Although there is a growing recognition of the significance of co-creators’ experience (CCE) to the success of the process and potential impact on the co-created output, there is a gap in the aggregation of the literature regarding their experience. The aim of this scoping review was to explore empirical research on CCE among adults in all contexts. Two databases were searched, the Health CASCADE database and SCOPUS, retrieving over 11,000 papers. After removal of duplicates and thorough screening, almost 50 papers were included in the review. Preliminary findings reveal a mix of positive experiences, like enjoyment, and negative experiences, such as frustration, during co-creation. Moreover, both positive and negative psychological impacts from involvement in co-creation have been reported, such as increased knowledge or dissatisfaction with the process. These results offer valuable insights into co-creators’ participation and engagement. By understanding their experiences, we can enhance the co-creation process and maximize its impact.
