Objective.To examine whether cognitive behavioral therapy (CBT) alleviates dysfunctional eating (DE) patterns and symptoms of anxiety and depression in morbidly obese patients planned for bariatric surgery.Design and Methods. A total of 98 (68 females) patients with a mean (SD) age of 43 (10) years and BMI 43.5 (4.9) kg/m2were randomly assigned to a CBT-group or a control group receiving usual care (i.e., nutritional support and education). The CBT-group received ten weekly intervention sessions. DE, anxiety, and depression were assessed by the TFEQ R-21 and HADS, respectively.Results.Compared with controls, the CBT-patients showed significantly less DE, affective symptoms, and a larger weight loss at follow-up. The effect sizes were large (DE-cognitive restraint,g=-.92,P≤.001; DE-uncontrolled eating,g=-.90,P≤.001), moderate (HADS-depression,g=-.73,P≤.001; DE-emotional eating,g=-.67,P≤.001; HADS-anxiety,g=-.62,P=.003), and low (BMI,g=-.24,P=.004).Conclusion.This study supports the use of CBT in helping patients preparing for bariatric surgery to reduce DE and to improve mental health. This clinical trial is registered withNCT01403558.
