Digital Lifestyle Intervention for Lung Cancer Survivors

Participants assigned to the intervention group receive access to a lifestyle mobile application for three months after rehabilitation or treatment has finished. The digital program is target group-specific and includes personalization and interactive elements without face-to-face appointments during the intervention. One virtual appointment at the beginning of the intervention with the study staff ensures that participants familiarize themselves with the mobile application and that they are assigned to a suitable program level. The intervention is mainly based on the following behavior change technique (BCT) clusters: goals and planning, feedback and monitoring, shaping knowledge, and comparison of behavior.
