From the research article’s abstract: “Aim: To assess the dimensionality and psychometric properties of an Italian version of the Yale Food Addiction Scale (YFAS) in a sample of obese/overweight patients attending low-energy diet therapy. Methods: Participants were 300 overweight and obese patients who were admitted to a private medical center in Rome, Italy. Controls were 300 (231 women and 69 men) adults from the general population. All of the participants were administered the YFAS and the binge eating scale (BES). Results: The one-factor model of the YFAS reported in previous studies did not fit the data [χ²₂₀₉ = 466.69, p < 0.001, root mean square error of approximation (RMSEA) = 0.07; 90 % CI: 0.06/0.08; comparative fit index (CFI) = 0.91; weighted root mean square residual (WRMR) = 1.40].
