Household chaos mediates the link between family resources and child sleep

Purpose: This study examined the mediational role of household chaos in the link between family resources and child sleep outcomes during the transition to kindergarten. Procedures: Participants included 230 families of children entering kindergarten (50% female) who participated in an 8-day measurement burst at pre-kindergarten (July-August), early kindergarten (September/ October), and mid-kindergarten (November/December). At pre-kindergarten, mothers completFed the Family Resources Scale-Revised (FRS-R), while at pre- and early-kindergarten, trained observers assessed household chaos using the Descriptive In-Home Survey of Chaos-Observer ReporteD (DISCORD). To better understand perturbations in child sleep during this transition, actiwatches (AW Spectrum Plus, Philips/ Respironics, Murrysville, PA) were used to measure both child sleep duration and proportion of recommended sleep duration (9+ hours per night) at early- and mid-kindergarten. Main findings: Results found that family resources were more clearly predictive of child sleep outcomes than household income. Controlling for quality of coparenting and maternal depressive symptoms, household chaos mediated the link between family resources and child sleep duration at both early and mid-kindergarten, the link between family resources and the proportion of recommended sleep duration in mid-kindergarten, and the change in proportion of recommended sleep from pre-kindergarten to early-kindergarten. Conclusions: Findings highlight household chaos as a mechanism by which family resources, a metric of socioeconomic risk, influences child sleep during the transition to kindergarten.
