Weighted Blankets and Sleep Quality in Children with Autism Spectrum Disorders: A Single-Subject Design
Weighted blankets gave two preschoolers with autism a slightly faster bedtime and happier mornings, but real sleep fixes still need behavioral plans.
01Research in Context
What this study did
Two preschoolers with autism tried a weighted blanket at bedtime. The researchers used an ABAB design: blanket on, blanket off, blanket on, blanket off.
Parents wrote down how fast the kids fell asleep and how the kids acted the next morning.
What they found
The blanket helped the kids fall asleep a little faster and wake up in a better mood. Overall sleep time and night wakings barely changed.
The gains were too small for the team to recommend the blanket as a real fix.
How this fits with other research
Prigge et al. (2013) got big sleep wins with a full ABA bedtime package for Angelman kids. Their package cut night wakings and taught self-soothing. The tiny gains from Gee’s blanket alone show fabric weight is no match for a behavior plan.
Mutluer et al. (2016) surveyed Turkish families and found long sleep latency is common in ASD. That backdrop makes the few-minute speed-up here look even smaller.
Nasr et al. (2000) warned that parents already rate their autistic kids’ sleep as poor even when duration looks normal. The slight mood lift in Gee’s study may matter most to those parents, even if totals stay flat.
Why it matters
If a family asks about weighted blankets, you can say they are safe but don’t expect magic. Pair the blanket with a real bedtime routine, fading attention, and scheduled awakenings like D et al. did. Track sleep latency and morning mood for two weeks. If you see no clear jump, drop the blanket and move to stronger ABA tools.

03Original abstract
The purpose of the study was to explore the efficacy of weighted blanket applications and sleep quality in children with autism spectrum disorder and behavioral manifestations of sensory processing deficits. Two 4-year-old participants diagnosed with autism spectrum disorder who also experienced sleep disturbances took part in a single-subject design study. Objective sleep measures and caregiver surveys were tracked for a baseline period of eight days, followed by a 14-day weighted blanket intervention and a seven-day withdrawal phase. Caregiver reports and objective data were evaluated using visual analysis and the percentage of non-overlapping data methods. The results suggest minimal changes in sleep patterns as a result of the weighted blanket intervention. The findings based on using a weighted blanket intervention were enhanced morning mood after night use and a significantly decreased time to fall asleep for participants, though they were not strong enough to recommend for clinical use. Future directions include single-subject and cohort-designed studies exploring the efficacy of weighted blankets with increasing sleep quality among children with autism.
