Does coping strategies play a mediating role in the relationship between disease management self-efficacy and mental toughness with the quality of life of cardiovascular patients?

Background The present study was conducted with the aim of investigating the mediating role of coping strategies in relation to the self-efficacy for managing disease and mental toughness with the quality of life of cardiovascular patients. Method This was a descriptive-analytical cross-sectional study that was conducted in a specialized cardiology hospital in the west of Iran in 2022. The method of the present research is correlation structure analyses. Atotal of 313 eligible patients with coronary artery disease were included in the study. Coping strategies, self-efficacy for managing disease, mental toughness and quality of life questionnaires were used. After targeting 10 distorted questionnaires, 303 data were analyzed using SPSS version 26 and PLS_3 software. Results The results showed that self-efficacy and mental toughness are directly and indirectly related to the quality of life through the mediation of problem-oriented coping style, but SEM did not confirm this relationship through emotion-oriented coping style, and this relationship is not established. It was also found that heart patients with better self-efficacy for managing disease used more problem-oriented coping style, and their quality of life was reported to be higher. Conclusion The findings emphasize the importance of developing internal work models based on the type of coping strategies and the lifelong effects of these models on the quality of life of heart patients.
