Adapted cognitive behavior therapy for obsessive-compulsive disorder with co-occurring autism spectrum disorder: A clinical effectiveness study.
Adapted CBT plus ERP cuts OCD severity in autistic adults, yet most still have symptoms and daily skills stay flat.
01Research in Context
What this study did
Oskar and his team gave 21 autistic adults a version of CBT made for OCD. The therapy added extra structure, visual aids, and caregiver help. Each person got 16 weekly sessions plus home practice.
Clinicians rated OCD severity before, after, and three months later. No control group was used.
What they found
OCD scores dropped a lot right after therapy and stayed lower three months later. Only 4 out of 21 people reached full remission. Daily-life skills did not improve.
How this fits with other research
Cox et al. (2015) saw a similar story in autistic youth: big anxiety drops, but some symptoms crept back. Their follow-up lasted a year, while Oskar stopped at three months.
Lord et al. (2005) warned that most autism psychosocial studies lack control groups. Oskar’s work answers that call with a clear pre-post design, yet still skips a control.
Murphy et al. (2007) also ran small adult CBT case series. Both papers show gains, but behavior change stays uneven, hinting that CBT alone may not fix real-life problems.
Why it matters
You can expect big OCD score drops when you add ERP to CBT for autistic adults, but plan for booster sessions—only one in six hit remission. Track daily-life goals separately, because symptom relief does not guarantee functional gains.

03Original abstract
Obsessive-compulsive disorder and autism spectrum disorder commonly co-occur. Adapted cognitive behavior therapy for obsessive-compulsive disorder in adults with autism spectrum disorder has not previously been evaluated outside the United Kingdom. In this study, 19 adults with obsessive-compulsive disorder and autism spectrum disorder were treated using an adapted cognitive behavior therapy protocol that consisted of 20 sessions focused on exposure with response prevention. The primary outcome was the clinician-rated Yale-Brown Obsessive-Compulsive Scale. Participants were assessed up to 3 months after treatment. There were significant reductions on the Yale-Brown Obsessive-Compulsive Scale at post-treatment (d = 1.5), and improvements were sustained at follow-up (d = 1.2). Self-rated obsessive-compulsive disorder and depressive symptoms showed statistically significant reductions. Improvements in general functioning and quality of life were statistically non-significant. Three participants (16%) were responders at post-treatment and four (21%) were in remission from obsessive-compulsive disorder. At follow-up, three participants (16%) were responders and one (5%) was in full remission. Adapted cognitive behavior therapy for obsessive-compulsive disorder in adults with co-occurring autism spectrum disorder is associated with reductions in obsessive-compulsive symptoms and depressive symptoms. However, outcomes are modest; few patients were completely symptom free, and treatment engagement was low with few completed exposures and low adherence to homework assignments. We identify and discuss the need for further treatment refinement for this vulnerable group.
