RED-9 = 9-item RED scale; BES = Binge Eating Scale; DEBQ-E = Dutch Eating Behavior Questionnaire – Emotional eating subscale; YFAS = Yale Food Addiction Scale: -Sum = Summed score, -SXS = Symptom count; TFEQ = Three Factor Eating Questionnaire: -R = Restraint, -D = Disinhibition, -H = Hunger; BMI-RES = Correlation residualized for Body Mass Index. BMI was log transformed and then residualized for age, education, race/ethnicity, income, and biological sex. Correlations or r = 0.19 or greater are statistically significant at p < 0.01; correlations of r = 0.15 or greater are statistically significant at p < 0.05.
