Evaluation of a behavioral treatment package to reduce sleep problems in children with Angelman Syndrome.
A short parent-run bedtime plan gives kids with Angelman syndrome fast, lasting sleep gains.
01Research in Context
What this study did
Five children with Angelman syndrome took part. All had trouble falling asleep and woke often at night.
Parents followed a three-part plan at home. They set a fixed bedtime and wake time. They changed the bedroom so it was dark, quiet, and calm. They also ignored crying after lights-out and praised quiet behavior.
The team used a multiple-baseline design. They tracked how long each child needed to fall asleep and how many times the child left the bed each night.
What they found
Every child learned to fall asleep on his or her own within a few nights. Night wakings and crying also dropped sharply.
The gains held for the whole study. Parents said they felt less stress at bedtime.
How this fits with other research
Rispoli et al. (2022) later showed parents can learn new skills through Zoom. Their families also saw good results, proving Angelman parents can drive change even from a distance.
Leader et al. (2022) surveyed 98 families and found sleep problems are almost universal in Angelman syndrome. The survey data back up why the bedtime package was needed.
Gee et al. (2020) tried weighted blankets for kids with autism. The blankets gave only tiny sleep gains. The new package works better because it changes behavior instead of just adding weight.
Why it matters
You can copy this package next week. Pick a steady bedtime, remove night-light noise, and teach parents to withhold attention for escape attempts. Track sleep latency and night exits with a simple baseline. Children with Angelman syndrome can master independent sleep fast, and the whole family gains rest.

03Original abstract
The purpose of this investigation was to evaluate the effectiveness of a behavioral treatment package to reduce chronic sleep problems in children with Angelman Syndrome. Participants were five children, 2-11 years-of-age. Parents maintained sleep diaries to record sleep and disruptive nighttime behaviors. Actigraphy was added to provide independent evaluations of sleep-wake activity. The treatment package targeted the sleep environment, the sleep-wake schedule, and parent-child interactions during sleep times. Treatment was introduced sequentially, across families, and evaluated in an interrupted time series, multiple baseline design. Data show that prior to treatment, baseline rates of nighttime disruptive behavior were stable or increasing and none of the participants were falling to sleep independently. With the introduction of treatment, all participants quickly learned to initiate sleep independently. Gradual reductions were reported in disruptive behaviors and these improvements were sustained over time. Results were replicated with two participants when treatment was withdrawn and reinstated. Changes in disruptive bedtime behaviors and in sleep onset were found to be statistically significant. Parents indicated high satisfaction with the treatment. A behavioral treatment package was found to be effective with five children with long histories of significant sleep-related behavior problems. These results suggest that behavioral treatment may be a reasonable way to address sleep problems in some children with Angelman Syndrome.
