Summary
Self-efficacy, a belief in one's ability to succeed, significantly predicts heart disease management behaviors in older women. Enhancing self-efficacy may improve medication adherence, exercise, stress management, and diet.
Area of Science:
- Health Psychology
- Behavioral Science
- Gerontology
Background:
- Social cognitive theory emphasizes self-efficacy as crucial for behavior change.
- Prospective studies on self-efficacy in health behavior are limited.
- Understanding self-efficacy's role in chronic disease management is vital for older adults.
Purpose of the Study:
- To examine self-efficacy as a prospective predictor of disease management behaviors.
- To investigate self-efficacy beliefs across multiple health behaviors in older women with heart disease.
- To explore the reciprocal relationship between self-efficacy and health behaviors.
Main Methods:
- Longitudinal study design with 570 older women diagnosed with heart disease.
- Baseline assessment of self-efficacy and disease management behaviors.
- Follow-up assessments at 4 and 12 months postbaseline.
- Statistical analysis to determine self-efficacy as a predictor of behaviors.
Main Results:
- Self-efficacy was a statistically significant predictor (p<.05) of multiple disease management behaviors.
- Predictive power was observed at both 4 and 12 months postbaseline.
- Behaviors predicted included medication adherence, exercise, stress management, and dietary compliance.
- R2 statistics indicated modest but significant predictive influence.
Conclusions:
- Building self-efficacy is a potentially effective strategy for interventions.
- Interventions should aim to enhance self-efficacy for improved heart disease management.
- Findings support self-efficacy as a key target for promoting health behaviors in older women with heart disease.
