Specifications include, but are not limited to: PHASE I - Document Review and Planning Task 1. Conduct a review and synthesis of existing studies related to teen and young driver social norms, attitudes, knowledge, and perceptions related to cannabis and driving. This task should primarily focus on domestic research, with relevant international information to be considered. Task 2. Document noteworthy domestic and relevant international educational resources and interventions that (1) support parents of teens/young drivers, SHSOs, high schools, universities, employers, cannabis dispensaries, and others in talking with teens and young drivers about cannabis impaired driving and impaired driving laws; and (2) provide information about cannabis impaired driving and impaired driving laws directly to teens and young drivers. Task 3. Develop an outline for the educational resources and interventions to be developed under Task 8. Task 4. Develop a data collection and analysis plan for conducting new research in Phase II to accomplish the project's objectives. This will include at a minimum: 1. Analysis to identify social norms, attitudes, knowledge, and perceptions of teens and young drivers related to cannabis and driving. 2. Development of evidence-based approaches and models to support (a) use by parents of teens/young drivers, SHSOs, high schools, universities, employers, cannabis dispensaries, and others in talking with teens and young drivers about cannabis impaired driving and impaired driving laws and (b) direct use by teens and young drivers. Task 5. Prepare Interim Report #1 that documents the work completed in Tasks 1 through 4. Update the work proposed for Phase II. Note: Following a 1-month review of Interim Report #1 by the BTSCRP, the research team will be required to meet in-person with the BTSCRP project panel in Washington, D.C. to discuss Interim Report #1. Costs for the in-person meeting venue and travel costs for BTSCRP panel members will be paid separately by BTSCRP. Work on Phase II will not begin until authorized by the BTSCRP. PHASE II - Data Collection and Analysis Task 6. Execute the plan in Interim Report #1 to achieve the research objectives. Task 7. Prepare Interim Report #2 that documents the work completed in Task 6. Update the work proposed for Phase III. Note: Following a 1-month review of Interim Report #2 by the BTSCRP, the research team will be required to meet remotely with the BTSCRP project panel. Work on Phase lII will not begin until authorized by the BTSCRP. PHASE III - Deliverables Task 8. Develop educational resources and interventions to support (1) parents of teens/young drivers, SHSOs, high schools, universities, employers, cannabis dispensaries, and others in talking with teens and young drivers about cannabis impaired driving and impaired driving laws; and (2) awareness by teens and young drivers about issues related to cannabis impaired driving and impaired driving laws. The materials should be customizable by the intended audience in order to be applied in a range of regional and cultural settings. Task 9. Conduct a workshop with at least 15 representatives of SHSOs, law enforcement agencies, teens/young drivers, and other key stakeholders to present key research findings and proposed educational resources. Revise the educational resources and workshop materials taking into account feedback gathered during the workshop.
