Efficacy Study of a Social Communication and Self-Regulation Intervention for School-Age Children With Autism Spectrum Disorder: A Randomized Controlled Trial

Abstract

Purpose This study aimed to examine the initial efficacy of a parent-assisted blended intervention combining components of Structured TEACCHing and Social Thinking, designed to increase social communication and self-regulation concept knowledge in 1st and 2nd graders ( n = 17) diagnosed with autism spectrum disorder (ASD) and their parents. Method A randomized delayed treatment control group design with pre- and postintervention assessments of both parents and children was implemented within a community practice setting. Two follow-up assessments at 3 and 6 months postintervention were also completed. Results Overall, results indicate that the intervention is efficacious in teaching social communication and self-regulation concept knowledge to children with ASD and their parents. Both parents and children demonstrated an increase in social communication and self-regulation knowledge after participating in the Growing, Learning, and Living With Autism Group as compared to a delayed treatment control group. The effects of the intervention did not extend to parent-child interactions coded from video recordings. Child treatment effects were maintained at the 3- and 6-month follow-up assessments. Conclusions Preliminary efficacy of the Growing, Learning, and Living With Autism Group was established. Based on parent report at the conclusion of the intervention, this is a socially valid intervention for teaching social communication and self-regulation skills to school-age children with ASD.
