Construct a digital psychological intervention program for organ donor families: An Intervention mapping study

To develop a digital psychological intervention program for organ donor families based on Intervention Mapping.

Using Intervention Mapping, the program was developed through literature review, questionnaire surveys, and qualitative interviews, and then reviewed and refined by an expert panel.

The quantitative survey results showed 25.81% of 155 participants had co-occurring symptoms of post-traumatic stress, depression, and anxiety; trait mindfulness was negatively correlated with these symptoms (r=-0.423/-0.479/-0.463, p<0.001). Qualitative findings were organized into five themes: organ donation awareness, psychological distress, access to psychological support, psychological support needs, and willingness to use digital psychological interventions. Following the first four steps of Intervention Mapping, from needs assessment to program development, Acceptance and Commitment Therapy and Mindfulness-Based Stress Reduction were integrated in light of the needs of organ donor families, relevant literature, and expert input. Six experts participated in a panel review (collective authority coefficient=0.867) and refined an 8-week WeChat mini-program-based intervention delivered once weekly for 30 minutes per session.

The digital psychological intervention program for organ donor families developed through Intervention Mapping provides a structured, theory- and evidence-informed framework for subsequent psychological support. It may offer a basis for future pilot testing, refinement, and the development of digital mental health support strategies for organ donor families.
