A Comparison of the WISC-R, McCarthy Scales, Woodcock-Johnson, and Academic Achievement: Concurrent and Predictive Validity.
Drudge, Owen W.; And Others
Thirty normal first-grade students with a mean age of 7.0 years were administered the Wechsler Intelligence Scale for Children-Revised, the McCarthy Scales of Children's Abilities, and the Woodcock-Johnson Tests of Cognitive Ability. Pearson intercorrelations among the summary indices of these cognitive measures were uniformly high, ranging from .78 to .94. Mean differences were not found between the three full scale indices. However, the short form index of the Woodcock-Johnson was found to be a consistent, significant underestimate of the full scales. Academic achievement was measured by the Wide Range Achievement Test and teacher ratings. Correlations between the cognitive and achievement measures were significant in all cases. Although striking differences were not apparent, the Woodcock-Johnson indices proved to correlate slightly better with achievement. Partial correlations between the Wide Range Achievement Test and teacher ratings were likewise all significant and were ordered in a manner that would suggest that the two sets of scales measured similar domains.
