Depression and illness-specific distress are more common among adults with Type 1 diabetes (T1DM) than the general population and have been associated with poorer control of blood glucose and increased risk for serious diabetes-related complications. Treatment nonadherence has also been associated with depressive symptoms and diabetes-related distress, and has repeatedly been suggested as an important modifiable behavioral pathway linking depression and diabetes outcomes. The present study reports on the feasibility and acceptability of a pilot intervention using group-based cognitive-behavioral therapy to improve treatment adherence among adults with T1DM and elevated levels of diabetes-related distress or depressive symptoms. We describe the components of the intervention and utilize qualitative data along with descriptive outcome data. Our findings suggest that participation in the group was acceptable and associated with reductions in depressive symptoms and diabetes-specific distress. Challenges to feasibility and future directions are discussed.

Research has found that depression is more common among individuals with diabetes and is associated with worse diabetes outcomes including treatment nonadherence, worse glycemic control, higher risk of diabetes complications, greater functional impairment, and increased risk of mortality. These patterns of association have led to an increase in research investigating the relationship between diabetes and depression. There remain important questions about the relationship between depression and diabetes and an unmet need for treatment approaches that are successful in ameliorating depression and improving diabetes outcomes. The current commentary discusses several conceptual issues related to the measurement of depression in diabetes, argues for the importance of health behavior and treatment adherence in approaching the problem of depression in diabetes, and provides an example of a treatment approach that incorporates the treatment of depression with strategies aimed at improving treatment adherence in order to maximize effects on diabetes outcomes.
