Abstract
Purpose: Among cancer survivors, physical activity (PA) is associated with reductions in cancer recurrence, morbidity, and mortality. Most adolescent and young adult (AYA) survivors do not attain adequate PA. Digital modalities, specifically wearable activity monitors with a paired mobile application (app) and private social media group for support offer a promising approach for promoting PA among AYAs. We conducted a pilot randomized controlled trial of this intervention. To evaluate its acceptability and perceptions of the intervention components, we conducted qualitative interviews with those in the intervention.
Methods: Semi-structured qualitative interviews with 13 AYA cancer survivors ages 18-39 who participated in the intervention assessed perceptions of the digital components of the study and buddy system of nominating a friend to participate in PA with the survivor. Analyses included a qualitative thematic analysis of the interview transcripts and coded interview segments into three predetermined categories: facilitators, limitations, and suggestions.
Results: Participants spoke of the wide-ranging benefits of the intervention, citing the Fitbit device and “buddy system” as major motivators to engage in PA and reach goals. Most participants noted feelings of increased physical and emotional wellness. The most-cited limitation of the intervention was the automated text messages, which participants found impersonal. Suggestions for improvement included integrating more elements of competition and group challenges.
Conclusions: This digital PA intervention was perceived as feasible and acceptable to AYA cancer survivors and appears promising for promoting PA and improving long-term health and quality of life.
