This study applied a cross-sectional design to examine the relationship between self-management, psychological well-being, and quality of life in patients with hypertension and evaluated the mediation effect of psychological well-being on self-management and quality of life. Through purposive sampling, this study enrolled 255 patients with hypertension from the cardiology department of a teaching hospital in Taiwan. Mediation effects were estimated using linear regression and the Sobel test. Age, number of chronic diseases, waist circumference, self-management, and psychological well-being explained 18.7% of the total variance in quality of life. Psychological well-being partially mediated the effects of self-management on quality of life, with a total effect of 19.2%. Psychological well-being is an important factor correlated with self-management and quality of life in patients with hypertension.
