Comorbidity is associated with decreased confidence or self-efficacy to perform self-care in heart failure patients which, in turn, impairs self-care behaviors. Comorbidity is also associated with increased hospitalization rates and poorer quality of life. Yet the manner in which comorbidity and self-efficacy interact to influence self-care, hospitalization, and quality of life remains unclear.
