Comparative Efficacy of Family-Mediated Intervention Versus Early Intensive Behavioral Intervention on Developmental Domains in Children with Autism Spectrum Disorder: A Randomized Controlled Trial

Background: Autism spectrum disorder is a neurodevelopmental disorder of childhood in which there is a deficit in social and communicative skill, and the child shows restricted and repetitive behavior. For children diagnosed with autism spectrum disorder, family-mediated intervention and early intensive behavioral intervention are considered standard of care. The study aimed to compare their efficacy on social skills and other developmental domains in our cultural context.Methods: This study was a parallel-arm, open-label, randomized active-controlled clinical trial. Fifty children diagnosed with autism spectrum disorder were randomly assigned to either the family-mediated intervention or early intensive behavioral intervention groups. Communication DEALL Developmental Checklist was applied at 0, 12, and 24 weeks.Results: The difference in the mean value of Communication DEALL Developmental Checklist at the end of 24 weeks from the initial value was significantly better in the family-mediated intervention as compared to the early intensive behavioral intervention group in social (mean difference = -16.8, 95% CI = -27.18, -6.49, p = .002) as well as fine motor, cognitive, and overall development. In other developmental domains of Communication DEALL Developmental Checklist, the family-mediated intervention group performed better in comparison to the early intensive behavioral intervention group at different time periods although not statistically significant.Conclusion: The results of the study indicated that, throughout the course of 24 weeks of treatment, autism spectrum disorder children in family-mediated intervention showed a distinct improvement in major developmental domains. Family-mediated intervention can be advocated for autism spectrum disorder children in our cultural context in view of improved functioning in major developmental domains in the background of our study findings.
