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 appropriate. 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. [Anadolu Psikiyatri Derg 2015; 16(0.100): 44-53]
