Confirmatory factor analysis and gender invariance of Persian version of the modified Yale food addiction scale (mPYFAS) 2.0: insight from a large scale Iranian sample

In this study, researchers developed a Persian version of the Modified Yale Food Addiction Scale 2.0 (mYFAS 2.0) to assess food addiction in Persian-speaking individuals. They translated and tested the scale's reliability and validity through an online survey with 9606 Persian speaking participants. The results showed that the Persian mYFAS 2.0 performed well, with a reliable single-factor model. The internal consistency and reliability were good across the entire sample and in both male and female groups. The relationships between mYFAS 2.0 and other scales measuring binge eating, impulsivity, and resilience were significant. The findings suggest that the Persian version of mYFAS 2.0 is a reliable tool for assessing food addiction in the Persian-speaking population. The study used statistical analyses like confirmatory factor analysis, indicating the scale's robustness. Overall, the psychometric properties of the Persian mYFAS 2.0 were satisfactory, providing a valuable instrument for researchers and healthcare professionals studying and addressing food addiction in this population. The study contributes to cross-cultural research and enhances our understanding of food addiction in diverse linguistic communities.
