Sleep problems are frequently reported by parents of children with autism spectrum disorder (ASD), with prevalence estimates of 44-83%. While it is important to address any underlying medical or psychiatric issues that contribute to sleep challenges, establishing good sleep hygiene is considered a good first step, which often includes establishing a consistent bedtime routine. In this study, a visual schedule was used to facilitate compliance with a bedtime routine in a child with ASD. Using an ABAB reversal design, results indicated positive treatment effects, with an increase in bedtime routine compliance during intervention and maintenance of positive effects over time.
