Abstract Participatory methods contribute to scientific rigor by highlighting the contextual needs, especially of underrepresented populations, making them protagonists in the process of social change. This article aims to present the application of a participatory research method, called Community-Based Participatory Research (CBPR), in a context of social vulnerability in southern Brazil. It seeks to discuss the challenges and strengths of the method, which provides ecological validity for the development of public policies appropriate to the context, while empowering the participants. The research has been carried out since 2019 and, among the inherent challenges, has also faced the difficulties posed by the COVID-19 pandemic. Based on the application of this method in Brazil, the importance of involving participants throughout the research process has been identified, so that policies are developed to meet the needs of the community and are sustained by those most interested.
