To provide better care and preventive services for people with both depression and diabetes, the investigators propose to develop and test whether interventions to reduce depressive symptoms can be integrated into routine diabetes clinics in India. The investigators will gather feedback from patients in India through focus group discussions and individual interviews so they can culturally-adapt a model of combined depression and diabetes care. The investigators will then evaluate the effectiveness and costs of this care model in a trial at three diabetes clinics in India. It is expected that results from this study can guide how to incorporate mental health care into routine diabetes clinics in low-resource settings.
