Abstract

Objective:

In DSM‐IV, to be diagnosed with Bulimia Nervosa (BN) or the provisional diagnosis of Binge Eating Disorder (BED), an individual must experience episodes of binge eating is β€œat least twice a week” on average, for 3 or 6 months, respectively. The purpose of this review was to examine the validity and utility of the frequency criterion for BN and BED.

Method:

Published studies evaluating the frequency criterion were reviewed.

Results:

Our review found little evidence to support the validity or utility of the DSM‐IV frequency criterion of twice a week binge eating; however, the number of studies available for our review was limited.

Discussion:

A number of options are available for the frequency criterion in DSM‐V, and the optimal diagnostic threshold for binge eating remains to be determined. Β© 2009 American Psychiatric Association. Int J Eat Disord 2009
