RESUMO
BACKGROUND: Adaptive cognitive emotion regulation (CER) strategies toward eating play a very important role in obesity and according to schema therapy, patients with obesity learn that don't respond to their emotional stimuli by eating. Thus, this study aimed to evaluate the effectiveness of an online video-based group schema therapy in improvement of the CER strategies and body mass index (BMI) in women who had undergone bariatric surgery. METHODS: Forty women who had undergone sleeve gastrectomy were selected and randomly divided into two groups of control and experimental. The experimental group received 10 weekly 90-min sessions of group schema therapy, the control group did not receive any intervention at all. Both groups completed the CER strategies questionnaire during pre-test, post-test and follow-up stages, and the data were analyzed using a multivariate analysis of covariance (MANCOVA) through SPSS software (version 20). RESULTS: Our results indicated that the experimental group demonstrated significantly higher adaptive CER strategies (P = 0.0001, F = 31.15) and significantly lower maladaptive CER strategies (P = 0.001, F = 9.42), significantly lower BMI (P = 0.001, F = 23.48), as compared to the control condition, following the group schema therapy after the follow-up stage. CONCLUSION: The findings demonstrated that group schema therapy could lead to an increases in adaptive CER strategies and a decrease in maladaptive CER strategies and BMI in women who had undergone bariatric surgery.
