Researchers are evaluating the effects of a digital lifestyle intervention on health-related quality of life HRQoL in survivors of non-small cell lung cancer NSCLC. Lung cancer survivors often experience ongoing symptoms like fatigue and breathing difficulties after treatment, which can lower their physical and psychological functioning. This study aims to support survivors beyond treatment by promoting physical activity, healthy eating, and breathing and relaxation exercises. Participants will be randomly assigned to either use a self-management mobile application focused on physical activity, nutrition, and breathingrelaxation for three months or receive usual care without changes to their planned treatments. The mobile app includes personalization and interactive features and one virtual appointment to help users get familiar with it and set appropriate goals. The intervention is based on behavior change techniques such as goal setting, feedback, and monitoring. Throughout the study, participants will be assessed on changes in overall and lung cancer-specific quality of life, physical activity, exercise capacity, psychological distress, fatigue, nutrition risks, and self-rated health over three months. Researchers will monitor these outcomes regularly to understand the interventions impact. The study period lasts three months, during which participants will complete questionnaires and other evaluations related to their health and well-being.
