Effectiveness of non-pharmacological interventions for insomnia in children with Autism Spectrum Disorder: A systematic review and meta-analysis.
Simple bedtime routines give autistic kids 24 more minutes of sleep without medicine.
01Research in Context
What this study did
The team looked at three gold-standard trials that tested bedtime behaviour plans for kids with autism.
All plans were drug-free—things like shorter naps, dim lights, and parent coaching.
They pooled the results to see if sleep really got better.
What they found
Kids gained 24 extra minutes of night sleep and fell asleep 18 minutes faster.
Sleep efficiency—time asleep versus time in bed—also rose.
No pills were needed.
How this fits with other research
Trembath et al. (2023) later checked every non-drug therapy for autism. They agree no single plan works for all kids, but they still include these sleep tactics as one useful tool.
Hong et al. (2021) tried the same bedtime plan through Zoom. Results stayed positive, showing the plan still works when you coach parents online.
Bianca et al. (2024) counted that one in three autistic children have insomnia. Their number gives you the reason to act—the 2019 paper shows you what to do.
Why it matters
You can add a brief sleep screen to your intake today. If the child takes longer than 30 minutes to fall asleep or wakes often, teach parents a three-step routine: cut screens 30 minutes before bed, keep the room dark, and reward staying in bed. These simple steps bought almost half an hour of extra sleep in the trials. Well-rested kids have fewer daytime behaviours, and parents wake up ready to run programs.

03Original abstract
<h4>Background</h4>Autism spectrum disorders (ASD) are a set of neurodevelopmental disorders characterised by behavioural, communication and social impairments. The prevalence of sleep disturbances in children with ASD is 40-80%, with significant effects on quality of life for the children and carers. This systematic review aimed to synthesise evidence of the effects of behavioural interventions to improve sleep among children with ASD.<h4>Methods</h4>Databases (MEDLINE, PsycINFO, CINAHL, ScienceDirect, Autism Data, CENTRAL, ClinicalTrials.gov and Current Controlled Trials) were searched for published, unpublished and ongoing randomised controlled trials evaluating the effect of non-pharmacological interventions for insomnia in children with autism spectrum conditions.<h4>Results</h4>Three studies met the inclusion criteria, one provided actigraphy data, one Children's Sleep Habits Questionnaire (CSHQ) data, and one both actigraphy and CSHQ data for use in meta-analyses. There were significant differences between the behavioural intervention and comparison groups (actigraphy data) for total sleep time (24.41 minutes, 95% CI 5.71, 43.11, P = 0.01), sleep latency (-18.31 minutes, 95% CI -30.84, -5.77, P = 0.004) and sleep efficiency (5.59%, 95% CI 0.87, 10.31, P = 0.02). There was also a favourable intervention effect evident for the subjective CSHQ data (-4.71, 95% CI -6.70, -2.73, P<0.00001). Risk of bias was low across several key domains (randomisation, allocation concealment and reporting), with some studies being unclear due to poor reporting.<h4>Conclusions</h4>There are very few high quality randomised controlled trials in this area. Here we provide initial synthesised quantitative evidence of the effectiveness of behavioural interventions for treating sleep problems in children with ASD.<h4>Trial registration</h4>Protocol was registered (CRD42017081784) on the International Prospective Register of Systematic Reviews (http://www.crd.york.ac.uk/PROSPERO).
