RESUMEN
While the principles behind community-based participatory research are firmly established, the process of taking community-based participatory research with children and youth to scale and integrating it into the programming of non-governmental organizations has been scarcely documented. This article reflects on the experiences of Save the Children in implementing a multicountry community-based participatory research program to increase understanding of kinship care in the Democratic Republic of Congo, Nigeria, and Sierra Leone. The article discusses challenges faced and lessons learned and highlights how the research process enabled action and advocacy initiatives at different levels-leading to an increase in support and policy attention for children living in kinship care.
