Background <p>Integrated knowledge translation (iKT) represents an approach to optimizing health interventions research through active collaboration between researchers and knowledge users throughout the research process. To date, few studies have explored the process of engaging in iKT, particularly in the context of multiple sclerosis (MS) research. Building on a larger iKT-informed study exploring mindfulness-based interventions for people living with MS, this study explores the perspectives of iKT panellists and extended collaborators on the use of iKT in health research.</p> Methods <p>This qualitative descriptive study utilized one-on-one semi-structured interviews conducted using Zoom or Microsoft Teams. Interviews were 20–30&#xa0;min in duration. An interview guide informed by the Ontario Brain Institute’s framework for patient engagement across the stages of research was used. Interviews were transcribed verbatim, coded, and analyzed using inductive thematic analysis.</p> Results <p>A total of eight iKT partners were interviewed, five were members of the iKT panel and three were extended collaborators. Five themes on the use of iKT in health interventions research on MS were identified: (1) defining iKT, (2) motivation and meaningful participation in iKT, (3) the importance of networking in iKT, (4) balancing multiple perspectives, and (5) barriers and facilitators to engaging in iKT. Within these themes, interviewees highlighted the need for further definition and operationalization of concepts. Discussion on the representativeness of iKT partners and recruitment of ‘hard to reach’ knowledge users was also salient.</p> Conclusion <p>The findings from this study provide useful considerations for other teams using an iKT approach. Future research directions include finding/maximizing meaningful ways for knowledge users to participate, exploring ways in which knowledge users could lead/co-lead (rather than consult on) research activities, and examining the potential role of an iKT facilitator.</p>
