A Comparative Trial of Occupational Therapy Using Ayres Sensory Integration and Applied Behavior Analysis...

Area of Science:

• Pediatric occupational therapy
• Autism spectrum disorder interventions
• Sensory integration therapy

Background:

• Autistic children often exhibit sensory integration differences affecting daily activities.
• Occupational Therapy using Ayres Sensory Integration (OT-ASI) and Applied Behavior Analysis (ABA) are evidence-based autism interventions.

Purpose of the Study:

• To compare the effectiveness of OT-ASI, ABA, and no treatment for autistic children with sensory differences.
• To evaluate impacts on daily living skills and individualized goals.

Main Methods:

• A parallel arm comparative effectiveness trial.
• Participants were randomized to OT-ASI, ABA, or no treatment groups.
• Intervention involved 30 one-hour sessions.

Main Results:

• Both OT-ASI and ABA groups showed significant gains in individualized goals (Goal Attainment Scaling) compared to the no treatment group.
• Improvements in daily living skills (Pediatric Evaluation of Disabilities Inventory) were observed in both treatment groups but were not statistically significant over no treatment.
• OT-ASI and ABA demonstrated comparable effectiveness in improving individualized goals and daily living skills.

Conclusions:

• Both OT-ASI and ABA are effective interventions for improving outcomes in autistic children with sensory differences.
• The findings support the use of OT-ASI and ABA as comparable therapeutic approaches for this population.
• Implications for clinical practice and intervention strategies are discussed.
