title: Exploratory Higher Order Analysis of the Luria Interpretive Model on the Kaufman Assessment Battery for Children-Second Edition (KABC-II) School-Age Battery.
abstract: Higher order factor structure of the Luria interpretive scheme on the Kaufman Assessment Battery for Children-Second Edition (KABC-II) for the 7- to 12-year and the 13- to 18-year age groups in the KABC-II normative sample ( N = 2,025) is reported. Using exploratory factor analysis, multiple factor extraction criteria, and hierarchical exploratory factor analysis not included in the KABC-II manual, two-, three-, and four-factor extractions were analyzed to assess the hierarchical factor structure by sequentially partitioning variance appropriately to higher order and lower order dimensions as recommended by Carroll. No evidence for a four-factor solution was found. Results showed that the largest portions of total and common variance were accounted for by the second-order general factor and that interpretation should focus primarily, if not exclusively, at that level of measurement.
