Abstract
PURPOSE: The present study was performed to develop the Persian version of Power of Food Scale (PFS) questionnaire (PFS-P) and to assess the hedonic hunger in Iranian adult population. In addition, associations between individual differences, including sex and body mass index (BMI) and the appetitive motives measured by the PFS-P were assessed. METHODS: Eight hundred and twenty participants were studied. The PFS-P, the International Physical Activity Questionnaire, the Three-Factor Eating Questionnaire, and a questionnaire pertaining to demographic characteristics were completed for all participants. RESULTS: The Cronbach's alpha values for the factors "food available", "food present" and "food taste" were 0.87, 0.85, and 0.78, respectively. The intraclass correlation coefficient ranged from 0.80 to 0.97 for the factors of PFS-P. Good content, face, criterion, and construct validity were observed for the PFS-P. In addition, a good reliability was found for both aggregate score of the PFS-P and the scores of its three factors. Relatively strong associations were found between BMI and the PFS-P score (r = 0.43). The hedonic hunger was significantly higher in women than men (p < 0.001). CONCLUSIONS: The findings of the present study provide further evidence in support of the suitability of PFS as a valid instrument to measure hedonic hunger. PFS-P can be used as a valid and reliable measure to assess hedonic hunger in Iranian populations. In addition, a moderately strong correlation was observed between BMI and hedonic hunger scores. This study revealed that women may experience hedonic hunger more than men. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.
