PURPOSE
This study aimed to examine the mediating role of physical activity in the relationship between depressive symptoms and health-related quality of life in patients with coronary artery disease.
METHODS
A descriptive cross-sectional study design was conducted using the data from the 2016 Korea Community Health Survey. The participants comprised 6,072 patients with coronary artery disease aged 19 years or older. Depressive symptoms, physical activity, and health-related quality of life were assessed. The collected data were analyzed by a complex sample test using SPSS/WIN 24.0 program. Bootstrapping methodology was utilized to examine the mediating role of physical activity in the relationship between depressive symptoms and health-related quality of life with SPSS PROCESS macro Model 4.
RESULTS
The results of the hierarchical linear regression analysis showed that depressive symptoms (t=−22.37, p<.001) and physical activity (t=12.12, p<.001) were significant predictor of health-related quality of life. A mediation analysis further revealed that physical activity mediates the relationship between depressive symptoms and health-related quality of life.
CONCLUSION
This study suggests that the negative impact of depressive symptoms on health-related quality of life can be improved through physical activity. Healthcare providers should consider these finding during early assessment of depressive symptoms in patients with coronary artery disease. Moreover, developing intervention strategies to enhance the level of physical activity could improve health-related quality of life of patients.

PURPOSE
The purpose of this study was to construct and test a predictive model for physical activity adherence for secondary prevention among patients with coronary artery disease.
METHODS
Two hundred and eighty-two patients with coronary artery disease were recruited at cardiology outpatient clinics in four general hospitals and the data collection was conducted from September 1 to October 19, 2015.
RESULTS
The model fit indices for the final hypothetical model satisfied the recommended levels: χ2/dF=0.77, adjusted goodness of fit index=.98, comparative fit index=1.00, normal fit index=1.00, incremental fit index=1.00, standardized root mean residual=.01, root mean square error of approximation=.03. Autonomy support (β=.50), competence (β=.27), and autonomous motivation (β=.31) had significant direct effects on physical activity adherence for secondary prevention among patients with coronary artery disease. This variable explained 35.1% of the variance in physical activity adherence.
CONCLUSION
This study showed that autonomy support from healthcare providers plays a key role in promoting physical activity adherence for secondary prevention among patients with coronary artery disease. The findings suggest that developing intervention programs to increase feelings of competence and autonomous motivation through autonomy support from healthcare providers are needed to promote physical activity adherence for secondary prevention among patients with coronary artery disease.
