Do psychological variables predict weight loss in obese individuals after bariatric surgery?

The intervention is a take home questionnaire pack which will take ~1 hour to complete, and a 1 session with interviewer which will last between 1- 2 hours The aim of this psychological assessment study is to identify baseline psychological correlates which may help predict individuals who are more or less likely to achieve minimal weight loss goals after LAGB surgery. LAGB placement provides a safe and reliable method of achieving and sustaining significant weight loss in the majority of obese patients. It consists of placing an adjustable silicone gastric band just below the gastroesophageal junction. The band is adjustable by injection of saline into a peripherally placed reservoir. A psychological assessment is part of standard protocol for Bariatric Surgery in the US, however, there is no data to date evaluating its effectiveness in the treatment of obesity. Therefore, the study aims to evaluate the use of interviews in bariatric surgery. In addition to the inclusion of bariatric and psychiatric interviews, psychological constructs measuring stress, social support, mood, coping, motivation and self-efficacy will also be investigated through the use of paper and pencil questionnaires. Successful screening and identification of individuals who are unlikely to achieve minimal weight loss goals could potentially reduce patient distress and such individuals could be directed to more suitable weight loss approach. It is also important to understand factors which may inhibit or reduce weight loss in those individuals in order to maximise weight loss outcomes.
