Repetitive behaviors in autism and obsessive-compulsive disorder: new perspectives from a network analysis.
Sensory interests form the shared bridge between autism and OCD symptom networks.
01Research in Context
What this study did
Sparaci et al. (2015) built a map of symptoms. They used network analysis. This tool shows which symptoms talk to each other.
The map included people with autism and people with OCD. The team looked at repetitive behaviors. They wanted to see which behaviors sit close together.
What they found
Two clear clusters showed up. One cluster held autism-type repetitions. The other held OCD-type repetitions.
Sensory interests sat between the two groups. These interests acted like a bridge. They linked the autism cluster to the OCD cluster.
How this fits with other research
Rojahn et al. (2012) looked at autism and anxiety. They found that insistence on sameness links to anxiety only in kids who are already anxious. Laura’s network adds detail. It shows sensory interests, not sameness, as the shared bridge.
Byiers et al. (2025) used the same network tool. They added personality traits. Their map shows personality at the center. Laura’s map shows sensory interests at the center. The methods match, but the spotlight moved.
Flygare et al. (2020) tested therapy. They gave adapted CBT to autistic adults with OCD. About one in six reached remission. Laura’s bridge finding hints at why therapy is hard. If sensory interests glue the two disorders, you may need to target that bridge first.
Why it matters
When you see sensory interests in a client, look both ways. They may signal autism-only repetitions, or they may flag OCD-style rituals. Probe for hidden compulsions. Track data on sensory play and ritual length. Targeting the sensory bridge could loosen both clusters at once.

03Original abstract
The association between autism and obsessive-compulsive disorder (OCD) seems largely dependent upon observed similarities in the repetitive behaviors that manifest in both disorders. The aim of this study was to use a network approach to explore the interactions between these behaviors. We constructed a network based on clinician's perceptions as well as a network based on 213 clinically diagnosed children. In all networks, autism and OCD emerged as two distinct symptom clusters and obsessions and compulsions showed few direct associations with autism symptoms. Further, sensory interests were identified as behaviors that may contribute to the link between autism and OCD. Through network analysis, we expose the symptom pathways that may lead to the perceived association between autism and OCD.
