622 Bedtime, Sleep Duration, and Sleep Quality as Predictors of Externalizing Symptoms in Children in Foster Care

Abstract

Abstract Introduction A strong association between sleep disturbances and externalizing symptoms has been found among school-aged children. In particular, there is a known association between sleep disturbances, irritability, emotional dysregulation, and hyperactivity (e.g., Coto et al., 2018). Limited research, however, has examined this association in a high-risk population of children, such as those in foster care who are at increased risk for sleep disturbances due to heightened exposure to trauma. Thus, the following study sought to assess the association between sleep quality and externalizing symptoms in a population of children in foster care. Methods Caregivers with children ages 4–11 were sampled from private Facebook community foster care groups across the United States (n = 410). Caregivers were provided a link to a survey powered by Qualtrics where they were asked to report on the children under their care’s weekday bedtime, overall sleep quality (e.g., “Please rate your child’s overall sleep quality over the last two weeks”), and sleep onset (e.g. “On weekdays, how long does it usually take for your child to fall asleep?”). Child behavioral issues were assessed via the Eyberg Child Behavior Inventory (ECBI) Parent Rating Form. Results A linear regression model was utilized to assess if child weekday bedtime, weekday total sleep duration, and overall sleep quality were unique predictors of externalizing symptoms when controlling for age. Results suggest that weekday sleep duration and bedtime were not significant unique predictors of child behavioral issues, though were significantly and positively correlated at the bivariate level (p=.02, p=.04). Sleep onset and overall sleep quality, irrespective of child age, were found to be significant unique predictors of child behavioral issues and accounted for 1% and 11% of the total variance, respectively. Conclusion Results suggest that delayed sleep onset and poorer sleep quality were predictive of increased behavioral issues for children in foster care. Findings persisted when controlling for age, which suggests that children in foster care experiencing sleep disturbances may benefit from more behaviorally focused sleep interventions to improve externalizing behaviors and increase sleep health.
