The feasibility, acceptability, and preliminary efficacy of a self‐advocacy serious game for women with advanced breast or gynecologic cancer

Cancer clinicians and systems aim to provide patient-centered care, but not all patients have the self-advocacy skills necessary to ensure their care reflects their needs and priorities. This study examines the feasibility, acceptability, and preliminary efficacy of a self-advocacy serious game (an educational video game) intervention in women with advanced breast or gynecologic cancer.Women with recently diagnosed (<3 months) metastatic breast or advanced gynecologic cancer were randomized 2:1 to receive a tablet-based serious game (Strong Together) (n = 52) or enhanced care as usual (n = 26). Feasibility was based on recruitment, retention, data completion, and intervention engagement. Acceptability was assessed via a postintervention questionnaire and exit interview. Preliminary efficacy was assessed on the basis of change scores from baseline to 3 and 6 months in self-advocacy (Female Self-Advocacy in Cancer Survivorship Scale) using intention-to-treat analysis.Seventy-eight women (55.1% with breast cancer; 44.9% with gynecologic cancer) were enrolled. Feasibility was demonstrated by satisfactory recruitment (69% approach-to-consent rate; 93% enroll-to-randomize rate), retention (90% and 86% at 3 and 6 months, respectively; 85% data completion), and intervention engagement (84% completed ≥75% of the game). Participants endorsed the intervention's (75%) and trial's (87%) acceptability. Participants in the intervention group experienced significant improvements in self-advocacy at 3 and 6 months compared to participants in the control group.Strong Together is feasible and acceptable among women with advanced breast or gynecologic cancer. This intervention demonstrates promising evidence of clinical efficacy. A future confirmatory trial is warranted to test the efficacy of the intervention for patient and health system outcomes.
