Objective While most individuals with bulimia nervosa begin dieting prior to the onset of binge eating, some individuals begin binge eating prior to dieting. The purpose of this study was to assess the differences between these two groups. Methods Participants ( N = 120) in a treatment study for bulimia nervosa were separated into two groups (Binge First vs. Diet First) based on the ages they reported for the onset of binge eating and of dieting and then compared across a number of variables. Results Individuals in the Binge First group reported higher weight, higher shape and weight concern, lower age of onset of eating disorder symptoms, and an altered relationship of binge eating to vomiting when compared to individuals in the Diet First group. Discussion The differences between the two groups suggest that there may be subgroups of individuals with purging bulimia nervosa and that individuals in the Binge First group more closely resemble individuals with binge eating disorder than do those in the Diet First group. © 1999 by John Wiley & Sons, Inc.
