Increasing the Reliability of Ability-Achievement Difference Scores: An Example Using the Kaufman Assessment Battery for Children.
Caruso, John C.; Witkiewitz, Katie
Journal of Educational Measurement, v39 n1 p39-58 Spr 2002
As an alternative to equally weighted difference scores, examined an orthogonal reliable component analysis (RCA) solution and an oblique principal components analysis (PCA) solution for the standardization sample of the Kaufman Assessment Battery for Children (KABC; A. Kaufman and N. Kaufman, 1983). Discusses the practical implications of the increased reliability with which KABC scores are assessed with the orthogonal RCA method. (SLD)
