Validation of the Italian version of the Power of Food Scale in the adult population.

Purpose: The Power of Food Scale (PFS) is designed to measure the personal susceptibility to highly processed and palatable foods. The purpose of this study was to validate the Italian version of PFS (PFS-It) in the adult population.

Methods: Data were obtained from 536 Italian adults aged between 18 and 86 years. The PFS-It and the Binge Eating Scale (BES) were administered to all participants.

Results: The factorial structure of the PFS-It was investigated using a CFA that returned excellent fit indices. The Cronbach's alpha coefficients for the PFS-It total score and for its subscales (Food Available, Food Present, and Food Tasted), as well as for the BES total score, revealed good to moderate reliability. Finally, PFS-It was positively and significantly correlated with BES.

Conclusion: To our knowledge, this is the first study to propose the norms and psychometric characteristics of the Power of Food Scale in an Italian population. The results show that PFS-it is a valid and reliable instrument for the measurement of Hedonic Hunger in an adult Italian population.

Level Of Evidence: Level V, cross-sectional descriptive study.
