Mind the Gap will include 20 agency staff, 48 Peer Navigators working at participating community organizations with peer navigator capacity (e.g. parent support centers; FQHC; community clinics; faith-based agencies) serving children with ASD and other NDD; and 240 families of children age 2-8 (with potential expansion based on community feedback) with ASD or NDD.

Training will be provided by experts in each intervention at each CRE. MTG targets peer navigators (parents of children with disabilities) who will complete the 12- hour remote training on MTG modules and associated topics (e.g., boundaries, family and child safety, data collection). The research team will conduct the initial 12 hours of training and active coaching/check ins during the 12 sessions the peer navigator has with the family in a 6-month span. Agency staff (supervisors or managers of agencies) will be also be given the training to help facilitate the training of the peer navigators at their respective sites and participate in UNITED if randomized to receive it. Identified families connected to the community organization will be matched with one peer navigator who will then guide and support the caregiver through completion of the MTG modules with active coaching of the family. Family needs and preferences will guide topic selection. Active coaching will occur via zoom, or over the phone, based on family preference.Consents can be signed online via Qualtrics, DocuSign (UC Davis) or RedCap for the parents, peer navigators, and agency staff. The parents participating in Mind the Gap will fill out a Demographic, Family Empowerment Scale, Permission to Contact, and WHO QOL Scale at entry. They will also fill out the following surveys at exit (6 months): Family Empowerment Scale and Caregiver Satisfaction Survey. Mind the Gap will be available in English, Spanish, and Korean. Peer navigators will fill out the following surveys at entry after signing consent: demographic, implementation climate scale, and social network surveys. They will also fill out surveys at 12 months and 18 months, which consist of social network surveys, implementation climate scale and an exit survey (only at 12 months).

All participants in Mind the Gap will be randomized to receive UNITED, exploratory implementation strategy, or implementation as usual (IAU). UNITED is premised on the idea that successful implementation in organizations like schools and early intervention systems requires a team-based approach, in which the team is thoughtfully assembled, develops a plan for implementation, assigns roles and responsibilities, and carefully tracks and supports implementation and sustainment in all its stages. To address these requirements, we combine two well- tested strategies. The first is social network analysis (SNA) through which we will systematically identify members of the team who will implement each intervention. The second is TeamSTEPPS (Team Strategies and Tools to Enhance Performance and Patient Safety), an evidence-based set of teamwork tools that optimizes target population outcomes by improving communication and teamwork skills. The research staff will approach the site leaders (2 at maximum) at agencies and explain MTG. After the site leaders agree to participate in the study, they will complete an agency agreement to participate and then fill out the Social Network Assessment (SNA) to provide names, roles, and emails of staff at the agency that have significant roles in the agency that relate to the Mind the Gap intervention. The research staff will then email these agency staff the SNA as well. After receiving the completed SNA assessments, we will randomize each organization to UNITED vs Implementation as Usual (IAU). We will use the data from these assessments to assess both arms of the study. Additionally, for those randomized to UNITED, Dr. Elizabeth McGhee Hassrick at Drexel University and her team, will provide the research sites the top 2-5 agency staff identified by the SNA as key for intervention implementation support. This team will be invited to participate in the UNITED implementation team. If they agree, they will complete an Agency Rep Consent before beginning any UNITED training. For both UNITED and IAU sites, peer navigators will be recruited from the agency based on leader recommendations. They will complete the Peer Navigator Consent prior to beginning Mind the Gap training.
