Bariatric surgery is an increasingly popular intervention for obesity, and psychologists have seen a growing role in the evaluation of surgery candidates. Studies of pre-surgery psychosocial and physical health variables that are predictive of post-surgical outcome have been inconclusive. In the present study, pre-operative health status, psychological testing results, and support group attendance were measured to determine their relationship with weight-loss outcome at 6 months post-surgery. The Health Perception scale of the Health Status Questionnaire was a significant predictor of weight loss outcome. This suggests that individuals who endorse more negative perceptions of their physical health are more likely to have a better outcome post-surgery. The results of this study emphasize the importance of evaluating an individual’s psychological perceptions of their physical health when they present for bariatric surgery.
