Smartphone App-Based Mindfulness Intervention for French and English Speaker Cancer Survivors

Study acronym: SEAMLESS

Active, Not Recruiting

Summary

There is a need to develop, evaluate, and disseminate self-directed, easily accessible, safe, affordable, and effective psychosocial interventions to people living with cancer (PLWC) post-treatment. Smartphone app-based health interventions are an innovative way to deliver psychosocial cancer-care. The Mindfulness-Based Cancer Survivorship (MBCS) Journey app is a mobile app format of the Mindfulness-based Cancer Recovery program. In the SEAMLESS Study, the investigators aim to evaluate the MBCS Journey app (a 4 week mind-body intervention) in cancer survivors post-treatment. This is a randomized wait-list controlled trial. Participants will either be assigned into the immediate group (will receive intervention immediately after enrollment) or the waitlist group (wait for 3 months before receiving the intervention).
