We aim to advance Indigenous evidence-based practice and policy for the benefit of Indigenous birthing families and young children by carrying out research to decrease the gap between innovative Indigenous-led programming, data production, and dissemination efforts. As we build our internal community-driven research capacity to document the impacts of its programs on birth justice in western Washington state, this grant is focused on further developing our research and evaluation efforts across Hummingbird’s direct service programs, enhancing our data-driven policy advocacy capabilities, and positioning Hummingbird to contribute to a broader national landscape of Indigenous community-led science. This project looks at how existing program data, rigorous community engagement, and Indigenous research frameworks can be used to develop a systems impact-focused evaluation plan for Hummingbird’s core service programs to assess the effects these programs are having on Indigenous health and birth justice outcomes at the individual, community, and regional/policy levels.
