This study examined the feasibility of implementing the Screening Tool for Autism in Toddlers, an interactive Level-2 screen for autism spectrum disorder, within Part C Early Intervention settings. Participants included 69 Early Intervention providers ( M age = 43.3 years, 93.7% females, 92.4% Whites) from nine programs who attended a one-day Screening Tool for Autism in Toddlers training workshop. Half of the providers reported using the Screening Tool for Autism in Toddlers, and reported it to be feasible and effective. Regardless of Screening Tool for Autism in Toddlers use, providers reported increased knowledge about recognizing the early signs of autism spectrum disorder following the workshop. Provider-reported self-efficacy regarding skills related to autism spectrum disorder screening increased significantly from baseline to the 18-month follow-up. Providers also described the facilitators (e.g. promotes communication with families) and barriers (e.g. certification process), that influenced their adoption. Results highlight the potential use of the Screening Tool for Autism in Toddlers within Early Intervention settings to identify autism spectrum disorder, and suggest an implementation model in which specific providers serve as a screening “point-person,” rather than expecting it to be used by all providers. Future research should aim to identify characteristics of agencies or providers that might facilitate Screening Tool for Autism in Toddlers use, as well as specific implementation plans and strategies that might promote long-term sustainability of Level-2 screening practices.

Lay abstract

The early detection of autism spectrum disorder can lead to access to autism spectrum disorder-specific services that have been shown to have a large impact on a child’s overall development. Although a stable diagnosis of autism spectrum disorder can be made by age 2 years, most children are not diagnosed until much later. To address this issue, this study examined the effectiveness of training Part C Early Intervention providers to use an interactive autism spectrum disorder screening tool, the Screening Tool for Autism in Toddlers. Sixty-nine providers attended a 1-day training workshop on the use of the Screening Tool for Autism in Toddlers. After the workshop, providers reported increased knowledge about recognizing the early signs of autism spectrum disorder, and about 45% of the providers reported using the Screening Tool for Autism in Toddlers with families in their caseloads 18 months after the training. These results suggest that the Screening Tool for Autism in Toddlers is feasible for use within Early Intervention settings. In addition, they suggest that specific providers might serve as a screening “point-person,” rather than expecting the Screening Tool for Autism in Toddlers to be used by all providers. Future research should aim to identify specific characteristics of agencies or providers that might be best suited for using the Screening Tool for Autism in Toddlers.
