Materials and Methods: A prospective exploratory cohort study was conducted with two groups of patients who had undergone bariatric surgery: the DBT group received DBT group skills training sessions, while the control group received no intervention. Outcome measurements included BMI and scores of the Emotional Eating Scale (EES) and Mindful Eating Questionnaire (MEQ). Results: The study included 36 women: 18 in each group. In the DBT group, the interval from surgery was 11.17 +/- 7.12 months, and in the control group 10.89 +/- 5.74. Laparoscopic sleeve gastrectomy was done in 88.9% and 83.3% of patients in the DBT and control groups respectively. The rest underwent Roux-en-Y gastric bypass. The DBT group showed significant changes in overall and subscale scores of the EES and MEQ and BMI in kg/m(2) after 6 months of follow-up. BMI in kg/m(2) changed from mean +/- SD 35.45 +/- 6.17 to 28.47 +/- 4.28 in the DBT group, in control 35.88 +/- 5.07 to 31.56 +/- 3.71. The excess weight loss percentage (EWL%) in the DBT was mean +/- SD 75.3 +/- 17.9 and in the control was 63.6 +/- 14.5. In the DBT group, the EES score and MEQ score changed from mean +/- SD 45.06 +/- 20.19 to 20.50 +/- 13.40 and 11.52 +/- 2.02 to 15.87 +/- 1.92, respectively. The control group showed no significant change in scores. Conclusions: DBT skills training can reduce emotional eating, increase mindful eating, and facilitate weight loss after bariatric surgery.
