We report the case of a 10-year-old boy with autism spectrum disorder who had difficulty initiating and maintaining sleep. Through home consultation, his parents were trained to implement a multicomponent sleep intervention that included (a) faded bedtime, (b) regimented pre-bedtime routines, and (c) elimination of positive social consequences contingent on sleep problems including unwanted co-sleeping. A critical element in the case was functional assessment of the conditions associated with poor sleeping and matching intervention to parent preferences. Compared to a baseline phase, intervention reduced night waking frequency and duration as well as the time required for the boy to fall asleep. Follow-up results one and 2 months post-intervention documented sustained improvement.
