Diabetes Distress and Self-Efficacy Mediate the Relationship Between Family Function and Coping in Young and Middle-Aged Patients with Type 2 Diabetes Mellitus

As the first study confirming dual-channel mediation in this population, we demonstrate that diabetes distress and self-efficacy functioned as parallel mediators in the relationship between family function and coping and adaptation ability. Healthcare professionals are encouraged to incorporate family-focused interventions into the management of T2DM. Reducing psychological stress and routinely monitoring self-efficacy levels are crucial for enhancing patients' coping and adaptation ability.
