Who Engages and Why It Matters?: Describing Participant Engagement in a Serious Game Intervention for Patients With Advanced Cancer.

While the use and benefits of serious games in health care are increasingly recognized, the impact of individuals' game engagement remains understudied, limiting the potential for impact. This pilot study aims to describe game engagement and its associations with learning outcomes, sociodemographics, and health factors in women with advanced cancer receiving a 12-week self-advocacy serious game intervention. Game engagement was collected from study tablets and weekly self-reported surveys. Participants' game engagement was overall high but with large amounts of variation and did not differ by their sociodemographics and health factors. Participants with lower baseline symptom severity were more likely to repeat game scenarios, and those who engaged in all scenarios had higher connected strength post-intervention. Knowing what prevents patients with advanced cancer from engaging in the serious game enlightens ways to refine the gamified interventions. Future research is suggested to evaluate patients' engagement to deepen understanding of its impacts on learning outcomes.
