In the article by De Panfilis et al. [ [1] De Panfilis C. Generali I. Dall’Aglio E. Marchesi F. Ossola P. Marchesi C. Temperament and one-year outcome of gastric bypass for severe obesity. Surg Obes Relat Dis. 2014; 10 (143–7) Abstract Full Text Full Text PDF PubMed Scopus (22) Google Scholar ], the authors present the findings of a study examining the associations between various dimensions of temperament and weight loss 1 year after Roux-en-Y gastric bypass surgery. The authors previously published findings suggesting that patients with higher scores on the temperament dimension of persistence, defined as the ability to sustain behavioral efforts despite obstacles and temptations, had better weight loss outcomes at 1 year after laparoscopic adjustable gastric banding [ [2] De Panfilis C. Cero S. Torre M. et al. Utility of the temperament and character inventory (TCI) in outcome prediction of laparoscopic adjustable gastric banding: preliminary report. Obes Surg. 2006; 16: 842-847 Crossref PubMed Scopus (27) Google Scholar ]. Not only does their most recent study extend the previous findings to patients undergoing a different surgical procedure, but the authors also have improved on their previous study’s design by controlling for Axis I and II disorders in their analyses. As in the laparoscopic adjustable gastric banding study, the authors found here that the trait of persistence was related to better weight loss outcomes after Roux-en-Y gastric bypass surgery, even when controlling for the potentially confounding factors of both Axis I pathology and personality disorders. Impressively, the trait of persistence was found to account for 40% of the variability in weight loss in this sample, an unusually robust finding among studies of psychosocial predictors of weight loss surgery (WLS) outcomes. The findings of this study have important implications for both empirical and clinical practice.

This study evaluated whether temperament traits influence weight loss 1 year after gastric bypass, controlling for the potential confounding effect of Axis I and II disorders. Full-Text PDF
