What this trial studies

This observational study collects data from patients who have undergone psychological evaluation using the MMPI-2-RF questionnaire before bariatric surgery. It aims to correlate changes in body mass index (BMI) with psychological factors such as depression, anxiety, and eating disorders. By analyzing both preoperative and postoperative data, the study seeks to identify risk factors that could affect the success of bariatric surgery and to develop tailored therapies to improve outcomes. The research will involve both retrospective and prospective data collection from patients treated in the Nutrition department.

Who should consider this trial

Good fit: Ideal candidates are patients with severe obesity who have completed the MMPI-2-RF questionnaire and are being considered for bariatric surgery.

Not a fit: Patients who have not undergone bariatric surgery due to medical contraindications or those who object to the use of their data will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved psychological support and better outcomes for patients undergoing bariatric surgery.

How similar studies have performed: While similar studies have explored psychological factors in bariatric surgery, this specific approach of correlating MMPI-2-RF results with BMI changes is relatively novel.
