*3.3. Frequency of YFAS Criteria*

Regarding the whole sample, the most prevalent criteria were (i) clinically significant impairment or distress in relation to food (90.8%); (ii) craving (79.2%); and (iii) persistent desire or repeated unsuccessful attempts to cut down (78.5%). Table 4 shows the percentage of each YFAS criterion met in the total sample, as well as for each type of ED. "Clinically significant impairment or distress in relation to food" was one of the most prevalent diagnostic criteria regardless of the type of ED, but each type of ED was associated with specific criteria: "Use in physically hazardous situations" with ED associated with under- or overweight, "craving" with ED characterized by recurrent episodes of binge eating.



\* Criteria that are present only in the second version of the YFAS (modeled on DSM-5 criteria), assessed in only 77 ED patients, 23 AN-R patients, 16 AN-BP patients, 33 BN patients, and 4 BED patients. %: percentage; AN-BP: anorexia nervosa binge-eating/purging type; AN-R: anorexia nervosa restricting type; BED: binge-eating disorder; BN: bulimia nervosa; ED: eating disorder; YFAS: Yale Food Addiction Scale.
