From the research article’s abstract: “Purpose Food addiction (FA) is related to greater body mass index (BMI), eating-disorder psychopathology, food craving, and psychosocial impairment. Less is known regarding the utility of the FA severity specifiers, as measured by the number of symptoms endorsed on the Yale Food Addiction Scale (YFAS 2.0). Methods Participants (N = 1854) were recruited from Amazon Mechanical Turk to complete an online survey on eating behaviors. Participants completed self-report measures assessing FA, eating-disorder psychopathology (Eating Disorder Examination Questionnaire), and food craving (Food Craving Inventory). Based on the YFAS 2.0 specifiers, participants were classified into four FA groups: No FA (n = 1643), mild (n = 40), moderate (n = 55), and severe (n = 116).
