Researcher--community partnerships are a necessary but not sufficient facet of effective research and evaluation with community-based projects and in clinical settings. This article describes two approaches that we have integrated into a multiyear, multiphase research and evaluation initiative supporting the health and well-being of vulnerable families. Specifically, we adopted a relational approach, intentionally and consistently focusing on building relationships, and a trauma-informed approach, highlighting safety across all levels. These innovative approaches have facilitated success in conducting safe, meaningful research and evaluation with community partners. Based on these approaches, we outline specific strategies and key considerations used in the context of the initiative, with the goal of encouraging others to adopt relational and trauma-informed methodological approaches and use these frameworks in research and evaluation efforts in applied settings.
