Abstract
The Power of Food Scale (PFS) was developed to assess hedonic hunger, or how individuals think and feel about food and eating in the absence of metabolic need. The measure was originally developed and validated in two adult samples, and recent preliminary support has been provided for the validity in a sample of preadolescents. The aim of the current study was to conduct a confirmatory factor analysis (CFA) on the PFS in a community sample of preadolescents and adolescents to examine the psychometric properties in youth. Participants were 148 youth ages 11–18 (M = 12.85) from two Midwestern communities in the United States. Participants completed the PFS to assess for hedonic hunger. Structural equation modeling was used to conduct multiple CFAs to test varying factor structures of the PFS in preadolescents and adolescents. Results suggested that the scale was best represented by the previously established 15-item version of the measure with an aggregate domain and three subscales based on food proximity (i.e., food available, food present, and food tasted). Results from the CFA revealed that the measurement model had a close fit (RMSEA = 0.033, CFI = 0.985). Cronbach’s α for the total scale and the three subscales ranged from 0.86 to 0.95. Findings suggest that the previously established factor structure of the 15-item PFS best represents the factor structure of the measure in a community sample of preadolescents and adolescents.
