Self-esteem is the variable that regulates an individual's self-evaluation and self-concept. A high self-esteem is indicative of a high self-worth and a positive social inclusion. A low self-esteem can lead to psychological distress such as depression, anxiety, and isolation. The objective of this study is to examine whether or not the bariatric weight loss treatment has the potential for adverse psychological issues among the self-esteem of the obese female patient. Bariatric surgery is a popular treatment choice among those obese female individuals who have not been successful with conventional weight loss methods such as diets and exercise. The bariatric surgery intervention has been identified as the most effective weight loss treatment program, but very little research exists that has explored the potential for adverse issues. This research design of a repeated measure, between-groups and posttest study, utilizing the Rosenberg Self-Esteem Scale (RSE), investigates self-esteem at the presurgical, 4-month postsurgical, and 1-year postsurgical stages after weight loss has occurred to explore the potential for adverse psychological issues.
