Toward Integration of Life Course Intervention and Youth Participatory Action Research.

We provide an overview of diverse forms of youth participation, with a focus on youth participatory action research (YPAR) and its synergies with life course intervention research to promote healthier development for young people and across the life span. We analyze why YPAR matters for research, practice, and policies related to the systems and settings in which young people develop. We also illustrate how young people perform YPAR work to improve the developmental responsiveness and equity of school and health systems, including descriptions of an innovative youth-led health center in Rwanda and a long-standing and evolving integration of YPAR into public high schools in the United States. We then briefly consider the adult capacities needed to do this work well, given that YPAR challenges typical youth-adult power relationships and broader assumptions about who can generate expert knowledge. We consider the alignment and potential challenges for integration of life course intervention research as well as YPAR and next steps for research and practice at this intersection.
