CBT for Adherence and Depression in Diabetes
CBT for Adherence and Depression in Diabetes

This study will evaluate the effectiveness of cognitive behavioral therapy (CBT) in treating people with depression and type 2 diabetes.

Depression is a serious illness that affects a person's mood, thoughts, and physical being. Common symptoms of depression include persistent feelings of anxiety, guilt, or hopelessness; irregular sleep and appetite patterns; lethargy; disinterest in previously enjoyed activities; excessive irritability and restlessness; suicidal thoughts; and inability to concentrate. Depression is highly comorbid, often occurring in the presence of one or more other disorders. Up to 15% to 20% of the time, people with diabetes are also depressed. Diabetes is a disease that interferes with the body's proper production and use of the hormone insulin, which is needed to convert food into the energy required to perform daily life activities. Self-care is a crucial component of diabetes treatment. However, symptoms of depression can interfere with behaviors necessary to carry out this care. Cognitive behavioral therapy (CBT) has shown success in treating people with depression, but the effect of CBT on self-care behaviors and depression of those with diabetes is not well known. This study will evaluate the effectiveness of CBT for medical adherence and depression (CBT-AD) in people with a depressive mood disorder and type 2 diabetes.

Upon study entry, all participants will complete various assessments, including a psychiatric diagnostic interview, a series of paper questionnaires, neuropsychological testing, blood sample analysis, and blood sugar monitoring. Next, all participants will meet with a nutritionist and a nurse diabetes educator. The nutritionist will help set goals for eating, physical activity, weight, and blood glucose. The nurse diabetes educator will review diabetes medication history and blood glucose self-monitoring equipment.

Participants will then be randomly placed in one of two counseling groups. One group will meet for a single session that will be devoted to diabetes medical adherence. The other group will attend 10 to12 individual CBT sessions for diabetes medical adherence and depression management. The CBT sessions will last 45 to 50 minutes and will require practice of coping skills outside the sessions. Participants receiving CBT will also complete weekly assessments of depression, self-care, and diabetes medical adherence. All participants will be asked to monitor a prescribed medication with a pill cap for the course of the study. At Month 2, participants in both groups will also meet again with the nutritionist to review original goals and adjust them as necessary. Most of the previous study assessments will be repeated at Months 4, 8, and 12. The neuropsychological testing will be repeated only at Month 12.

Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
  • Diabetes Mellitus
  • Depression
  • Behavioral: Enhanced treatment as usual plus adherence training
    The single-session life-steps treatment targets informational, problem solving, and cognitive-behavioral steps that are geared toward improving medication adherence and diabetes self-management.
  • Behavioral: Enhanced treatment as usual plus CBT-AD
    The multiple-session CBT treatment is given after completion of the life-steps session. The CBT sessions focus on treatment of depressive symptoms as well as adherence to diabetes self-care.
  • Active Comparator: Enhanced treatment as usual
    Enhanced treatment as usual plus single-session life-steps treatment
    Intervention: Behavioral: Enhanced treatment as usual plus adherence training
  • Experimental: CBT-AD
    Enhanced treatment as usual plus multiple-session CBT treatment (CBT-AD)
    Intervention: Behavioral: Enhanced treatment as usual plus CBT-AD
