Objective: Comorbidity with depression is a critical issue in dealing with diabetes type 2. Any intervention for diabetes treatment must consider the psychological dimensions associated with it. The aim of the present study is to assess the effectiveness of group cognitive behavior therapy (CBT) on depression and quality of life of women with diabetes type 2.

Method: The sample included 30 diabetic women comorbid with depression who were randomly divided into the experimental and control groups. The subjects received 10 sessions of group cognitive behavioral therapy and filled out Beck s Depression Inventory (BDI) and Quality of Life Scales befor and after the intervention.

Results: Using MANCOVA shows that the intervention in the experimental group decreased the depression symptoms (F=72.17, p<0.001) and improved quality of life(F=8.82, p<0.05) in the compared to the control group. The results were statistically significant at p<0/05.

Conclusion : The findings suggest that applying cognitive behavior therapy could help in decreasing the psychological symptoms related to diabetes type 2 and subsequently increase the patients’ quality of life.
