Design and effectiveness evaluation of a web-based microplatform for mindfulness intervention for organ donor family members.

Background: Organ transplantation technology provides life-saving treatment for patients with end-stage organ failure. However, family members of donors face psychological harm due to the urgent decision-making process regarding organ donation and the associated stigmatization, highlighting an urgent need for mental health support. Methods: This study used the User Version of the Mobile Application Rating Scale (uMARS) to screen domestic mindfulness-related applications, analyzed the functions of high-quality applications, and combined with previous surveys, designed and developed a web-based mindfulness intervention micro-platform for families of organ donors based on the Information-Motivation-Behavioral Skills (IMB) model. The effectiveness of the micro-platform was verified through a pre-post self-controlled trial. Results: The platform consists of seven functional modules: "Understanding Mindfulness", "Psychological Science", "Practice Room", "Community Exchange", "Psychological Quiz", "Daily Mindfulness" and "Personal Center", and provides professional mindfulness courses and mental health education resources. The results of the effectiveness evaluation indicate that the platform has a positive effect on alleviating negative emotions such as Post-Traumatic Stress Disorder (PTSD), depression and anxiety among family members. Conclusions: The present study has developed a web-based mindfulness intervention micro-platform for families of organ donors, which is effective in alleviating negative emotions such as Post-Traumatic Stress Disorder (PTSD), depression and anxiety among family members, as well as in improving sleep quality.
