This paper describes the psychometric evaluation of a new measure called the Power of Food Scale (PFS). The PFS assesses the psychological impact of living in food-abundant environments. It measures appetite for, rather than consumption of, palatable foods, at three levels of food proximity (food available, food present, and food tasted). Participants were 466 healthy college students. A confirmatory factor analysis replicated the three-factor solution found previously by Capelleri et al. [Capelleri, J. C., Bushmakin, A. G., Gerber, R. A., Leidy, N. K., Sexton, C., Karlsson, J., et al. (in press). Discovering the structure of the Power of Food Scale (PFS) in obese patients. International Journal of Obesity, 11, A165]. The PFS was found to have adequate internal consistency and test-retest reliability. The PFS and the Restraint Scale were regressed on four self-report measures of overeating. The PFS was independently related to all four whereas the Restraint Scale was independently related to two. Expert ratings of items suggested that the items are an acceptable reflection of the construct that the PFS is designed to capture. The PFS may be useful as a measure of the hedonic impact of food environments replete with highly palatable foods.
本文描述了一种名为食物力量量表（PFS）的新测量方法的心理测量学评估。PFS评估生活在食物丰富环境中的心理影响。它在食物接近的三个水平（可获得食物、呈现食物和品尝食物）上测量对美味食物的食欲，而非食物摄入量。参与者为466名健康大学生。验证性因素分析重现了Capelleri等人之前发现的三因素解决方案[Capelleri, J. C., Bushmakin, A. G., Gerber, R. A., Leidy, N. K., Sexton, C., Karlsson, J., et al.（即将发表）。发现肥胖患者食物力量量表（PFS）的结构。《国际肥胖杂志》，11，A165]。发现PFS具有足够的内部一致性和重测信度。将PFS和克制量表与四项暴饮暴食的自我报告测量指标进行回归分析。PFS与所有四项指标均独立相关，而克制量表仅与其中两项独立相关。对项目的专家评级表明，这些项目可以接受地反映了PFS旨在捕捉的结构。PFS作为衡量充斥着高度美味食物的食物环境的享乐影响的一种测量方法可能是有用的。
