RT Journal Article SR Electronic T1 Using a community-based participatory research approach to meaningfully engage those with lived experience of diabetes and homelessness JF BMJ Open Diabetes Research & Care JO BMJ Open Diab Res Care FD American Diabetes Association SP e002154 DO 10.1136/bmjdrc-2021-002154 VO 9 IS 1 A1 David J T Campbell A1 Rachel B Campbell A1 Anna DiGiandomenico A1 Matthew Larsen A1 Marleane A Davidson A1 Kerry McBrien A1 Gillian L Booth A1 Stephen W Hwang YR 2021 UL http://drc.bmj.com/content/9/1/e002154.abstract AB Introduction Participatory research is a study method that engages patients in research programs, ideally from study design through to dissemination. It is not commonly used in diabetes health services research. Our objectives were to describe the process and challenges of conducting a participatory research project and to highlight the experiences of both patient co-researchers and academic researchers.Research design and methods We recruited people with lived experience of homelessness (PWLEH) and diabetes in Toronto, Canada to become patient co-researchers. They were asked to commit to attending biweekly meetings. We undertook two major research projects: concept mapping to choose a research focus; and photovoice to explore accessing healthy food while homeless. We used a convergent mixed-methods design to evaluate their experience.Results A diverse group of eight PWLEH had an average attendance of 82% over 21 meetings—despite this success, we encountered a number of challenges of conducting this research: funding, ethics approval and recruitment were particularly difficult. Group members reported that participation improved their ability to self-advocate in their diabetes care and provided them with tangible skills and social benefits. Group members stated that they valued being involved in all aspects of the research, in particular knowledge translation activities, including advocating for nutritious food at shelters; presenting to stakeholders; and meeting with policymakers.Conclusions The use of participatory research methods enables academic researchers to support community members in pursuing research that is pertinent to them and which has a positive impact. In our study, co-researchers contributed in meaningful ways and also valued the experience.No data are available. Given the small sample size of this study, it is impossible for the data to be truly anonymized, therefore due to ethical considerations, data are not being made available.
