The term 'hedonic hunger' refers to one's preoccupation with and desire to consume foods for the purposes of pleasure and in the absence of physical hunger. The Power of Food Scale (PFS) was developed as a quantitative measure of this construct in 2009. Since then, over 50 published studies have used the PFS to predict appetite-related outcomes including neural, cognitive, behavioural, anthropometric and clinical measures.
This narrative review evaluates how closely the PFS captures the construct it was originally presumed to assess and to more clearly define hedonic hunger itself.
The measure's relationship to four domains is reviewed and summarized: motivation to consume palatable foods; level of actual consumption of such foods; body mass; and subjective loss-of-control over one's eating behaviour. Findings are synthesized to generate a more accurate understanding of what the PFS measures and how it may relate to the broader definition of hedonic hunger.
Results suggest that the PFS is closely related to motivation to consume palatable foods and, in extreme cases, occurrence of loss-of-control eating episodes. PFS scores are not consistently predictive of amount of food consumed or body mass.
Implications of these findings are discussed in the context of behavioural health, and avenues for further inquiry are identified.
“享乐性饥饿”一词指的是一个人在没有身体饥饿的情况下，出于愉悦目的而专注于并渴望食用食物。食物力量量表（PFS）于2009年被开发出来，作为对这一概念的定量测量工具。从那时起，超过50项已发表的研究使用PFS来预测与食欲相关的结果，包括神经、认知、行为、人体测量和临床指标。
本叙述性综述评估PFS在多大程度上捕捉到了它最初假定要评估的概念，并更清晰地界定享乐性饥饿本身。
回顾并总结了该测量工具与四个领域的关系：食用美味食物的动机；此类食物的实际消费水平；体重；以及对自己饮食行为的主观失控感。综合研究结果，以更准确地理解PFS所测量的内容以及它与享乐性饥饿更广泛定义的关系。
结果表明，PFS与食用美味食物的动机密切相关，在极端情况下，与失控饮食发作的发生也密切相关。PFS得分并不能始终如一地预测食物摄入量或体重。
在行为健康的背景下讨论了这些发现的意义，并确定了进一步探究的途径。
