BACKGROUND: The Yale Food Addiction Scale (YFAS) was developed in 2009 to assess food addiction (FA); a revised version was released in 2016 (YFAS 2.0). The objective of this study was to determine the statistical and clinical validity of the YFAS 2.0 in adults seeking bariatric surgery. METHODS: Patients who underwent a preoperative psychological evaluation in preparation for bariatric surgery from 2015 to 2018 were included. The YFAS 2.0 was administered as part of routine clinical care and validated against an assessment battery of standardized clinical measures. Statistical analyses included chi-square and Wilcoxon rank sum tests and calculation of Spearman's rank correlation coefficients. RESULTS: Overall, 1061 patients were included. Mean age and BMI were 47.5 ± 12.9 years and 46.9 ± 13.4 kg/m2, respectively. There were 196 (18%) patients who screened positive on the YFAS 2.0 (21% mild, 23% moderate, and 56% severe FA). The YFAS 2.0 demonstrated strong convergent validity where patients who met criteria for FA had significantly increased levels of binge eating (p < 0.001), emotional eating (p < 0.001), and lower self-efficacy (p < 0.001). Discriminant validity was demonstrated by lack of association with alcohol use (p = 0.319). The YFAS 2.0 was significantly correlated with total scores for depression (p < 0.001), anxiety (p < 0.001), bipolar disorder symptoms (p < 0.001), and trauma history (p < 0.001). CONCLUSIONS: The prevalence of FA in a large sample of patients seeking bariatric surgery was consistent with previous literature. These data suggest that the YFAS 2.0 is psychometrically valid, demonstrating strong construct validity, and is a clinically useful measure of FA severity in patients pursuing bariatric surgery.
