Abstract

Diabetes self-management education (DSME) is a cornerstone of comprehensive diabetes care, equipping 
individuals with the knowledge, skills, and confidence required to effectively manage their condition and reduce 
the risk of complications. This narrative review examines the conceptual foundations, delivery models, 
effectiveness, and implementation challenges of DSME programs, with particular emphasis on clinical, behavioral, 
psychosocial, and quality-of-life outcomes. Evidence from systematic reviews and longitudinal studies consistently 
demonstrates that DSME improves glycemic control, self-care behaviors, psychosocial well-being, and patient 
empowerment. Reductions in glycated hemoglobin (HbA1c), enhanced medication adherence, improved dietary 
and physical activity practices, and better health-related quality of life are among the most frequently reported 
outcomes. Program effectiveness is influenced by duration, intensity, delivery format, and degree of 
personalization, with longer interventions and hybrid face-to-face and digital models showing superior outcomes. 
Psychosocial components including motivation, self-efficacy, and social support play a central role in sustaining 
behavior change. Despite strong evidence of benefit, participation and adherence to DSME programs remain 
suboptimal, particularly among older adults, individuals with low socioeconomic status, rural populations, and 
ethnically diverse groups. Structural barriers, social determinants of health, and health-system constraints 
significantly affect access and engagement. Addressing these challenges requires culturally responsive program 
design, policy support, and integration of DSME within routine clinical care. Strengthening evaluation 
frameworks and quality improvement strategies will be essential to maximize the reach, equity, and long-term 
impact of DSME programs.
