A Brief SMART Exercise Instant Messaging Support Intervention - a Pilot Study

Lung cancer is one of the most common cancer diseases, globally and locally. Several health benefits of increased physical activity (PA) have been reported for people with cancer. PA plays a critical role across the cancer trajectory, from prevention through to post-diagnosis and has been proposed as an alternative for improving physical and psychosocial health outcomes, reducing cancer recurrence, and cancer-specific and all-cause mortality. Although there are a variety of exercise intervention programs for cancer patients, those programs were quite intensive, requiring individuals to commit extra time and effort. Feeling of overwhelmed appointments, lack of time, other barriers, including high cost and limited access to facilities are the most frequently reported barriers that prevent people from starting and maintaining exercise. Hence, the investigators propose to use a brief messaging lifestyle modification intervention program to incorporating simple and easy-to-do patient-centred home-based lifestyle-integrated exercise into daily activities of patients with lung cancer. The aims are to explore the feasibility of using instant messaging to enhance physical activity and improve their fatigue, emotion and quality of life, and obtain feedback from patients for intervention and study design improvement.

Lung cancer is one of the most common cancer, globally and locally. Patients with lung cancer are in a uniquely challenging situation in their disease, comorbidities, and treatment that may lead to worsened symptoms and many negative health consequences, including fatigue, irritability, and impaired daytime functioning. Physical activity (PA) is defined as 'any bodily movement produced by skeletal muscle that results in energy expenditure'. Several health benefits of increased PA have been reported for people with cancer. PA plays a critical role across the cancer trajectory, from prevention through to postdiagnosis and has been proposed as an alternative for improving physical and psychosocial health outcomes, reducing cancer recurrence, and cancer-specific and all-cause mortality. Although there are a variety of exercise intervention programs for cancer patients, those programs were quite intensive, requiring individuals to commit extra time and effort. Most clinicians underutilise exercise therapy, regardless of its low-cost way to improve symptoms and potential health outcomes. Feeling of overwhelmed appointments, lack of time, other barriers, including high cost and limited access to facilities are the most frequently reported barriers that prevent people from starting and maintaining exercise. Low motivation, fear to exercise, lack of knowledge about benefits are the most common barriers of engaging in physical activity for cancer patients.

Hence, the current proposal is to use a brief messaging lifestyle modification intervention program to incorporating simple and easy-to-do patient-centred home-based lifestyle-integrated exercise (light to moderate physical activity) into daily activities of patients with lung cancer.

The aims are to explore the feasibility of using instant messaging to enhance physical activity and improve their fatigue, emotion and quality of life, and obtain feedback from patients for intervention and study design improvement.
