Evidence-based practices (EBPs) have been shown to improve outcomes for children diagnosed with autism spectrum disorder (ASD; Wong et al., 2015). Research suggests that the utilization of these practices in community settings is varied (Paynter & Keen, 2015; Pickard, Meza, Drahota, & Brikho, 2018); however, the utilization of implementation guides may bridge the gap between research and practice (Drahota et al., 2017).

Research suggests that the utilization of these practices in community settings is varied (Paynter & Keen, 2015; Pickard, Meza, Drahota, & Brikho, 2018); however, the utilization of implementation guides may bridge the gap between research and practice (Drahota et al., 2017). The Autism Community Toolkit: Systems to Measure and Adopt Research-Based Treatments (ACT SMART Toolkit; Drahota, Meza, & Martinez, 2014) is a web-based implementation toolkit developed to guide ASD implementation teams through the phases of EBP implementation in community agencies. This study examined the barriers and facilitators (collectively termed "determinants") to the utilization of this toolkit, based on the perspectives of implementation teams at six ASD community agencies. Two independent coders utilized the adapted EPIS model (Drahota et al., 2017; Moulin et al., 2019) and the Technology Acceptance Model 3 (Venkatesh & Bala, 2008), to guide thematic analyses of participant interviews. Salient determinants were identified, and analyses highlighted two themes: (a) Inner Context Determinants to use of the toolkit (e.g., funding), and (b) Innovation Determinants (e.g., facilitation teams). Finally, determinants that differed across adapted EPIS phases of the toolkit were identified. Findings highlight areas of improvement for the ACT SMART Implementation Toolkit, as well as factors to facilitate the use of this implementation guide. Additionally, findings may inform the development, refinement, and utilization of implementation guides with the aim of increasing the uptake of evidence-based practices in community agencies providing services to children with autism spectrum disorder.
