Key result
Self-efficacy strongly predicts physical activity in CHF, explaining ~38% of the variance.
Why the study?
What are the predictors of physical activity levels in patients with well-compensated chronic heart failure?
Cross-Sectional (n=43)
What are the predictors of physical activity levels in patients with well-compensated chronic heart failure?
p-value: p=0.015
Self-efficacy is a stronger predictor of physical activity performance than measures of physical fitness or perceived exertion in patients with chronic heart failure.

Self-efficacy may guide activity counseling in chronic heart failure; leaves open whether targeted interventions improve outcomes in prospective trials.
Oka et al. (1996) conducted a cross-sectional in chronic heart failure (n=43). Self-efficacy and other personal/environmental variables was evaluated on physical activity levels (p=0.015). Self-efficacy was the strongest predictor of physical activity in patients with chronic heart failure (p=0.015), with the overall predictive model explaining 38% of the variance (p<0.001).
