International youth mental health case study of peer researchers' experiences.

Background: The involvement of young people as peer researchers, especially with lived experience, is increasingly considered important in youth mental health research. Yet, there is variation in the understanding of the role, and limited evidence on its implementation across different research systems. This case study focusses on the barriers and enablers of implementing peer researcher roles within and across majority world countries contexts. Methods: Based on an international youth mental health project involving different levels of peer researchers and participants from eight countries, peer researchers and a co-ordinating career researcher reflect on lessons regarding enabling and challenging factors. These reflections are captured and integrated by a systematic insight analysis process. Results: Building on existing international networks, it was feasible to actively involve peer researchers with lived experience in a multi-country mental health study, who in turn recruited and engaged young participants. Identified challenges include the terminology and definition of the role, cultural differences in mental health concepts, and consistency across countries and sites. Discussion: Peer researchers' role could be strengthened and mainstreamed in the future through ongoing international networks, training, sufficient planning, and active influence throughout the research process. Trial registration: Not applicable. Plain English summary: The involvement of young people with lived experience as collaborators (peer researchers) in mental health research has become more prominent in recent years. Yet, there is variation in the understanding of this role and how to involve young people. There is also limited evidence on how this role can be applied across different research systems, especially in majority world countries. We share our experience from a youth mental health project involving peer researchers in eight countries. Peer researchers and the co-ordinating career researcher reflected on lessons regarding enabling and challenging factors. Their reflections highlighted that, overall, it is feasible to successfully involve young people with lived experience in international mental health research. Several challenges were also identified, including terminology, definition of roles, cultural differences in understanding mental health, and consistency across participating countries and sites. According to peer researchers' reflections, these challenges can be overcome through the establishment of ongoing international networks, training and support, sufficient planning and peer researchers getting involved at all the stages of the research. Lessons from this case study can be of interest to the international research community in strengthening the involvement of young people in mental health research. [ABSTRACT FROM AUTHOR]
