Objective: The aim of this study is to identify psychosocial variables associated with the relationship between weight loss and change in depressive symptoms following gastric banding surgery. Methods: Ninety-nine adults completed self-report questionnaires assessing depressive symptoms and other psychosocial variables (self-esteem, body image dissatisfaction, perceived physical health, and perceived weight-based stigmatisation) prior to gastric-band surgery and monthly for 6-month post-surgery. Results: Weight, depressive symptoms, and other psychosocial variables improved significantly 1-month post-surgery and remained lower to 6 months. Weight loss from baseline to 1- and 6-months post-surgery significantly correlated with change in depressive symptoms. Body image dissatisfaction and self-esteem accounted for some of the variance in change in depressive symptoms from baseline to 1-month and baseline to 6-months post-surgery. Conclusions: Depressive symptoms improved significantly and rapidly after bariatric surgery, and body image dissatisfaction and self-esteem predicted change in depressive symptoms. Interventions targeting body image and self-esteem may improve depressive symptoms for those undergoing weight loss interventions.
