OBJECTIVES: To find the significant correlations between diabetes distress, social support, self-efficacy, and performance of diabetes self-care activities in adults diagnosed with T2DM.

1. Increased levels of diabetes distress will be associated with decreased levels of social support,
2. Increased self-efficacy will be associated with decreased diabetes distress,
3. Increased social support will lead to an increase in self-efficacy,
4. Increased social support, increased self-efficacy, and decreased diabetes distress will be associated with increased performance in diabetes self-care activities.

METHODS: The study employed a correlational design to explore the relationships between diabetes distress, social support, self-efficacy, and performance of diabetes self-care activities. The study included a combination of objective and subjective self-report measures to ascertain the relationships between the variables of interest. A offline and online questionnaire survey of 2500 adults with Type 2 Diabetes Mellitus asked them about their self-care habits and psychological factors related to diabetes.

RESULTS: Diabetes distress and self-efficacy were significantly correlated. Diabetes distress and support satisfaction were associated with self-efficacy, but no relationships were found with other aspects of social support. No significant association was observed between psychosocial variables and self-care behaviors of diabetics in our study. However, psychosocial factors and self-care behaviours were associated with key health measures such as HbA1C and BMI.

CONCLUSIONS: Considering these psychosocial factors is important for healthcare practitioners, researchers, and individuals with type 2 diabetes. A diabetic's distress, self-efficacy, and social support should be evaluated and monitored in addition to self-care activities. Further investigation would benefit patients' ability to successfully self-manage T2DM in the future, depending on psychosocial and contextual factors. In addition to our findings, we contribute to expanding literature that explores how psychosocial and contextual variables influence the successful integration of DSM into daily routines.
