Correlates and risk markers for sleep disturbance in participants of the Autism Treatment Network.
Anxiety, sensory issues, and GI pain are the clearest red flags for sleep problems in autistic kids—screen these first.
01Research in Context
What this study did
The team looked at a big group of autistic children in the Autism Treatment Network. They wanted to find which child traits most often show up with sleep problems.
Parents filled out forms about sleep, anxiety, sensory issues, stomach pain, and behavior. The study used stats to see which items best predicted poor sleep.
What they found
Anxiety, sensory sensitivities, and GI pain were the clearest red flags for sleep trouble. These links were small to medium, but they showed up again and again across kids.
How this fits with other research
Storch et al. (2012) already showed that shorter sleep predicts lower IQ and weaker daily-living skills in autistic kids. The 2013 paper widens the lens by naming anxiety, sensory, and GI issues as the top warning signs.
Rzepecka et al. (2011) used the same network and found that sleep plus anxiety explains nearly half of challenging behavior. The 2013 results support that link and add GI and sensory items to the watch list.
Altun Varmis et al. (2026) later showed that sensory processing problems mediate the link between screen time and poor sleep. This builds on the 2013 finding that sensory issues matter, and it points to a treatment target: sensory modulation, not just screen limits.
Why it matters
When an autistic client is not sleeping, first ask about anxiety, sensory triggers, and stomach pain. These three areas give you the fastest route to a plan: add calming routines, adjust sensory input before bed, and rule out GI discomfort. Treating sleep here can also lower parent stress and next-day behavior problems.

03Original abstract
We explored possible cognitive, behavioral, emotional, and physiological risk markers for sleep disturbance in children with autism spectrum disorders. Data from 1,583 children in the Autism Treatment Network were analyzed. Approximately 45 potential predictors were analyzed using hierarchical regression modeling. As medication could confound findings, it was included in the analyses as a covariate. Results revealed that anxiety, autism symptom severity, sensory sensitivities, and GI problems were associated with sleep disturbance. IQ positively predicted sleep disturbance, and children with Asperger's Disorder were more vulnerable than others. The amount of variance in sleep outcomes explained by predictor variables was modest (i.e., R (2) from .104 to .201). Predictor variables were evaluated in the context of a bidirectional theoretical framework.
