Abstract
BACKGROUND: This study tested the effects of a multicomponent exercise training intervention called "Heart Failure Exercise And Training Camp" (HEART CAMP). The intervention was theoretically derived from Bandura's social cognitive theory. METHODS: An experimental repeated-measures design was used. Participants were randomized to the HEART CAMP intervention group (n = 22) or the attention control group (n = 20). Participants were compared on self-efficacy for exercise, symptoms, physical function, and quality of life over 12 weeks. RESULTS: The intervention group had a 31% increase in cardiac exercise self-efficacy and significantly fewer symptoms compared with the attention control group. Quality of life increased significantly in both groups. CONCLUSION: A theory-based intervention improved self-efficacy for exercise and symptoms in patients with heart failure.
