Anxiety in Autistic Children and Teens
A large NIMH-funded meta-analysis found that around 40% of autistic children and teens meet criteria for at least one anxiety disorder — several times the rate in the general population. Separation anxiety, specific phobias, social anxiety, OCD, and generalized anxiety are all more common.
Why it often gets missed
Anxiety in autistic kids often doesn't look like classic worry-talk. It can look like:
- Increased rigidity or ritual
- More stimming
- Meltdowns triggered by "small" things
- Refusal (school, food, activities)
- Somatic complaints (stomach aches, headaches)
- Sleep regression
Because these overlap with autism itself, clinicians can attribute everything to autism and miss treatable anxiety.
What treatment works
- Modified CBT. Standard CBT works for many autistic kids when adapted — more visuals, concrete examples, longer duration, parent involvement. The Facing Your Fears program (developed at the University of Colorado) is designed specifically for autistic children and has RCT support.
- Exposure hierarchies built with the child, not for them.
- SSRIs may help when anxiety is severe or CBT is not enough. AAP guidance is to combine medication with therapy rather than use meds alone.
What families can do at home
- Name the feeling (many autistic kids under-detect internal states — a feelings thermometer helps).
- Reduce demands during high-anxiety periods; don't remove them entirely (avoidance grows the fear).
- Predictability wherever possible: visual schedules, advance warnings, "what happens next" scripts.
- Sleep, food, and movement first. Anxiety is much harder to treat on top of unmet basics.
When to get help
Anxiety that stops the child from school, sleep, eating, or leaving the house warrants a mental-health evaluation. Ask specifically for a clinician experienced with autism.
