Where experts and amateurs meet: the ideological hobby of medical volunteering on Wikipedia

The following paper advances our understanding of online volunteering in the medical context, through the study of Wikipedia volunteers who edit medical topics. It employs the Volunteer Functions Inventory (VFI) model to study volunteers' motivations through a survey carried out in 2021 (N=74). It highlights the importance of the non-traditional VFI dimensions of "fun" and "ideology" which have not been adequately discussed in the context of medical volunteering. The findings also show that Wikipedia volunteers who edit medical topics are older, more gender-balanced, and better educated than typical Wikipedia volunteers from a decade ago. Many are medical professionals, and their significant involvement helps to explain the above-average quality of Wikipedia medical topics. Conversely, the study reveals the need for more experts to engage with Wikipedia. Lack of volunteers, in particular, experts, and inadequate support from professional institutions, are identified as main reasons for problems in Wikipedia's quality.
