User experiences, usability, and social presence of a peer-to-peer support app: survey of young adults affected by cancer

Young adult (YA) cancer survivors often experience social isolation. Mobile apps facilitate peer-to-peer connections, yet little is known about their use. YA survivors (N = 181) were surveyed about a peer-to-peer cancer support app. Among those with it downloaded, 36% reported daily/weekly use. One-to-one messaging and group chat features were easy-to-use and useful, but facilitation of social presence was variable. Within group chats, 55% participated in discussions; 45% observed conversations without contributing. The app was helpful for convenient access to peer support (84%), particularly when offline social networks were inadequate (83%); some (16-25%) reported nervousness initiating connections. Qualitative feedback identified facilitators and barriers to adoption and sustained engagement. Recommendations centered on improving design and logistical factors and facilitating in-app connections. App-based peer support is promising for addressing social isolation among YA survivors. Future research should examine theory-based communication and design features to encourage meaningful engagement and longitudinal effects on psychosocial outcomes.
