Predicting Health-Related Quality of Life based on Emotion Regulation with Mediating Role of Self-Care in Patients with Coronary Artery Disease

Objective: Coronary Artery Disease is a chronic and complex disease requiring continuous medical care. The current study was conducted to predict Health-Related Quality of Life based on emotion regulation with mediating role of self-care in patients with Coronary Artery Disease (CAD). Method: The research method was descriptive-correlational. The statistical population comprised all patients with CAD (N=350) referring to Shohadaye Tajrish Hospital in Tehran, Iran, in the second half of 2020. Based on the Tabachnick Fidell formula, 184 subjects were selected using a convenient sampling method. Research instruments were the Self-Care Scale (Jaarsma, Halfens, Tan et al, 2003), Emotion Regulation Questionnaire of Garnefski and Graich (2001), and HRQol Survey (Ware, Kosinski Keller, 1996). Data analysis was done using Structural Equation Modeling (SEM) and path analysis. Results: The results indicated a positive and significant mediating role of self-care in the relationship between emotion regulation (β= 0.175, p 0.01) and HRQoL of patients with CAD. Moreover, self-care and emotion regulation had a positive impact on HRQoL. Conclusion: According to the findings, a part of the mutual effect of self-efficacy and emotion regulation on HRQoL is explained by self-care. On the other hand, high emotion regulation and self-care led to better HLQoL of CAD patients.
