Study Summary

Home-based CR (HBCR) is an alternative to traditional CR programs that has comparable efficacy in improving morbidity/mortality and increases access to critical services. There is major potential to improve Veteran engagement in CR by combining digital coaching (d-Coaching) with existing VA-supported technologies. The investigator's theory-based intervention targets a critical component of successful CR engagement that is not available through traditional programs: virtual social support through a social network. In addition, the investigators propose to improve self-efficacy and self-regulation through interactive digital multi-media education, personalized feedback, and motivation so that Veterans can complete the prescribed HBCR program and maintain physical activity long-term. This RCT will evaluate the effects of HBCR alone (usual care) versus HBCR + d-Coaching, including a private social media group (Movn), optimized Annie text messaging, VA Video Connect, and connected devices (Fitbits). The investigators will randomly assign 150 Veterans from 2 HBCR programs to a 3-month intervention. The addition of d- Coaching to existing digital technologies will be operationalized by using a private social media group to provide social support, education, personalized feedback, and motivation. The investigators aim to determine the effect of the d-Coaching intervention on: a) the number of completed HBCR sessions over 3 months, b) functional capacity, c) physical activity, c) psychosocial outcomes, d) clinical outcomes, and e) social cognitive factors of self-efficacy, self-regulation, and perceived social support over 12 months. The investigators will also evaluate the extent to which self-efficacy, self-regulation, and perceived social support mediate the effect of the intervention on function and physical activity.
