Diabetes mellitus is a chronic condition requiring sustained self-management behaviors influenced by individual capacities, social support systems, healthcare structures, community resources, and health policies. This observational study adopts the Social Ecological Model and Orem's Self-Care Deficit Theory to evaluate the combined effects of socio-ecological determinants and health literacy on self-management agency.
Data will be collected using structured questionnaires, including adapted health literacy and self-care agency scales, along with researcher-developed instruments assessing socio-demographic variables and socio-ecological determinants. Path analysis will be employed to examine direct and indirect relationships among study variables.
