The association between home chaos and academic achievement: The moderating role of sleep.

The goal of this study was to understand the role young children's sleep plays in the association between their family environment and academic achievement (AA) by examining sleep as a moderator between home chaos (chaos) and children's AA. We examined this question in a sample of 103 kindergarteners and 1st graders. In the fall, parents reported on levels of chaos in their home. To measure sleep, early in the spring, children wore actigraphs for 5 consecutive school nights. Later in the spring, children completed standardized tests of achievement. Sleep duration, but not sleep efficiency, moderated relations between chaos and AA. Specifically, children with longer sleep durations (26% of the sample), compared to children with average or lower sleep durations, had significant negative associations between chaos and achievement, indicating that children in higher chaos homes had lower academic achievement. The findings enhance scholars' understanding of the relation between chaos and AA as well as highlight an important bioregulatory factor in the association between home family environment and children's academic outcomes.
