Study Groups

First Intervention: Text Messaging, Second Intervention: Continued Text Messaging
Participants are first randomized to the low-intensity text messaging intervention. On 3 days/week they receive a text about 1 of the 3 behaviors (weight maintenance or loss, physical activity, and medication adherence) in randomized order with guidance for maintaining or improving these behaviors to reach program-provided goals. The system compares their last week's adherence to the responder criteria. They receive feedback praising adherence and instructions for a theory-driven behavioral strategy (e.g., stimulus control) to increase adherence. Feedback is tailored to the patient's adherence or existence of self-monitoring data. Participants meeting responder criteria after 2 months will continue to receive the text messaging intervention for the next 3 months.

First Intervention: Text Messaging, Second Intervention: Low-Intensity Cardiac Rehabilitation
Participants receive the text messaging intervention for 2 months. Following their mid-intervention assessment, they are randomized to receive the low-intensity cardiac rehabilitation maintenance program. Patients are instructed to log in 3 times weekly to view lessons, sync their Fitbit data, and complete a home-based workout video. They track weight, PA, and medication adherence daily. Patients have access to an extensive CR resource library made and curated by the platform provider plus resources on maintaining heart healthy behaviors during Phase III created by the research team. They are reminded to log in if they log in less than twice weekly.

First Intervention: Text Messaging, Second Intervention: High-Intensity Cardiac Rehabilitation
Participants receive the text messaging intervention for 2 months. Following their mid-intervention assessment, they are randomized to receive the high-intensity cardiac rehabilitation maintenance program. Patients are instructed to log in 3 times weekly to view lessons, sync their Fitbit data, and complete a home-based workout video. They track weight, PA, and medication adherence daily and attend a once weekly virtual meeting with a CR case manager. Meetings are modeled after Phase II and focus on tailored exercise prescription, addressing cognitive, behavioral, and environmental adherence barriers, and support.

First Intervention: Fully Automated Online Program (FAOP), Second Intervention: Continued FAOP
Patients receiving the fully automated online program will select a weight loss or a weight maintenance curriculum based on their goals. Patients will receive 8 weeks of fully automated lessons covering the 3 key behaviors: weight (management or loss), physical activity, and medication adherence. All 3 behaviors are discussed weekly, but the lessons first prioritize PA, then weight management, and then medication adherence to mimic the emphasis in Phase II. Total weekly lesson time is 20-30 minutes. Patients retain access to lessons. They self-monitor calories, weight, moderate-to-vigorous physical activity, and medication adherence. Tracking data are seamlessly integrated into the system. They manually enter their medication adherence data and receive encouraging feedback on each of the behaviors the next week. Participants meeting responder criteria after 2 months will continue to receive the fully automated online program.
