a comprehensive intervention for diabetes and comorbid depression in primary care

Conditions: Type 2 Diabetes; Major Depressive Disorder

Summary: the study involves a 32-week randomized controlled trial in primary care of a comprehensive diabetic and depression intervention in patients with type 2 diabetes and comorbid mdd, compared to a group treated with usual care for mdd plus disease self-management and measurement-based care for diabetes.

the overarching goal of the study is to translate research-based treatment procedures that have been shown to improve outcomes for both dm and mdd for use in primary care. more specifically, the aims are: 1) to evaluate the benefits of cddi in improving diabetic outcomes compared to usual care for mdd plus disease self-management for diabetes; 2) to evaluate the benefits of cddi in improving depression outcomes compared to the uc for mdd treatment protocol; and 3) to evaluate the benefits of cddi in terms of improved (1) cardiovascular risk factors (blood pressure, body mass index, lipids, and abdominal fat), (2) levels of exercise and better diet, (3) clinician and patient satisfaction with care, (4) fidelity to treatment guidelines, and (5) cognitive function.
