This paper explores the application of ethic of care principles to research practice. It reflects on a research partnership between a voluntary-sector organisation (VSO) for older people and a university research centre (URC). The focus is a participatory research project on older people and well-being in which older volunteers were involved as co-researchers. The shared values of the VSO's culture of practice and the participatory approach of the university researchers have enabled joint research projects to be developed within an ethic (...) of care framework. The model sought to break down the barriers between expert and lay knowledge and encouraged the mutual recognition, sharing and validating of different areas of expertise. An ethic of care framework offers context-specific ways of understanding and responding to the ethical challenges of undertaking participatory research, and to the relational aspects of well-being identified by older people during the course of the work.
