Abstract

The present study examined the factor structure of the Luria interpretive model for the Kaufman Assessment Battery for Children‐Second Edition (KABC‐II) with normative sample participants aged 7–18 (N = 2,025) using confirmatory factor analysis with maximum‐likelihood estimation. For the eight subtest Luria configuration, an alternative higher‐order model with Pattern Reasoning being permitted to cross‐load on the Planning and Simultaneous Processing factors provided the best fit to the normative sample data. Variance apportionment suggests that additional consideration, beyond the omnibus Mental Processing Index, of the contribution of the first‐order factor‐based scores (i.e., SQ, SM, P, and L), and in some cases the individual subtests themselves, may be warranted. Implications for clinical interpretation and the anticipated normative update of the measurement instrument are discussed.
