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.
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.
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.
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.

食物力量量表（PFS）旨在测量个体对高度加工且美味食物的易感性。本研究的目的是在成年人群中验证意大利语版的PFS（PFS-It）。
数据来自536名年龄在18至86岁之间的意大利成年人。所有参与者均接受了PFS-It和暴饮暴食量表（BES）的测试。
使用验证性因素分析（CFA）对PFS-It的因子结构进行了研究，得出了极佳的拟合指数。PFS-It总分及其子量表（可得食物、呈现食物和品尝食物）以及BES总分的克朗巴哈α系数显示出良好至中等的信度。最后，PFS-It与BES呈显著正相关。
据我们所知，这是第一项提出意大利人群中食物力量量表的常模和心理测量特征的研究。结果表明，PFS-it是测量成年意大利人群享乐性饥饿的有效且可靠的工具。
