Sleep and Behavioral Problems in Children with Autism Spectrum Disorder.
Night awakenings are the sleep problem most tightly linked to daytime aggression and irritability in kids with ASD—screen and target them first.
01Research in Context
What this study did
Kellems et al. (2016) asked parents of 81 children with autism about sleep and daytime behavior.
They used surveys to see which sleep issues best explained aggression, irritability, inattention, and hyperactivity.
No treatment was given; they simply tracked what was already happening.
What they found
Night awakenings stood out as the biggest driver of daytime problems.
Sleep issues overall explained about one-quarter of the variance in aggression and irritability.
In short, broken nights meant rougher days.
How this fits with other research
McGarty et al. (2018) flipped the direction: they showed that early aggression predicts later sleep problems.
Taken together, the two studies reveal a loop—poor sleep fuels aggression, and aggression then worsens sleep.
Berenguer et al. (2024) extended the link to communication, finding that sleep problems also mediate language deficits in children with both autism and ADHD.
Tse et al. (2019) showed you can break the loop: thirty minutes of weekday physical activity improved sleep efficiency and next-day self-control in an RCT.
Why it matters
Start every assessment with one quick parent question: “Does your child wake during the night?” If the answer is yes, target those awakenings first. Better nights can trim aggression, boost attention, and even support communication gains. Pair sleep plans with daytime movement programs to hit the cycle from both ends.

03Original abstract
Children with autism spectrum disorder (ASD) are at high risk for sleep disturbance and behavioral dysregulation. However, the relationships between these difficulties are not fully understood. The current study examined the relationships between specific types of sleep and behavioral problems among 81 children with ASD. Sleep problems were significantly associated with physical aggression, irritability, inattention, and hyperactivity. In multivariate analyses, distinct sets of sleep problems accounted for between 22 and 32 % of the variance in behavior problems across models. These results indicate that sleep disturbance is associated with behavioral dysregulation among children with ASD. Of note, night awakenings had the most consistently strong association with daytime behavior problems, even after controlling for the effects of age and sex.
