The Talking Dads Project brought together young fathers, an NGO and university researchers to explore the experiences of young fathers in a UK seaside city. Young fathers took a lead role in developing the content of, and conducting, interviews with peer participants. Drawing on an analytical framework derived from participatory research literature, this paper provides an analysis of five critical processes that created intense debate and became sites for negotiation of the delicate balance of powers between participants. These included young fathers' initial engagement, the translation of their research ideas into research tools, research ethics such as confidentiality and duty of care, the academic researchers' role in making adjustments to facilitate comprehensive, in-depth data-collection, and the differential impact of the research on the lives of all involved. The learning emerging from this evaluation of the research process contributes to understanding of the challenges of participatory research and the value of flexibility in responding to challenges and constraints
