Psychopathology, Disordered Eating, and Impulsivity as Predictors of Outcomes of Bariatric Surgery

This study will evaluate the relationship between psychopathology, disordered eating, and impulsivity (measured by clinical interview, self-report measures, and objective testing) on changes in weight and psychosocial status in the first two years after bariatric surgery. Participants will be 300 adults who plan to undergo bariatric surgery. Participants will complete four assessments over a two-year period, one at baseline (before surgery) and 6, 12, and 24 months after surgery. Each assessment will include computer tasks, surveys, clinical interview, urine test, waist circumference and height/weight measurement. The investigators will track how psychopathology, disordered eating, and impulsivity are related to changes in weight and psychosocial status following bariatric surgery.
