ulgation of preliminary criteria for binge-eating disorder  in Appendix B of DSM-IV
documented the clinical utility and validity of binge-eating disorder. The only significant dif-
ference from the prelimin ary criteria is that the minimum average frequency of binge eating re-
quired for diagnosis is once weekly over the la st 3 months, identical to the frequency criterion
for bulimia nervosa (rather than at least 2 days a week for 6 months in DSM-IV).
