Behavioural interventions for sleep problems in people with an intellectual disability: a systematic review and meta-analysis of single case and group studies.
Behavioral sleep fixes work fast for people with ID, but add booster sessions to keep night-time waking away.
01Research in Context
What this study did
The team hunted for every paper that tested behavioral sleep help for people with intellectual disability. They found seven studies that tracked 169 participants in total.
Each study used single-case or small-group designs. The review pooled the numbers to see how big the sleep gains really were.
What they found
Sleep came faster and stayed longer right after treatment. The overall effect size was large, but the win faded faster for kids who kept waking up in the night.
In plain words: bedtime routines and brief extinction plans work great at first. You just need booster sessions to keep the gains.
How this fits with other research
Lippold et al. (2009) showed the same quick sleep wins in adults living in group homes. Taylor et al. (2017) now proves the pattern holds across kids and adults.
Nuebling et al. (2024) looked at sleep in ID without trying any fix and found shorter, worse sleep than typical. That bad baseline makes the large gains in Taylor et al. (2017) even more striking.
Garayzábal et al. (2022) reported that most youth with Smith-Magenis syndrome have both sleep and behavior issues. Taylor et al. (2017) gives you the toolkit to tackle the sleep side first, which often calms the behavior side too.
Why it matters
You now have meta-level proof that simple behavioral plans—like faded bedtime, response cost, or brief extinction—give fast, large sleep gains for clients with ID. Schedule follow-up visits at 2 and 6 weeks to lock in the win, especially for clients whose main problem is night waking.

03Original abstract
BACKGROUND: Behavioural interventions are frequently used to address sleep problems in people with intellectual disabilities (ID). The current study aimed to systematically review evidence on the efficacy of behavioural interventions for children and adults with ID and sleep problems. METHOD: Electronic and hand searches identified seven studies for inclusion (N = 169). Standardised mean difference effect sizes (d) were calculated for group studies (N = 4). Non-overlap effect sizes (Tau-U) were calculated for single case experimental design studies (SCEDs; N = 3). RESULTS: A large effect size (weighted d = 0.923, confidence interval: 0.705 to 1.151) across group studies indicated large improvements in sleep problems following behavioural intervention. Effect size across SCEDs (weighted Tau-U: 0.528, confidence interval: 0.351 to 0.705) indicated a 53% improvement compared with baseline. Sleep initiation and sleep maintenance problems showed significant improvements post-intervention. Follow-up effects were less consistent across study designs and suggested that some sleep problems maintain gains better than others. CONCLUSION: Meta-analytic evidence from group and SCEDs can provide complementary information about efficacy. Findings propose that behavioural interventions are a promising evidence-based practice for improving sleep problems in people with ID.
