About this trial

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.
