Predicting Bariatric Surgery Outcomes in Severe Obesity Using Preoperative MMPI-2-RF Questionnaire Results

What this Trial Is About

This research aims to study patients with severe obesity who are considered for bariatric surgery. It evaluates how psychological factors measured before surgery, such as depression, anxiety, eating behaviors, quality of life, body satisfaction, and body perception, relate to changes in body mass index BMI after surgery. The goal is to identify risk factors that might affect surgery success and help tailor therapies before surgery to improve outcomes. The study collects data in two phases. The first phase gathers preoperative clinical information and results from the MMPI-2-RF psychological questionnaire completed before surgery. The second phase involves collecting postoperative data during routine follow-up visits, where patients complete additional psychological questionnaires including the Patient Health Questionnaire PHQ-9, Generalized Anxiety Disorder GAD-7, Three Factor Eating Questionnaire TFEQ-R21, Quality of Life for Obesity and Dietetic Questionnaire EQVOD, Body Esteem Scale BES, and Figure Rating Scale. Participants will be involved through data collection of their psychological assessments before and after surgery, along with clinical follow-up. Researchers will measure how preoperative psychological dimensions predict BMI changes over time. The study also monitors which patients may abandon surgery plans and explores factors related to postoperative difficulties. Participation includes routine consultations and questionnaire completion, with the study continuing until 2027.
