Experiences and factors affecting participationWith the exception of participation as research subjects or patients, members of the public's participation in research decision-making has for many years been marked by their exclusion. Scientifically produced knowledge was seen as the sole reliable source of robust knowledge, and producers and holders of this knowledge were amongst the few seen as capable of making decisions or setting policies associated with research production ( Community-based research (CBR) is an approach to research which makes use of the knowledge of members of the public, also referred to as community members. Public participation in CBR means that members of the public work in collaboration with university members, 'in all phases of the research process, with a shared goal of producing knowledge that will be translated into action or positive change for the community' (Lantz et al. 2006, p. 239). As an approach to research with tenets that support active public engagement, participation in the decision-making or governance of community-based research therefore appears to be an essential and integral component. However, specific focus in the literature on the organisation and implementation of decisionmaking in community-based research is sparse, and there is a paucity of material which addresses the theory and practice of governing CBR, and the contributions of community members.In particular, participation in the governance of communitybased research appears to be poorly understood, understudied and underdeveloped (Barrington Research Group 2004). Not properly evaluating the importance of the public's participation in governance can limit knowledge production through research and potential benefits for communities. We were therefore interested in determining the experiences of community members in governing community-based research as a basis for understanding their participation, and designed a qualitative study to investigate this.
