About

The proposed research seeks to determine whether virtual coaching and social support focusing on key social cognitive factors will be an effective strategy for maintaining physical activity (PA) after completing cardiac rehabilitation (CR). Despite the well-documented benefits of CR, only 15-50% of individuals continue to exercise 6 months after completing CR.4-6 Thus, after 36 sessions (typically 12 weeks), many patients are left without the support necessary to sustain physical activity (PA) and prevent adverse secondary cardiac events. Though previous research has explored interventions to sustain PA after CR, many studies have been lacking in a theoretical basis, objective measurement of PA, measurement, and analysis of psychosocial and social cognitive factors, and long-term impact on clinical outcomes. Low-cost, pragmatic approaches to maintaining PA after CR is urgently needed for older adults, and virtual technologies offer promising solutions to promote adherence to PA. The three specific aims of the project are to: 1) determine the effect of virtual coaching and social support on adherence to PA (measured by objective step counts) in the intervention vs. control groups; secondary measures will be amount of sedentary time, functional fitness, and self-reported exercise; 2) determine the effect of virtual coaching and social support on psychosocial and social cognitive factors in the intervention vs. control groups; 2a) evaluate the extent to which psychosocial and social cognitive factors mediate the effect of the intervention on PA adherence; 3) examine differences in CVD risk factors (blood pressure, lipids, HbA1c, BMI) between groups.

286 participants in 2 patient groups

Mobile App Alone
No Intervention group
Description:
Mobile app control group. Exposure time will be similar between participants in both the intervention and control groups as both will have: (1) continuous access to the app for self-monitoring of exercise, blood pressure, and weight; (2) weekly "push" text messages with access to a library of educational content for learning that is self-paced on the app over 6 months; and (3) assigned 1 video per month on a variety of health topics related to older adults via the app that match exposure time (approximately 20-30 minutes) with the intervention group. The videos will be created or resourced from reputable organizations. Our team will send weekly short one-way messages on goals, barriers, self-management, etc. that the intervention group will also receive. The 1-way messages will be derived from a bank of 210 secondary prevention messages for CVD (PA, nutrition, stress management, heart disease facts, etc.).
Mobile app + Social
Experimental group
Description:
The intervention group will also receive Virtual coaching. The coach will evaluate goals, progress, facilitators (use of the buddy system) and barriers with an emphasis on forming healthy PA habits that will be sustained long-term over the life course. Social support: For the social support component, we will provide ground rules for communication (e.g., positive posts, use of "likes", comments, etc.). Groups will be comprised of 4-6 participants with consecutive recruitment.
