Psychosocial Determinants of Bariatric Surgical Candidates and Outcomes

Although bariatric surgery is generally effective in treating morbid obesity, reducing risks of chronic disease, and improving quality of life, there remains considerable variability in patient outcomes; specifically why some patients maintain long-term weight loss while others are prone to lifestyle recidivism and weight regain. However, determining what drives that variability continues to elude researchers. The proposed research project seeks to provide insight into this variability by developing and employing a comprehensive bariatric assessment survey (CBAS) in order to determine what motivates individuals to seek bariatric surgery and how the specific procedure, financial cost, and location of surgical services correlate to their psychosocial functioning and outcomes over a two year period. This research will make a substantial contribution to the current literature by providing greater insight into this complex clinical population and improve understanding of what physical and psychosocial determinants most affect surgical outcomes. In doing so, this research may ultimately provide avenues to improve quality, efficacy, and efficiency of bariatric surgical services offered by the partner organization.
