What this Trial Is About
Researchers are evaluating a mobile health (mHealth) intervention designed to help colorectal cancer (CRC) survivors and their family caregivers follow lifestyle recommendations that may improve symptoms, health outcomes, and quality of life. The study focuses on developing a digital tool tailored to CRC survivors and caregivers to encourage adherence to nutrition and physical activity guidelines recommended by the American Cancer Society. The intervention includes using the Healthy Buckeyes app for goal setting, self-monitoring, social support, time management, and relapse prevention. Participants wear a Fitbit, use exercise bands, watch weekly short videos on healthy lifestyle strategies, and receive health coaching over 10 weeks. The study has multiple phases, including design, user-experience testing, and a 12-week pilot, where survivor-caregiver pairs engage in app-based activities and support each other. Participants will complete interviews, surveys, and think-aloud sessions to provide feedback on the app and intervention content. Researchers will assess usability, acceptability, recruitment, adherence, and retention rates over up to one year. The study involves monitoring participant engagement through the app and wearable devices to understand the program's effects and feasibility in improving lifestyle behaviors among CRC survivors and their family caregivers.
