Exploring Bidirectional Relationships: Child Sleep Duration, Child Behavior Problems, and Parenting Stress in Families of Children with Autism Spectrum Disorder.

Background: Youth with Autism Spectrum Disorder (ASD) are at-risk for sleep and behavior problems, and their parents are at-risk for high stress. Child sleep duration, behavior problems, and parenting stress are interrelated; however, directionality of these associations is unclear and research including youth with ASD is lacking. Using a day-to-day, within-person design, this study explores the directionality of these relationships in families of children with ASD.

Method: Twenty-six children (ages 3-5, 73.1% male, 65.4% Hispanic/Latino) with ASD and their mothers participated in a 14-day study. Child sleep duration (parent-report and actigraphy), behavior problems, and parenting stress were measured daily. Constructs were decomposed into their within- and between-person components and analyzed with random intercept cross-lagged panel models.

Results: While between-person relationships were directionally expected in that shorter sleep, more behavior problems, and greater parenting stress were associated, within-person relationships were complicated. Better-than-average child behavior was associated with less next-day parenting stress, yet more parenting stress than average was associated with better next-day child behavior. As expected, longer-than-average child sleep was associated with less next-day parenting stress, while greater child behavior problems were associated with less sleep that night.

Conclusions: Understanding the directionality of associations between child and parent factors allows for the optimization of interventions to improve the quality of life for families of children with ASD. Interventions that target child behavior and/or help parents manage stress while maintaining effective parenting strategies for sleep and behavior may be useful.
