Family-Centric Applied Behavior Analysis Facilitates Improved Treatment Utilization and Outcomes.

Area of Science:

• Neurodevelopmental Disorders
• Behavioral Science
• Pediatric Health

Background:

• Autism spectrum disorder (ASD) presents lifelong challenges in social skills, daily living, and includes restricted, repetitive behaviors (RRBs).
• Applied Behavior Analysis (ABA) is the gold-standard treatment for ASD, but access is limited by professional availability and cost.
• Parent-led ABA models can overcome these barriers, improving treatment accessibility.

Purpose of the Study:

• To examine the impact of a parent behavior technician (pBT)-delivered ABA model on adaptive and interfering behaviors (IBs) in children with ASD.
• To assess the effectiveness of this model across varying ASD severity levels and the presence of clinically significant IBs.

Main Methods:

• A retrospective cohort study involving 36 patients aged 3-15 years.
• Longitudinal assessment of clinical outcomes using Vineland-3 scores after 3+ months of pBT-delivered ABA treatment.

Main Results:

• Patients showed clinically significant improvements in Vineland-3 Composite, domain, and subdomain scores.
• Treatment utilization was higher in children with severe ASD.
• Children with clinically significant IBs at baseline demonstrated greater gains in Composite scores.

Conclusions:

• The pBT model demonstrated high treatment utilization and robust effectiveness in improving adaptive behaviors and reducing IBs compared to conventional ABA.
• This parent-led ABA approach is a viable solution to address the treatment accessibility gap in ASD.
• The pBT model offers a powerful tool to overcome systemic issues in ABA treatment delivery.
