Improving the Part C Early Intervention Service Delivery System for Children With ASD

Despite strong consensus that early, specialized intervention for children with autism spectrum disorder (ASD) can have a dramatic impact on outcomes, the public health system's capacity to provide such services is severely challenged by the rapid rise in ASD prevalence. The goal of this research project is to increase timely and equitable access to ASD-specialized early intervention during the critical first three years of life by capitalizing on the existing infrastructure of the Part C Early Intervention (EI) system, which is publicly funded and available in all states in the United States. This project will train EI providers to use an evidence-based, parent-mediated intervention that can improve child and family outcomes as well as mitigate the long-term substantial economic costs associated with ASD.

The long-term goal of this study is to improve services and outcomes for children with early social communication challenges and/or ASD by increasing the capacity to provide appropriately specialized treatment within an existing infrastructure: the Part C Early Intervention (EI) service delivery system. Part C is publicly funded, available throughout the United States, and serves children under age 3 who have developmental delays or disabilities. Currently, the effectiveness of EI services is limited by high practice variation and infrequent use of evidence-based interventions. We are conducting a randomized controlled trial (RCT) to examine the effectiveness of training EI providers to deliver Caregiver-Implemented Reciprocal Imitation Teaching (CI-RIT) to children showing early social communication challenges. RIT is a naturalistic developmental behavioral intervention (NDBI) that is ideally suited for EI settings because it is low intensity, play-based, easy to learn and implement, and can be taught to families for their independent use (in the form of CI-RIT), thus increasing intervention dosage. This RCT will employ a hybrid type 1 effectiveness/ implementation design and will use a unique mixed methods approach to gather evidence that will be essential for implementing RIT at scale, pending positive trial results. The sample includes a target of 20 EI agencies (across 4 U.S. States), 160 EI providers and 440 families of children with early social communication challenges, which not only provides a robust sample size, but also affords the opportunity to assess the generalizability of this approach across regions that vary in their implementation of Part C services. EI providers will be randomly assigned to the RIT training group (n=80) or treatment as usual (TAU; n=80). Providers in both groups will identify 2-5 children in their caseload who are 16-33 months old with early social communication delays (target n=220 children per group). Intensive, state-of-the art, multimethod assessment technology will be used to measure the impact of the intervention. Child and family assessments will be conducted at baseline, 4 months after enrollment, and 9 months after enrollment. Importantly, this study will examine putative mechanisms through which RIT improves clinically-relevant outcomes. In sum, this study will generate the evidence necessary to implement RIT at scale, thereby increasing the capacity of the existing EI system to deliver effective, evidence-based intervention to the rapidly growing population of children who show early social communication challenges. The objectives of the RISE study are as follows: 1. To test the effectiveness of CI-RIT as delivered by community-based EI providers for improving child- and caregiver/family-level outcomes. We hypothesize that compared to TAU, children working with CI-RIT providers will demonstrate greater improvements in motor imitation and joint attention at T2 (4-months post-baseline), and langua Покажи пълното описание...
