Abstract
Purpose The mechanism by which depression influences health outcomes in persons with diabetes is uncertain. The purpose of this study was to test whether depression is related to self-care behavior via social motivation and indirectly related to glycemic control via self-care behavior. Methods Patients with diabetes were recruited from an outpatient clinic. Information gathered pertained to demographics, depression, and diabetes knowledge (information); diabetes fatalism (personal motivation); social support (social motivation); and diabetes self-care (behavior). Hemoglobin A1C values were extracted from the patient medical record. Structural equation models tested the predicted pathways. Results Higher levels of depressive symptoms were significantly related to having less social support and decreased performance of diabetes self-care behavior. In addition, when depressive symptoms were included in the model, fatalistic attitudes were no longer associated with behavioral performance. Conclusions Among adults with diabetes, depression impedes the adoption of effective self-management behaviors (including physical activity, appropriate dietary behavior, foot care, and appropriate self-monitoring of blood glucose behavior) through a decrease in social motivation.Keywords
