Home literacy: Opportunity, instruction, cooperation and social-emotional quality predicting early reading achievement

IN THIS prospective study home literacy is considered a multifaceted phenomenon consisting of a frequency or exposure facet (opportunity), an instruction quality facet, a parent-child cooperation facet, and a social-emotional quality facet. In a multiethnic, partly bilingual sample of 89 families with 4-year-old children, living in inner-city areas in the Netherlands, measures of home literacy were taken by means of interviews with the parents and observations of parent-child book reading interactions when the target children were ages 4, 5, and 6 years. Ar age 7, by the end of Grade 1, after nearly 1 year of formal reading instruction, vocabulary, word decoding, and reading comprehension were assessed using standard tests. Vocabulary at age 4 and an index of the predominant language used at home were also measured in order to be used as covariates. Correlational and multiple regression analyses supported the hypothesis that home literacy is multifaceted. Home literacy facets together predicted more variance in language and achievement measures at age 7 than each of them separately. Structural equations analysis also supported two additional hypotheses of the present research. First, the effects of background factors (SES, ethnicity, parents' own literacy practices) on language development and reading achievement in school were hilly mediated by home literacy, home language, and early vocabulary. Second, even after controlling for the effects of early vocabulary and predominant home language, there remained statistically significant effects of home literacy, in particular, opportunity, instruction quality, and cooperation quality.
