Co-production in research: co-researcher perspectives on its value and challenges

Service user and public involvement in research (often referred to as patient and public involvement or PPI) is an important issue for health and social care practitioners, for whom co-production of research is perceived to be in line with professional person-centred values (Harries et al., 2019). In order to embrace this principle, we suggest that it is essential to understand how service users have historically been marginalised in research, a position that both reflects and perpetuates organisational policy and professional assumptions, attitudes and approaches.
