Factors associated with quality of life in patients with type 2 diabetes mellitus: a cross-sectional study

Quality of life (QoL) is an important patient-centered outcome in type 2 diabetes mellitus (T2DM). Psychosocial and self-management factors, including Perception of illness, illness acceptance, self-care behaviors, and perceived social support, have been associated with QoL, but their relative associations remain insufficiently understood. This study examined these associations among patients with T2DM.

Data were collected using standardized questionnaires assessing general quality of life (SF12), illness acceptance, Perception of illness, self-care behaviors, and perceived social support.
