Traditional mindfulness-based stress reduction programs require prolonged daily practice (e.g., 45 minutes over 8 weeks) and show low adherence in this population, largely due to cancer-related fatigue. Brief mindfulness sessions (10-20 minutes) delivered via widely-used instant messaging platforms may improve accessibility and adherence compared with standalone apps or websites that require additional learning effort.\n\nThis is a two-arm, parallel-group randomized controlled trial evaluating a LINE chatbot-delivered brief mindfulness intervention (Mindbot) combined with VR-guided audio-visual content, compared with usual care, among cancer patients admitted to a hospital ward at a medical center in northern Taiwan.\n\nRandomization: Participants are allocated 1:1 using an online randomizer (Sealed Envelope Simple Randomiser) with random permuted blocks of mixed sizes 4 and 6. The allocation sequence is generated by an independent researcher not involved in recruitment, and allocation results are concealed in sequentially numbered, opaque sealed envelopes until after consent and eligibility confirmation. To reduce cross-contamination among roommates in shared hospital rooms, all participants in the same room are assigned to the same study arm.\n\nBlinding: Because the intervention is delivered via a distinguishable QR code (chatbot vs. existing hospital app), participants and on-site research staff cannot be blinded to allocation. After data de-identification and re-coding, the statistician performing the primary analysis is blinded to actual group assignment until the primary analysis is complete.\n\nIntervention: The experimental arm receives automated push notifications at 13:00 and 21:00 daily, prompting a 10-minute structured mindfulness session (breath awareness, body scan, and mindful acceptance of hospital ambient sounds), guided by the virtual character \"Mindbot\" in a VR environment. Each session includes a pre- and post-practice assessment of cancer symptom severity and a 7-minute resting heart rate variability (HRV) measurement. The control arm receives usual hospital care and access to the hospital's existing health management app, which provides general disease-related e-education without mindfulness content.\n\nOutcome assessment: Primary outcomes (mindfulness level, perceived stress, HRV, salivary cortisol) and secondary outcomes (fatigue, cancer symptom severity) are assessed at baseline (T0, at enrollment), hospital discharge (T2), and the first outpatient follow-up visit (T3). Salivary cortisol is additionally sampled four times daily (on waking, 30 minutes post-waking, afternoon, and late evening) throughout the intervention period. Qualitative feedback shared by participants through the LINE chat interface is de-identified, transcribed, and analyzed using content analysis to complement the quantitative findings.",[44,50],{"label":45,"type":46,"description":47,"interventionNames":48},"Mindbot Brief Mindfulness Chatbot","EXPERIMENTAL","Participants receive a LINE chatbot (\"Mindbot\") delivering a 10-minute structured brief mindfulness session (breath awareness, body scan, and mindful acceptance of ambient sounds) combined with virtual reality (VR)-guided audio-visual content, with automated push reminders at 13:00 and 21:00 daily, for the duration of their hospital stay.",[49],"Behavioral: Mindbot: Brief Mindfulness-Based LINE Chatbot with Virtual Reality",{"label":51,"type":52,"description":31,"interventionNames":31},"Other: Usual Care","NO_INTERVENTION",[54],{"type":55,"name":56,"description":57,"armGroupLabels":58,"otherNames":31},"BEHAVIORAL","Mindbot: Brief Mindfulness-Based LINE Chatbot with Virtual Reality","A LINE chatbot (\"Mindbot\") delivering a 10-minute structured brief mindfulness session (breath awareness, body scan, and mindful acceptance of ambient hospital sounds) combined with virtual reality (VR)-guided audio-visual content.
