Abstract

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 (R2 = 0.02) and PFS-Tr was positively correlated with DEBQ (r 0.497 p < 0.001).

Conclusion: This is the first study that validates and reports the Turkish version of PFS and the results of our study show that PFS-Tr is a valid and reliable tool for determining the tendency for the hedonic hunger in Turkish adult population.

Level of evidence: Level V, cross-sectional descriptive study.

Keywords: Eating behavior; Hedonic hunger; Power of food scale; Turkish population.
