Conceptualising, operationalising and measuring trust in participatory health research networks: a scoping review protocol

A participatory approach to co- creating new knowledge in health research has gained significant momentum in recent decades. This is founded on the described benefits of community- based participatory research (CBPR), such as increased relevance of research for those who must act on its findings. This has prompted researchers to better understand how CBPR functions to achieve these benefits through building sustainable research partnerships. Several studies have identified ‘trust’ as a key mechanism to achieve sustainable partnerships, which themselves constitute social networks. Although existing literature discuss trust and CBPR, or trust and social networks, preliminary searches reveal that none link all three concepts of trust, CBPR and social networks. Thus, we present our scoping review protocol to systematically review and synthesise the literature exploring how trust is conceptualised, operationalised and measured in CBPR and social network
