Feedback Using behaviOral econOmic Theories on STEP countS in Cardiovascular Disease Patients

The three aims of this randomized controlled trials; 1. To demonstrate the effectiveness of loss framing in gamification for achieving increased physical activity in patients with CVD. 2. To demonstrate the effectiveness of social support in gamification for achieving increased physical activity in patients with CVD. 3. To evaluate the impact of the intervention using social incentives and social support through gamification on changes in participants; subjective assessment of physical activity levels, body mass index (BMI), and lipid panel in blood tests. Secondary Objective: 1. To assess whether the differences between study groups in achieving the goal of increased physical activity during the 6-week intervention period persist during the 6-week follow-up period. 2. To investigate how the increase in physical activity through gamification in patients with CVD is influenced by patients; behavioral characteristics and environmental factors. This trial will be a five-group, randomized controlled trial (RCT) with an intervention period of 6 weeks and a follow-up period of additional 6 weeks.
