Concurrent validity of the PPVT-R with the K-ABC for learning problem children

This study examined the concurrent validity of the Peabody Picture Vocabulary Test-Revised (PPVT-R) and the Kaufman Assessment Battery for Children (K-ABC) with 47 students referred for learning difficulties. A comparison of the correlations of each of the criterion measures from the K-ABC global scales showed a more substantial relationship between the PPVT-R standard score and the K-ABC Achievement scale than with other K-ABC scales. In an effort to further examine the relationship between the PPVT-R and the K-ABC, a stepwise multiple regression was calculated, with the standard scores of the K-ABC global scales serving as the predictor variables of the PPVT-R. This analysis indicated that the K-ABC Achievement global scale was the only significant predictor of the PPVT-R. Implications for practitioners were discussed.
