Functional Behavior-Based Cognitive-Behavioral Therapy for Obsessive Compulsive Behavior in Children with Autism...

Area of Science:

• Clinical Psychology
• Developmental Psychology
• Neurodevelopmental Disorders

Background:

• Children with autism spectrum disorder (ASD) often exhibit obsessive-compulsive behaviors (OCBs).
• Limited controlled research exists on effective treatments for OCBs in youth with ASD.

Purpose of the Study:

• To evaluate the efficacy of functional behavior-based cognitive behavior therapy (Fb-CBT) for OCBs in children with high-functioning ASD.
• To compare Fb-CBT with Treatment As Usual (TAU) in reducing OCBs and improving quality of life.

Main Methods:

• A randomized controlled trial (RCT) involving 37 children (7-13 years) with high-functioning ASD (IQ ≥ 70).
• Participants were randomly assigned to a 9-week Fb-CBT intervention or TAU.
• Independent assessors collected data pre-treatment, post-treatment, and at 6-month follow-up.

Main Results:

• Statistically significant differences were observed between the Fb-CBT and TAU groups on two primary outcome measures.
• Large corrected effect sizes (Hedge's g = 1.00 and 1.15) indicated substantial treatment effects.
• Fb-CBT demonstrated a promising reduction in obsessive-compulsive behaviors.

Conclusions:

• This is the first RCT exclusively targeting OCBs in children and youth with high-functioning ASD.
• Fb-CBT shows significant promise in decreasing obsessive-compulsive behaviors in this population.
• The findings suggest that Fb-CBT can improve the quality of life for children with ASD experiencing OCBs.
