The factor structure of the CIBS-II-readiness assessment

摘要

The Brigance Comprehensive Inventory of Basic Skills-II (CIBS-II)-Readiness form is a diagnostic battery intended for children aged 5 and 6 years. The CIBS-II-Readiness is a new version of the CIBS-Revised-Readiness and includes updated normative information on a larger representative sample in comparison to the CIBS-Revised-Readiness. Empirical support for the CIBS-Revised-Readiness was lacking, especially score validity evidence. Adequate score validity information needs to be provided. The purpose of this study was to investigate evidence of construct validity of the composite scores on the CIBS-II-Readiness by examining the internal structure of the instrument and correlations with external measures. Confirmatory factor analysis was employed to compare the model implied by the composite score structure of the assessment to other plausible models. A six-factor model was supported. CIBS-II-Readiness scores had significant correlations with the Dynamic Indicators of Basic Early Literacy Skills scores, another widely used measure assessing five major components of early literacy.
