Trajectories of Resilience and Bariatric Surgery Outcomes

A high prevalence of psychological trauma on one hand and of psychiatric disorders, such as depression, anxiety, suicide attempts, addictions, and eating disorders on the other hand, has been reported in patients with severe obesity seeking bariatric surgery. Some studies reported an increased prevalence of these psychiatric disorders after bariatric surgery, potentially related to weight regain. In this context, psychological resilience is a concept that brings together internal and external factors of adaptation, and whose clinical use facilitates interdisciplinary collaborative work. This research focuses on the association between resilience and success or failure of bariatric surgery in patients followed in the Specialized Obesity Center (CSO) of the Nancy University Hospital. The hypothesis is that psychological resilience before surgery promotes successful surgical treatment. This retrospective study is based on existing data from patients with severe obesity who have undergone bariatric surgery at the Nancy CSO. The main objective is to study 1) the resilience of patients with severe obesity, candidates for bariatric surgery, at the first assessment (T0), at the end of lifestyle/behavioral modifications program (T1) and at 2 years after bariatric surgery (T2), 2) the relationship between internal and external factors explaining resilience and final weight outcomes. The investigators are expected that non-resilient patients have more psychological vulnerabilities (psychopathology, negative life events, etc.), and have lower weight loss than resilient patients.
