Autistic children are at higher risk of experiencing adverse childhood experiences, which lead to negative health outcomes such as sleep difficulties. In the general population, family resilience can help reduce the negative impact of adverse childhood experiences on child functioning. The aim of this study was to examine the impact of adverse childhood experiences on sleep duration, and whether family resilience moderates this impact in autistic children. With data from 2882 caregivers of children with autism from the National Survey of Children's Health, we examined the role of family resilience on the relationship between adverse childhood experiences and sleep duration. As shown in previous findings, there was a main effect of adverse childhood experiences on sleep duration. There was no significant main effect of family resilience on sleep duration. Results also show that family resilience moderates the relationship between adverse childhood experiences and sleep duration, possibly serving as a protective factor.
