All trials for Autism Spectrum Disorder All trials of Reciprocal Imitation Training
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 language and social communication at T3 (9-months post-baseline). We also hypothesize that compared to TAU, caregivers working with CI-RIT providers will show greater improvements in contingent responsivity, RIT strategy use, parenting efficacy, and family quality of life.
2. To analyze the mechanisms by which CI-RIT improves outcomes. We hypothesize that changes in children's social communication and language outcomes will be serially mediated by gains in: (a) caregiver contingent responsivity and caregiver RIT strategy use, and (b) children's motor imitation and joint attention. We hypothesize that changes in caregiver/family outcomes will be mediated by gains in caregiver contingent responsivity, caregiver RIT strategy use, child motor imitation, and child joint attention.
3. To prepare for implementation at scale by identifying potential sources of practice variation to inform refinement of RIT training and development of quality assurance protocols. Triangulating evidence from video observations of EI sessions, EI provider self-reports, and qualitative interviews, we will use the Model for Adaptation Design (MADI) framework (32) to characterize the modifications to RIT that providers make (MADI domain 1), to identify potential mediating or moderating factors of these modifications (e.g., relationship to fidelity, rationale) (MADI domain 2), and to explore whether all or certain modifications influence implementation outcomes (e.g., ongoing fidelity, treatment acceptability) (MADI domain 3). This robust implementation evaluation will provide relevant information for improving the delivery of all NDBIs in the Part C system.
| Arm | Type | Interventions | Description |
|---|---|---|---|
| RIT Training Group | Experimental | Behavioral: Reciprocal Imitation Training | Providers in the RIT group (n=80) will receive intensive training (online tutorial, 2-day workshop, and virtual coaching and feedback in the field) in RIT and parent coaching and will be required to achieve fidelity prior to enrolling families from their caseload. They will then be asked to use the intervention with enrolled families for a minimum of 3 months. One intervention session per month for each enrolled family will be videotaped and scored for fidelity. Providers will receive monthly consultation from RIT trainers while these families are in the active treatment phase. |
| Treatment as Usual | No intervention | Providers in the TAU group (n=80) will have three sessions videotaped and scored for each enrolled family to assess treatment differentiation. To incentivize agency participation, RIT training will be provided to the TAU group and other providers when data collection is complete. |
Sex: All, ages: 16 Months to 33 Months
