Abstract

This study determined the effectiveness of a self-efficacy intervention designed to improve self-efficacy and physical activity in older adults postcardiac event. An experimental three-group design tested the intervention, with treatment groups receiving 1 of 2 supportive telephone protocols (theory-based self-efficacy coaching or attention control). Outcome variables included self-efficacy expectations for physical activity (PA), self-reported PA, and PA performance (distance walked in 6 minutes). The self-efficacy intervention was effective in demonstrating greater PA performance when compared to the attention control intervention, and PA self-efficacy was significantly correlated with both measures of PA. There were significant main effects of time for PA self-efficacy and distance walked, and a significant interaction effect on the distance walked because of time and treatment condition. Although the self-efficacy intervention did not show a direct effect on level of PA self-efficacy as hypothesized, there was an indirect interaction effect on distance walked and physical activity confidence.
