This research project case focuses on the use of multiple participatory research platforms to explore the experience of multiplicity within young adult populations; multiplicity refers to the experience of having more than one person within a single body. The issues and approaches discussed are relevant across a range of participant populations who may find less frequently used participatory methods more accessible. The case study outlines the transferable learnings from one study, including the use of an online consultation model and social media platforms, as well as the researcher’s reflections on the respective strengths and limitations. The importance of using appropriate methodologies when researching traditionally underrepresented groups will also be examined, with specific examples used. The process of developing a positive, inclusive project that draws on the expertise of the participants will be outlined.
