Acknowledgements from the paper:
"The writing of this paper began at the first International Scientific Meeting on the Impact of Participatory Health Research organized by the International Collaboration for Participatory Health Research (ICPHR), the German Network for Participatory Health Research (PartNet), the Institute of Population and Public Health, Canadian Institutes of Health Research (CIHR), and Community-Based Research Canada (CBRC).
The conference took place in June 2015 at the Center for Interdisciplinary Research (ZiF) in Bielefeld, Germany. Experts in PHR from eleven countries met to launch an international discussion on what impact means in the participatory research process, how to maximize the impact of the research, and how to observe and document what impact has occurred.
At the Annual Working Meetings of the ICPHR in Malmo (2016), Limerick (2017) and finally Edmonton (2018) participants added their thoughts, ideas and comments. The Editorial Group would also like to acknowledge the helpful discussions and early comments provided by members of the UK Participatory Research Network who attended the Manchester 2015 meeting."
