Using community engagement with

Community engagement is increasingly considered a key component of intervention development, as it can leverage community members' knowledge, experiences, and insights to create a nuanced intervention which meets the needs, preferences, and realities of the population of interest. Community engagement exists along a spectrum from outreach to the community to partnership with community members and organizations, and all levels of community engagement can benefit from systematic documentation of community feedback and decision-making processes. This paper demonstrates how we utilized the "Framework for Reporting Adaptations and Modifications to Evidence-based Interventions" (FRAME; Wiltsey Stirman et al., 2019) model to track and report adaptations to our dementia end-of-life care planning intervention based on community engagement via a project-specific Community Advisory Board (CAB). Using FRAME, we generated a comprehensive report of the iterative changes made to our pilot intervention, including whether the change was planned, who made the decision to modify the intervention, the nature of the change, its relationship to intervention fidelity, and the reason for the change. This process ensured that we effectively integrated feedback and assistance from our CAB, increased the appropriateness of our intervention for our population of interest, established criteria to monitor intervention fidelity, and prepared our team to run a rigorous clinical trial of the revised intervention.
