Purpose: The purpose of this study was to examine the relationships between treatment belief, personal control, depressive mood, and health-related quality of life in patients with hemodialysis based on self-regulation theory. Methods: Data were collected from 220 patients at 27 local hemodialysis clinics in Seoul during 2013 and 2014. The Revised Illness Perception Questionnaire, the Hospital Anxiety and Depression Scale, and Medical Outcomes Study Short Form-12 were used to measure outcome variables. Data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson correlation, and multiple regression using the 'enter' method. Results: Treatment belief and personal control scored 3.58 and 3.54 out of 5 points respectively, on average. Treatment belief and personal control of kidney disease were negatively correlated with depressive mood and positively correlated with health-related quality of life. According to the regression analysis, treatment belief, monthly income, and personal control were discovered to account for 21.8% of the variance in depressive mood, where as depressive mood, monthly income, treatment belief, and age were found out to account for 40.6% of the variance in health-related quality of life. Conclusion: Our study demonstrated significant positive relationships between treatment belief and illness outcome in hemodialysis patients. Interventions aimed to provide the necessary information and trust to maximize the effectiveness of treatment need be developed to improve patients outcomes.
