Abstract: b i Background: /i /b High levels of depression and poor self-efficacy and self-management are associated with worse glycemic control, but the linkage and pathway between these variables are poorly understood. We conducted this study to investigate the hypothesis that self-efficacy and self-management mediate the influence of depression on poor glycemic control. b i Methods: /i /b We studied a purposive s le of 142 adults with type 2 diabetes attending a public clinic in Ilam, Iran. Hierarchical linear regression analysis and structural equation modeling were used to explore the relationships among the variables of interest. b i Result: /i /b Depression directly and negatively affects self-efficacy and indirectly affects self-management behaviors, which in turn have direct effects on hemoglobin A1c (HbA1c). Self-efficacy mediates the relationship between depression and self-management behaviors. Self-efficacy and self-management behaviors partially mediate the effect of depression on HbA1c. These results confirmed that the data fit the hypothesized model very well. b i Conclusion: /i /b Careful monitoring of glycemic control might be important in those in iduals who exhibit clinical signs of depression. Effective treatment programs should probably pay close attention to not only screening and treatment of depression but also skills training to enhance patient self-efficacy and self-management of diabetes to improve HbA1c.
