Research Findings: This study investigated the relationships between behavior and attention problems and early language and literacy outcomes for 4-year-olds who experienced varied early home literacy environments. Participants were 1,364 children enrolled in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Attention problems and early home literacy exposure both significantly predicted language and literacy outcomes when relevant covariates were controlled. There was also a significant interaction between behavior and attention problems and early home literacy exposure in predicting expressive language abilities. Specifically, early home literacy exposure was related to more advanced expressive language achievement for children with behavior problems. In contrast, children with attention problems performed below their peers on expressive language measures even when they received comparable early home literacy exposure. Practice or Policy: These findings suggest the need for further research on the differential role of early home literacy exposure on the development of early language and literacy skills in children with behavior and attention problems.
