Bariatric surgery is the most effective treatment for severe obesity, yet a significant percentage of patients achieve suboptimal results or present long-term weight regain. Given the strong association between poor outcomes and post-surgery psychological factors, it is crucial to implement post-surgical psychological interventions. This randomized controlled trial aims to compare the efficacy of a novel, cost-effective, and timely-personalized treatment delivering strategy (stepped-care) with two different intensities 1) low-intensity intervention delivered by Facebook®, and 2) high-intensity program delivered online. It is also intended to study predictors, outcome moderators/mediators, and the underlying mechanisms of weight regain. Participants' assessment will include measures of pathological eating behavior, psychological impairment, negative urgency, and emotional regulation.
