Parent-Child Shared Book Reading Mediates the Impact of Socioeconomic Status on Heritage Language Learners' Emergent Literacy.

The promotion of parent-child shared book reading for the development of children's literacy is a vital component of early literacy evidence-based recommendations. A robust body of research demonstrates that, regardless of socioeconomic status, parent-child shared book reading promotes monolingual children's literacy. However, despite the growing population of heritage language learners in the United States, those who grow up in homes where a familial language is spoken but receive English instruction at school, parent-child shared book reading research among heritage language learners remains scarce. Further, the impact of parent-child shared book reading is likely to alter the influence of family's socioeconomic status on heritage language learners' emergent literacy development. Here, parent-child shared book reading and children's emergent literacy were examined using latent variable path analyses in a national sample of 965 heritage language learners ages 2 to 6 years old. Parent-child shared book reading mediated the effect of socioeconomic status on heritage language learners' emergent literacy.
