This article reflects on six years of work that implemented various participatory research methods with young women linked to gangs in El Salvador. The reflection focuses on the fundamental role of emotions and trust in contexts marked by violence and social exclusion. From the Freirean perspective of popular education and the approaches of Haraway and Butler, it also analyzes how these participatory methodologies with an autobiographical focus contribute to the re-signification of identities, the construction of agency, and the creation of safe spaces for dialogue. Through methods such as the systematization of experiences, life narratives, and critical ethnography, not only was the complexity of the participants’ lived realities captured, but the investigative process also became a vehicle for empowerment and social transformation. This article highlights how the ethical management of emotions, combined with the construction of trust-based relationships and the use of an autobiographical approach in participatory methodologies, redefines research as a humanized and transformative practice in the study of stigmatized and excluded populations. The findings emphasize the recognition of the contribution participatory research makes in contexts of violence and exclusion for the design of public policies, programs, or reintegration strategies. This underscores the need to promote research lines and funding that advance such proposals from the social sciences, establishing them as key tools for structural transformation.
