Abstract

Objectives. To investigate the relationships among self-efficacy, changes in self-efficacy, past exercise participation, future exercise adherence, and exercise program format. Methods. Two-year randomized trial involving subjects (n = 63) participating in an aerobic exercise program. Subjects were randomly assigned to one of three exercise conditions: higher-intensity home-based exercise, higher-intensity class-based exercise, or lower-intensity home-based exercise. Results. Results indicated that baseline self-efficacy and exercise format had significant (p <.02), independent effects on adherence during the adoption and early maintenance phases of exercise behavior. In contrast, in predicting long-term exercise program maintenance, a significant (p <.05) self-efficacy X exercise format interaction indicated that self-efficacy predicted adherence only in the supervised home-based exercise conditions. Results also suggest that baseline self-efficacy, independent of the effect of past adherence, significantly (p <.03) predicted exercise adherence during the adoption phase, but not early maintenance phase, of exercise behavior. Finally, adherence change during the adoption phase of exercise behavior significantly (p <.04) predicted Year-one levels of self-efficacy even after adjusting far the effect of baseline self-efficacy. Conclusions. These results suggest that exercise program format as well as an individual's initial cognitive and behavioral experiences in an exercise program play significant roles in determining exercise adherence.
