Sumario:Bariatric surgery (BS) has proven to be the most effective treatment for weight loss and for improving comorbidities in severe obesity. A comprehensive psychological assessment prior to surgery is proposed to prepare patients for a successful post-surgical outcome. There- fore, the main aim of the present study was to assess psychological and personality predictors of BS outcome. The sample comprised 139 severely obese patients who underwent BS. Assessment measures included the Eating Disorders Inventory-2, the Symptom Checklist- Revised and the Temperament and Character Inventory-Revised. Our results show that favourable BS outcome, after 2 years follow up, was associated with younger age, less depression, moderate anxiety symptoms and high cooperativeness levels. Likewise, metabolic improvements were found to be linked to younger age and certain psychopathological factors. In conclusion, our findings suggest that age, baseline body mass index, psychopathological indexes and personality traits predict successful BS outcome.
