Cognitive behavior therapy significantly reduces depression, diabetes distress, and health anxiety while improving quality of life and treatment adherence in patients with type 2 diabetes.
Abbas et al. (2022) conducted an RCT in Type 2 Diabetes Mellitus with depressive symptoms (n=90). Cognitive Behavior Therapy vs. Waitlist control was evaluated on Diabetes distress (Diabetes Distress Scale score at 16 weeks) (η2 0.788, p=<0.001). Cognitive behavior therapy significantly decreased diabetes distress (η2=0.788) and depression (η2=0.611) compared to a waitlist control condition in patients with type 2 diabetes mellitus.
