EFFECTIVENESS OF DIABETES SELF-MANAGEMENT EDUCATION (DSME) AND FAMILY-BASED INTERVENTIONS ON QUALITY OF LIFE IN PEOPLE WITH TYPE 2 DIABETES Diabetes is a health condition that can have a significant impact on quality of life. Therefore, self-care management and family support may be important in helping people with diabetes maintain or improve their quality of life. The purpose of this study was to evaluate the effectiveness of the Diabetes Self-Management Education (DSME) program and family-based interventions in improving the quality of life of people with type 2 diabetes. This research was conducted using a quasi-experimental design with a one-group pre- and post-test. A sample of 54 individuals was selected using purposive sampling technique. Analysis was performed using dependent and independent t-tests. The results indicated that the DSME program was effective in improving quality of life in all domains (p < 0.05). Family-based interventions were shown to improve quality of life (p = 0.045) and psychological (p = 0.010) and environmental (p = 0.029) domains. However, the two interventions did not appear to differ in improving quality of life (ppre = 0.727; ppost = 0.466). The study concluded that DSME and family-based interventions are effective in improving quality of life in people with type 2 diabetes. These interventions can be implemented in other health care settings.
