Summary

This prospective study investigates the roles of various pre-surgical psychosocial variables on weight loss and quality of life changes after bariatric (weight-loss) surgery. Patients complete a number of questionnaires inquiring about psychological distress, eating behaviours, and social factors (e.g., social support) prior to surgery, and are following for 12 months after surgery. Understanding predictors of outcomes following bariatric surgery will help in patient selection, resource allocation, and identifying at-risk patients for appropriate psychosocial intervention to support outcomes after surgery.
