SDLMI targets school-based providers across grade levels (i.e., 6th - 12th grade) and disciplines (e.g., special education, general education). They will receive 7.5 hours of remote professional development in SDLMI. Coaching will take placed based on the SDLMI Facilitator Objectives that provide a road map for the facilitator. In school contexts, SDLMI instruction is implemented over the course of a school year or 2 semesters (approximately 24 weeks). Practitioners will receive 12 hours of remote coaching during sessions with students.

There will be 3 assessment time points. At entry, the teachers/school staff will fill out Demographic, Implementation Climate, Knowledge, Skills, and Use, and Acceptability of Intervention Measure (AIM). At 12 weeks of the study and at 24 weeks of the study (exit), they will fill out Implementation Climate, Knowledge, Skills, and Use, and Acceptability of Intervention Measure (AIM). Teachers/school staff will also fill out SDLMI fidelity questionnaire 6 times over the course of the school year. The parents will fill out a Demographic form at entry. Students will complete the following questionnaires at entry, mid-study (12 weeks) and end of study (24 weeks): the Self Determination Inventory: Student Report and Goal Attainment Scaling as a part of the SDLMI intervention.

All participants in SDLMI 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, the research team combined two well-tested strategies. The first is social network analysis (SNA) through which the research team 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 school leaders (2 at maximum) and explain SDLMI. After the school leaders agree to participate in the study, they will complete a site agreement to participate and then fill out the Social Network Assessment (SNA) to provide names, roles, and emails of school personnel at the school that have significant roles in the school that relate to SDLMI. The research staff will then email these school personnel the SNA as well. After receiving the completed SNA assessments, the research staff will randomize each organization to UNITED vs Implementation as Usual (IAU). The research team 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 school personnel identified by the SNA as key for intervention implementation support. This team will be invited to participate in the UNITED implementation team.
