Is it Prudent to Administer All Items for Each Child Behaviour Checklist Cross Informant Syndrome? Evaluation of the Psychometric Properties of the Youth Self Report Dimensions via Conformatory Factor Analysis and Item Response Theory
Date of Publication
Through surveying of children in 10 nations with parent, teacher, and Youth Self-Report (YSR) forms of the Child Behaviour Checklist (CBCL), cross-informant syndromes (CISs) were derived and cross-validated by sample-dependent methodology. Generalizing CBCL syndromes and norms to nations excluded from its normative sample is problematic. This study used confirmatory factor analyses (CFAs) to test factor model fit for CISs on the YSR responses of 625 Jamaican children ages 11 to 18 years. Item response theory (IRT), a sample-independent methodology, was used to estimate the psychometric properties of individual items on each dimension. CFAs indicated poor to moderate model-to-data fit. Across all syndromes, IRT analyses revealed that more than 3/4 of the cross-informant items yielded little information. Eliminating such items could provide a more efficient behaviourial model.....
