MindOnLine, a self-guided online mindfulness program supporting people living with cancer: Participant satisfaction analysis

Purpose This study evaluated participant satisfaction with MindOnLine, a 9‑week self‑guided online mindfulness program designed to support psychological wellbeing among people living with and beyond breast, prostate, or colorectal cancer. It examined perceptions of usability, emotional coping support, and influence on ongoing mindfulness practice. Methods Embedded within a larger randomised controlled trial, this survey‑based study collected quantitative and qualitative data from intervention‑group participants at program completion. Program satisfaction, session usefulness, and overall helpfulness were assessed using Likert‑scale measures across multiple domains, alongside four open‑ended questions exploring mindfulness practice, managing difficulties, future use, and desired content. Quantitative data were summarised descriptively. Open‑ended responses were analysed thematically using Braun and Clarke’s framework, with categories generated by human coders and Microsoft Copilot© compared to enhance analytical rigour. Results Of 233 intervention participants, 167 (72%) provided satisfaction data. Most reported that the program was easy to use (91%) and would recommend it to others (83%). Between 41% and 59% noted improved emotional understanding and coping, including decreased anxiety (54%) and increased control over thoughts (59%). Thematic analysis of 267 qualitative responses identified four overarching themes: (1) transformative benefits during and beyond cancer; (2) empowerment through sustained mindfulness practice; (3) individualised and practical program experiences; and (4) integration of mindfulness amid competing life demands. Conclusion MindOnLine was acceptable, empowering, and emotionally beneficial, with most participants intending to continue mindfulness practice. Findings highlight the value of flexible, person‑centred digital mindfulness interventions in cancer survivorship care and offer guidance for scalable implementation.
