The Power of Food Scale (PFS) is a 15-item self-report measure designed to measure the psychological impact and appetite for palatable foods in food-abundant environments, rather than actual food consumption.
It evaluates how the presence, availability, and tasting of food influence an individual’s motivation and desire to eat highly palatable foods.
PFS measures hedonic hunger or the drive to consume pleasurable foods.
It consists of three subscales: food available, food present, and food tasted.
Higher PFscores indicate greater responsiveness to food cues and environments.
It has good internal consistency and reliability.
Predicts overeating, binge eating, and weight-related outcomes.
Useful for understanding individual differences in susceptibility to the harmful food environment.
It quantifies the psychological influence of food cues on appetite and eating behavior, helping to identify those more vulnerable to overeating in environments rich with palatable foods.
