Objective: The aim of this study was to examine validity and reliability of Turkish version of Yale Food Addiction Scale (YFAS) among Turkish bariatric surgery patients. Methods: The YFAS scale was administered to obese patients (n=171) who were seeking or underwent bariatric surgery. Construct validity of the scale was evaluated with factor analysis and reliability was evaluated with item-total score correlation and repeatability were tested by intraclass correlation (ICC) analysis between test-retest results. Results: Internal concistency was found adequate Kuder-Richardson Formula 20 coefficient (KR-20) 0.822, and Cronbach’s alpha 0.859 for the entire 25-item YFAS. As Bartlett's Test of Sphericity was significant, the factor model developed in the present study was decided appro-priate. Factor analysis extracted six factor in Turkish YFAS that explained for 67.51% of the total variance. Item total correlation coefficients of scale ranged from 0.214-0.666. Conclusion: Our findings support the use of the Turkish YFAS as a reliable measure of food addiction among bariatric surgery patients.
