Randomised Controlled Trial of a Behavioural Sleep Intervention, 'Sleeping Sound', for Autistic Children: 12-Month Outcomes and Moderators of Treatment

This study examined the sustained and moderating effects of a behavioural sleep intervention for autistic children in a randomised controlled trial. Autistic children (5-13 years) with sleep problems were randomised to the Sleeping Sound intervention or Treatment as Usual (TAU). At 12-month follow-up (n = 150), caregivers of children in the Sleeping Sound group reported greater reduction in child sleep problems compared to TAU (p < .001, effect size: - 0.4). The long-term benefits of the intervention were greater for children taking sleep medication, children of parents who were not experiencing psychological distress, and children with greater autism severity. The Sleeping Sound intervention demonstrated sustained improvements in child sleep. Identified moderators may inform treatment by indicating which subgroups may benefit from further support.

Automated summary

The study examined the long-term and moderating effects of a behavioral sleep intervention for autistic children. The intervention showed sustained improvements in child sleep, with greater reduction in sleep problems reported by caregivers compared to the control group. The benefits were found to be greater for children taking sleep medication, children of parents without psychological distress, and children with greater autism severity. These findings can inform treatment decisions and identify subgroups that may require additional support.
