Validation of the Turkish version of the power of food scale in adult population

Purpose The Power of Food Scale (PFS) is a tool for measuring the hedonic impact of food environments rich in palatable foods. The purpose of this study was to validate the Turkish version of PFS (PFS-Tr) in a large adult population. Methods Data were obtained from 505 Turkish adults aged between 19 and 64 years. The PFS-Tr and Dutch Eating Behavior Questionnaire (DEBQ) were completed by all participants. Results PFS-Tr compared with the original English version of PFS, items 5 and 13, which showed the highest error covariance under the food available factor. To provide general criteria, items 5 and 13 were removed. After these two items were removed, the Cronbach’s alpha coefficient was 0.922 for PFS-Tr and Cronbach’s alpha values for “food available”, “food present”, and “food taste” were found to be 0.849, 0.797, and 0.82, respectively. Besides, the Cronbach’s alpha coefficient was 0.93 for DEBQ. In addition, a linear association was found between BMI and mean score of PFS-Tr with a model fit ( R 2 = 0.02) and PFS-Tr was positively correlated with DEBQ ( r 0.497 p
