Therefore, the present study aimed to examine the relationship between self-care based on illness perception with social support, shared decision-making, and self-efficacy in patients with type 2 diabetes. The research method was descriptive-correlational. In a cross-sectional survey, 800 patients with type 2 diabetes (331 men and 469 women) were selected through random sampling from hospitals in Qom Province. Data were collected using a demographic and illness perception questionnaire, the Family Social Support Questionnaire, the Self-Efficacy in Diabetic Patients Questionnaire, the Diabetes Self-Care Questionnaire, and the Patient Participation in Treatment Decision-Making Questionnaire. Data analysis was conducted using SPSS 26 software. The results indicated a significant positive relationship between self-care based on illness perception with social support, shared decision-making, and self-efficacy. Considering the findings, it can be concluded that self-efficacy, belief in treatment effectiveness, social support, diabetes severity, and type of treatment are crucial factors in performing self-management behaviors and can explain a substantial proportion of the variability in diabetes self-management.</p> self-care illness perception social support shared decision-making self-efficacy https://journals.kmanpub.com/index.php/Health-Nexus/article/download/3663/5635
