Comparative effectiveness trial: Modular behavior approach for young autistic children compared to comprehensive...

Area of Science:

• Developmental Psychology
• Clinical Psychology
• Pediatric Medicine

Background:

• Early intervention is critical for autistic children.
• Comprehensive Behavioral Intervention (CBI) is a common treatment, often requiring significant time commitment.
• There is a need for flexible, potentially lower-intensity interventions tailored to individual needs.

Purpose of the Study:

• To compare a novel modular approach for young autistic children (MAYAC) with standard Comprehensive Behavioral Intervention (CBI, TAU).
• To assess the efficacy and parent satisfaction of MAYAC.
• To determine if MAYAC is non-inferior to CBI, TAU in improving adaptive behaviors.

Main Methods:

• A 24-week single-blind trial involving 56 autistic children (18-60 months).
• Intervention groups: MAYAC (5-10 hours/week, modular, parent input) and CBI, TAU (≥15 hours/week).
• Outcome measures included Vineland Adaptive Behavior Scales (VABS), Ohio Autism Clinical Improvement Scale - Autism Severity (OACIS-AS), and Pervasive Developmental Disorder Behavior Inventory - Parent (PDDBI-P).

Main Results:

• Both MAYAC and CBI, TAU groups showed significant improvements on the VABS from baseline.
• MAYAC was found to be non-inferior to CBI, TAU on the VABS (p=0.0144).
• Similar treatment response rates were observed on the OACIS-AS; no significant changes were noted on the PDDBI-P for either group. High treatment fidelity and parent satisfaction were reported for both.

Conclusions:

• The modular approach for young autistic children (MAYAC) is a viable alternative to standard Comprehensive Behavioral Intervention (CBI, TAU).
• MAYAC demonstrates comparable effectiveness to CBI, TAU in improving adaptive behaviors for young autistic children.
• The findings suggest MAYAC's potential as a flexible and effective early intervention option.
