It is currently unknown what makes some obese individuals opt for bariatric surgery whereas others choose not to. The aim of this study was to examine whether personality characteristics differed between obese individuals signed up for Roux-en-Y gastric bypass (RYGB) (N=30) and obese individuals not seeking RYGB (N=30) compared to non-obese controls (N=30). All participants completed the NEO Personality Inventory-Revised. The obese RYGB group displayed higher levels of Neuroticism and borderline lower levels of Extraversion compared to the obese non-RYGB and the non-obese group, while the two latter groups did not differ in terms of personality. The Neuroticism domain and possibly the Extraversion domain may therefore be worthwhile to consider in future studies investigating the outcome of bariatric surgery.
