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.
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.
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 = 0.02) and PFS-Tr was positively correlated with DEBQ (r 0.497 p < 0.001).
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 V, cross-sectional descriptive study.
食物力量量表（PFS）是一种衡量美味食物丰富的食物环境的享乐影响的工具。本研究的目的是在大量成年人群中验证土耳其语版 PFS（PFS-Tr）。
数据来自 505 名年龄在 19 至 64 岁之间的土耳其成年人。所有参与者都完成了 PFS-Tr 和荷兰饮食行为问卷（DEBQ）。
与原始的英语版 PFS 相比，PFS-Tr 中的项目 5 和 13 在可获得食物因子下显示出最高的误差协方差。为了提供一般标准，删除了这两个项目。删除这两个项目后，PFS-Tr 的克朗巴赫α系数为 0.922，“可获得食物”、“食物存在”和“食物味道”的克朗巴赫α值分别为 0.849、0.797 和 0.82。此外，DEBQ 的克朗巴赫α系数为 0.93。此外，还发现 BMI 与 PFS-Tr 的平均得分之间存在线性关联，模型拟合（R=0.02）和 PFS-Tr 与 DEBQ 呈正相关（r=0.497，p<0.001）。
这是第一个验证和报告 PFS 土耳其语版本的研究，我们的研究结果表明，PFS-Tr 是一种在土耳其成年人群中确定享乐性饥饿倾向的有效和可靠工具。
