简要总结
Program ACTIVE II is a depression treatment study sponsored by the National Institutes of Health, Indiana University, Ohio University and West Virginia University. The purpose of this study is to test the effectiveness of two forms of treatment for depression for adults with type 2 diabetes: talk therapy (counseling) and exercise. Both of these forms of treatment have been proven to be effective in helping people with depression alone. In this study, the investigators will test to see if both of these approaches may be more effective in helping people live depression-free compared to talk therapy, exercise or usual care alone.
详细描述
Program ACTIVE II is a study funded by the National Institute of Diabetes and Digestive and Kidney Diseases (R18DK092765) designed to test the combined effectiveness of two behavioral treatments for depression in people with type 2 diabetes: individual counseling (cognitive behavioral therapy; CBT) and exercise. While each of these treatment approaches has been tested individually in people with depression, no study has tested the combination of these approaches for people with major depression and type 2 diabetes. These approaches have the potential to work synergistically as a win-win strategy to improve both T2DM and depression outcomes while extending the reach of formal health care treatment strategies for diabetes.
Two primary study aims will be addressed by Program ACTIVE II: 1) to compare changes in glycemic control across intervention groups to UC at POST and 6- and 12-month follow-up assessments; and 2) to compare changes in MDD outcomes across intervention groups (i.e. CBT, EXER, CBT+EXER) to usual care (UC) following intervention (POST) and 6- and 12-month follow-up assessments.
The primary hypotheses are:
- Diabetes Outcomes. Based on the investigators' pilot data, mean glycemic control (as measured by HbA1c) is expected to improve .4% in participants in the EXER and CBT+EXER treatment conditions at POST compared to baseline [de Groot et al 2009]. Participants assigned to the CBT+EXER treatment are expected to show the greatest improvement in HbA1c followed by those in the EXER group in comparison to the CBT group. No improvement is expected among those assigned to the UC condition.
- Depression. Participants in the CBT, EXER and CBT+EXER conditions will show clinically significant improvements in BDI and diagnosis of MDD at POST and 6- and 12-month assessments with the greatest improvements expected among those in CBT+EXER condition. Based on pilot data, a) 66% reduction in the number of people who meet DSM-IV criteria for MDD is expected at POST compared to baseline; b) 86-90% percent of cases with MDD remission at POST are expected to remain remitted at the 6-month follow-up; c) severity of depression, as measured by the BDI-II, will significantly decrease from baseline to POST and baseline to follow-up assessments, after co-varying the effect of gender, number of T2DM complications, and exposure to treatment. It is anticipated that participants in the CBT+EXER condition will show the longest remission rates of depression followed by those in EXER and CBT.
The secondary hypotheses are: 3. Changes in CVD risk factors in the intervention groups compared to UC over time. Physical activity capacity, as measured by the 6-minute walk test (6MWT), will demonstrate the greatest improvements in the CBT+EXER arm, closely followed by the EXER arm at follow-up assessment compared to baseline. Participants in the CBT and UC arms are not expected to show significant improvements. LDL-C is expected to improve at POST in the EXER and CBT+EXER conditions consistent with pilot data. 4. Cost Effectiveness Analyses. The predicted incidence of complications, particularly coronary heart disease (CHD), will be lower among those who receive CBT+EXER condition compared to the CBT, EXER and UC conditions. Further, the costs of this intensive intervention will be offset by a decrease in complication incidence.

研究组 & 干预措施
Talk therapy (CBT)
Participants randomized the talk therapy arm received 10 weeks of CBT or "talk therapy." The goal of CBT was to provide individuals with skills and concepts that they may use to: 1) manage and reduce depressive symptoms; 2) prevent the onset and severity of future depressive episodes; and 3) generalize these skills to diabetes management.
CBT interventionists facilitated patient management of depressive symptoms by providing participants with:
- Education about depression and the cognitive-behavioral therapy model;
- A safe relationship for participants to explore their symptom patterns and try to new tools to address them;
- Coaching as participants fully engage emotional and behavioral strategies.
干预措施: Program ACTIVE CBT (Behavioral)
Exercise (EXER)
Participants randomized to the exercise arm were enrolled in a 12-week physical activity intervention designed to increase aerobic physical activity. Participants were asked to complete 100 minutes of aerobic activity in Week 1, 125 minutes in Week 2, and 150 minutes per week of physical activity in Weeks 3-12. In addition, participants received 6 exercise training classes in which safe exercise practices were introduced and practiced, free access to a local exercise facility, use of a pedometer, completion of activity logs each week, and received an exercise workbook that addressed social and motivational aspects of physical activity.
干预措施: Program ACTIVE Exercise (Behavioral)
Talk therapy + exercise (CBT+EXER)
Participants randomized to the combination therapy received both talk therapy and exercise concurrently over a 12-week period as detailed above.
干预措施: Program ACTIVE (Behavioral)
Usual care (UC)
Participants randomized to usual care received no study intervention.
干预措施: Usual Care - No intervention (Behavioral)
结局指标
主要结局
Change in Depression Status - Beck Depression Inventory
时间窗: following completion of intervention (POST; ~3 months)
The BDI total score is a sum of 21 items (score range 0 - 63) with higher scores indicating greater depression symptomatology. We calculated change scores from baseline to POST (\~3 months). Negative values indicate improvements in depression symptoms. Positive values indicate worsened depression symptoms.
Change in Depression Status - Diagnosis of Major Depressive Disorder
时间窗: following completion of intervention (POST; ~3 months)
Data presented below is the proportion of participants in each treatment arm that achieved partial or full remission from MDD at POST (\~3 months) intervention per the Structured Clinical Interview for the DSM-IV.
Change in HbA1c
时间窗: following completion of intervention (POST; ~3 months)
Based on our pilot data, mean glycemic control (as measured by HbA1c) is expected to improve .4% in participants in the EXER and CBT + EXER treatment conditions at POST (\~3 month) compared to baseline (de Groot et al., 2009).
