Effects of Cognitive Behavioral Therapy for Reducing Anxiety in Children with High Functioning ASD: A Systematic Review and Meta-Analysis.

Celal and colleagues looked at 23 studies that tested CBT for anxiety in children with high-functioning autism. They pooled the numbers to see how well the therapy works. All studies used standard CBT packages, mostly in clinics or schools.

CBT cut anxiety by a moderate amount across the 23 studies. The benefit grew when parents joined the sessions and when treatment lasted longer. Kids who got CBT had noticeably lower worry, avoidance, and physical signs of stress.

Vause et al. (2020) got even larger drops in obsessive rituals with a CBT plan that starts with a functional behavior assessment. Their single study beat the average effect Celal found for general anxiety.

Byiers et al. (2025) built on Celal’s tip about parent power. They let caregivers pick the top three anxiety problems to target. Caregiver-chosen goals improved faster than in standard CBT.

Pickard et al. (2019) warn that most of the 23 studies Celal pooled were mostly White, higher-income families. The meta-analysis result may not match the diverse kids you see in practice.

Taylor et al. (2017) show CBT can also help children with autism plus intellectual disability when it is blended with behavior support. Celal’s review left these kids out, so the meta result applies only to verbal, higher-IQ learners.

You can now tell funders and parents that CBT has a solid evidence base for anxious, verbal learners with ASD. Add a parent module and run at least 12–16 weeks to reach the effect seen in the meta-analysis. Start with a brief functional assessment if rituals are part of the picture; the Tricia study shows this can boost impact.
