Objective: To evaluate the effectiveness of a personalized motivational messaging intervention designed to improve cognitive function in lung cancer survivors. Hypothesis: Lung cancer survivors who receive personalized motivational messaging will demonstrate significantly greater improvements in cognitive function compared to those receiving standard care. Design and Participants: A randomized controlled trial (RCT) comprising 196 lung cancer survivors experiencing cancer-related cognitive impairment. Intervention: Participants in the intervention arm will be provided with a wearable activity tracker for three months and will receive personalized motivational messages via instant messaging applications (e.g., WhatsApp) to promote physical activity. The intervention comprises: (1) regular messages delivered at participant-preferred times and frequencies, enabling individuals to select from suggested physical activity goals; and (2) interactive, chat-based support facilitating goal setting, real-time counseling, and practical advice. The control group will receive an informational leaflet on cognitive impairment, along with text message reminders for follow-up assessments. Main Outcome Measures: Data collection will occur at baseline (T0), three months (T1; immediately post-intervention), and six months (T2; long-term follow-up). The primary outcome is cognitive function, assessed objectively via the Hong Kong version of the Montreal Cognitive Assessment (HK-MoCA) and subjectively via the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) scale. Secondary outcomes include physical activity levels (IPAQ-SF), exercise self-efficacy (SEE), psychological well-being (PHQ-4), and health-related quality of life (EORTC QLQ-C30). Data Analysis: Quantitative data will be analyzed using an intention-to-treat approach. Additionally, post-trial qualitative evaluations (to assess intervention compliance) and cost-effectiveness analyses will be performed. The study will strictly adhere to the CONSORT-EHEALTH reporting guidelines. Expected Outcomes: This trial will provide robust evidence regarding the effectiveness of the proposed intervention in mitigating cognitive impairment and increasing physical activity levels among lung cancer survivors.
