing Composite (t = .55, p > .10), and these scores correlated significantly (r = .55, p = .001). The predictive validity of these instruments was examined using the Peabody Individual Achievement Test (administered after a three-month interval). Multiple regression analyses revealed that the K-ABC Achievement scale was the best predictor of PIAT Total scores (R = .75), and none of the remaining K-ABC or McCarthy scales added significantly to the prediction. Implications of these and other findings are discussed.Keywords
