Abstract summary 

Food addiction (FA) is linked to eating disorders and obesity. The Yale Food Addiction Scale (YFAS), which has various versions in different languages, is widely used to assess FA worldwide. This meta-analysis aimed to assess the YFAS through reliability generalization meta-analysis (REGEMA). From their inception until April 2024, a comprehensive systematic review across more than 30 databases was conducted to identify studies reporting reliability measures (e.g., Cronbach's alpha and McDonald's omega) of the YFAS. Sixty-five studies were included in this meta-analysis, with a median sample size of 451 participants. The results of the random-effects meta-analysis showed a high pooled reliability coefficient (α = 0.85, 95% CI: 0.83 to 0.86 p < 0.001). Test-retest reliability was also estimated using a random-effects meta-analysis of 10 studies, resulting in a pooled test-retest correlation coefficient of intraclass coefficients of (ICC = 0.77, 95% CI: 0.70 to 0.84, p < 0.001). These findings highlight the consistency and robustness of the YFAS in detecting FA across studies, suggesting its reliability for screening for FA-related disordered eating.
