Prediction of Response to Bariatric Surgery in Patients With Severe Obesity

Centre Hospitalier de Moulins Yzeure360 enrolled

Overview

This is an retrospective and prospective (ambispective) study with data collection from volunteer patients who passed an MMPI-2-RF (Minnesota Multiphasic Personality Inventory-2-Restructured form) questionnaire in the preoperative phase of a bariatric surgery project. The evolution of their BMI will be correlated to psychological dimensions collected in patient questionnaires, before and after bariatric surgery. The presence of possible risk factors such as depression, anxiety, eating disorders, quality of life, satisfaction and the perception of body, could make it possible to establish adapted therapies before surgery, in order to attenuate or eliminate the presence of these factors, and improve BMI evolution and bariatric surgery success.

A first phase of data collection will concern data from the MMPI-2-RF questionnaire as well as clinical data, collected during preoperative consultations. For the second phase, post-operative data will be collected, during a routine follow-up consultation in the nutrition Department, where specific psychological questionnaires are taken by patients.
