| What it is | A digital health coaching program for cancer survivors, with weekly remote coaching, personalized evidence-based content, and daily monitoring of physical activity using a Fitbit device. | Assigned to standard survivorship care without immediate access to digital health coaching or Fitbit tracking. Participants may be offered the intervention after a delay. | Routine survivorship care without structured digital health coaching or wearable device–enabled monitoring. Typical follow-up includes office visits, referrals for support services, and general health counseling as needed. |
|---|
| Role in the trial | Investigational intervention arm; receives the active coaching and activity tracking for the main evaluation period. | Control arm; receives usual care without the new program during the main study period. | Reflects present-day survivorship care pathways outside clinical trial settings. |
|---|
| Primary use or purpose | To support cancer survivors' overall health and well-being by improving self-efficacy, physical activity, and quality of life through digital coaching and real-time feedback. | To provide a comparison group for evaluating the impact of the digital coaching program, participants receive only routine care during this period. | Structured to monitor recovery, manage late effects, and provide health advice for cancer survivors, predominantly through regular clinic follow-up and referrals. |
|---|
| How it is given or performed | Delivered remotely: weekly coaching calls, digital educational modules via text/email/app up to four times weekly, and continuous activity tracking through Fitbit. | Participants continue with usual care and have no access to digital coaching or device tracking; after the main study period, they may access the intervention. | Clinic visits occur at intervals determined by cancer type and stage. Advice on wellness, referrals, and symptom monitoring are provided by the clinical team; structured digital engagement is not routinely included. |
|---|
| Evidence status | Evidence from systematic reviews and smaller studies in cancer survivors suggests digital health coaching and e-health–supported self-management can improve fatigue, self-efficacy, and quality of life, but large, multicenter trials for broad survivor groups are underway. | Serves as the reference group for assessing impact of the digital program; does not receive additional intervention during the study assessment window. | Routine survivorship care provides ongoing clinical assessment and general support, but lacks structured digital self-management or device engagement. Meta-analyses suggest that such structured programs may confer additional benefit over standard care alone. |
|---|
| Important limitations | Requires access to a compatible smartphone or tablet, ability to engage in regular phone/digital sessions, and comfort with wearable technology. Effects for non-English speakers, those without internet/device access, or with severe comorbidities are less certain. | May experience delays in access to any potential program benefits, as participants only receive usual care during the study period. | Routine care may lack structured behavioral, emotional, and digital health support. Access to rehabilitation, psychosocial care, and systematic health behavior interventions may be inconsistent outside specialized clinics. |
