Network Analysis of Anxiety in the Autism Realm.
In high-functioning autism, anxiety sits at the edge of the symptom web and links up like it does in typical kids.
01Research in Context
What this study did
Montazeri et al. (2019) built network maps of autism traits. They asked if anxiety sits in the middle or at the edge.
Kids with high-functioning autism answered checklists. The team drew lines between every symptom pair.
What they found
Anxiety items landed on the fringe of the web. They did not cluster with core autism traits.
The anxiety links looked the same as in typical kids. Same shape, different kids.
How this fits with other research
Lo et al. (2021) extends this view into adult brains. fMRI shows weak insula links relate to higher anxiety in middle-aged autistic adults.
Cullinan et al. (2001) is the predecessor. They first showed high anxiety in this group years ago.
Adams et al. (2020) add a twist. Almost every autistic child self-reports anxiety, yet adults often miss it at school. This seems to clash with anxiety being "peripheral," but the network study looked at symptom structure, not adult awareness.
Why it matters
Treat anxiety as a separate module, not part of core autism. You can target it without touching social or repetitive traits. Screen with child-friendly tools and plan CBT or exposure sessions that follow typical anxiety protocols. Check for sensory avoiding if progress stalls.

03Original abstract
The anxiety and autism realms are each complicated and heterogeneous, and relationships between the two areas are especially complex. Network analysis offers a promising approach to the phenotypic complexities of typical and atypical human behavior. The Revised Children's Anxiety and Depression Scale (RCADS) was used to assess anxiety in 126 high-functioning 9-13 year-olds with ASDs. Network graphs of Autism Diagnostic Observation Schedule items and RCADS anxiety total score, social, generalized, panic and separation anxiety subscores consistently found the anxiety node (score) to be highly peripheral. Also, the networks of RCADS anxiety items themselves were similar for the ASDs group and a general population comparison group (n = 2017). The results suggest anxiety is not a central part of autism and that anxiety is dynamically similar (aspects of anxiety relate to one another in a similar manner) in high-functioning autism and the general population.
