Dimensionality of Oral Language in Bilingual 6th Grade Children

Document Type


Publication Date



We examined the dimensionality of oral language in Spanish-English bilingual 6th-grade children. Research indicates that oral language in bilingual children is multidimensional (LARRC, 2015). However, dimensionality may differ by age and the measures used. Few studies have included pragmatic skills or studied the structure of oral language in Spanish-English bilingual adolescents. We conduct confirmatory factor analyses (CFAs) on a sample of 95 bilingual 6th-grade children to test oral language models with one to four (grammar, vocabulary, listening comprehension, and pragmatics) underlying factors, as well as bifactor and hierarchical models that include a general factor. In addition, we test two models with language-specific factors. Model parameters and appropriate fit statistics, including chi-square difference tests for nested models, are presented to aid in judging the adequacy of alternative models. The study is preregistered, and the data are collected and cleaned.
