Insights
Family resources impact child sleep during kindergarten transition. Household chaos mediates this link, affecting sleep duration and recommended sleep proportion.
Area of Science:
- Child development
- Family studies
- Sleep science
Background:
- The transition to kindergarten is a critical developmental period.
- Family socioeconomic status influences child well-being.
- Child sleep is crucial for development and academic success.
Purpose of the Study:
- To investigate the mediational role of household chaos in the relationship between family resources and child sleep outcomes.
- To examine how socioeconomic risk factors affect children's sleep during the kindergarten transition.
Main Methods:
- Longitudinal study of 230 families with children entering kindergarten.
- Data collected via parent-reported scales (Family Resources Scale-Revised) and observer-assessed household chaos (Descriptive In-Home Survey of Chaos-Observer Reported).
- Objective sleep measures (actiwatches) assessed child sleep duration and proportion of recommended sleep.
Main Results:
- Family resources were stronger predictors of child sleep than household income.
- Household chaos mediated the association between family resources and child sleep duration.
- Household chaos also mediated the relationship between family resources and the proportion of recommended sleep.
Conclusions:
- Household chaos is a key mechanism linking family resources to child sleep during the kindergarten transition.
- Addressing household chaos may be important for supporting healthy child sleep in at-risk families.
- Findings underscore the importance of socioeconomic factors in child sleep health.
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.
