I HEAL for Breast Cancer Survivors With Diabetes

The proposed randomized clinical trial evaluates a diabetes coping skills training (DCST) intervention for improving breast cancer survivors' abilities to manage symptoms and adhere to recommended diabetes self-management. The telephone-based DCST protocol integrates three key strategies to reduce symptoms and improve diabetes self-management: coping skills training for managing symptoms, adherence skills training, and healthy lifestyle skills training. The investigator will test the effects of the DCST intervention by comparing it to diabetes education alone. Physical symptoms, psychological distress, diabetes self-management behaviors, and self-efficacy for managing symptoms and diabetes self-management will be assessed at baseline and 3, 6, and 12 months. Physical activity (i.e., daily steps and distance) will be assessed using wireless activity trackers and data will be obtained from home blood glucose monitoring devices. Glycosylated hemoglobin (HbA1c) will be assessed at baseline, 6, and 12 months.
