From the research article’s abstract: “Purpose: Previous studies have demonstrated overlapping behavioral features between substance-use disorders and food addiction, the latter of which is particularly prevalent among individuals with overweight or obesity. However, the unique attributes of food addiction as a possible phenotype within overweight and obesity are not fully understood. Methods: This cross-sectional study recruited participants (n = 46) with overweight or obesity, nearly half (n = 20) of whom met the criteria for food addiction based on the Yale Food Addiction Scale 2.0 (YFAS 2.0) and examined responses to self-report questionnaires that indexed behavioral characteristics relevant to addictive disorders. Results: Individuals with food addiction exhibited significantly higher scores on the Palatable Eating Motives Scale overall score (p < .001) and subscales for coping (p < .001) and enhancement (p < .001) of emotions, Dutch Eating Behavior Questionnaire Emotional Eating subscale (p < .001), UPPS-P Impulsivity Scale negative urgency (p < .001) and lack of perseverance (p = .01) subscales, and the Food Craving Inventory overall score (p = .02) and subscales of cravings for sweets (p < .01) and fast food fats (p = .02).
