Adherence to independent exercise is an essential outcome of cardiac rehabilitation (CR), yet limited theory-based interventions to improve adherence exist. This study tested the effects of an intervention based on Bandura's conceptualization of self-efficacy. The self-efficacy coaching intervention (SCI), a supplement to standard care, was designed to increase self-efficacy for independent exercise and independent exercise behavior in CR. We examined whether the SCI vs. attention control (AC) resulted in improved exercise self-efficacy (ESE), barriers self-efficacy (BARSE), and minutes of independent exercise for CR participants (n = 65). While between-group differences did not reach significance (p >.10) for any of the outcome measures, significant within-group changes were noted in BARSE scores and independent exercise (p <.001) for the SCI group. Change in independent exercise for the AC group was also significant (p =. 006). Further study is needed to explore whether short-term changes translate into maintenance of independent exercise participation after program completion.
