Objective: The current study examined accuracy in estimating campus norms for eating disorder (ED) pathology and the impact of normative feedback on intentions to help friends. Participants: The sample included 130 undergraduate women. Method: Participants estimated prevalence of ED pathology and were randomly assigned to normative feedback or a control condition. Vignettes were presented describing bulimic and sleep disorder symptoms. After presentation of each vignette, participants reported sympathy for and intentions to help friends with similar symptoms. Results: Nine ED pathology estimates were significantly higher than comparison values documented in a larger survey of women attending their university in the previous year. Those who received normative feedback reported lower intentions to help and lower sympathy for a student with bulimic symptoms compared to sleep disorder symptoms. Conclusion: Results raise the possibility that normative feedback could reduce support for friends with bulimic symptoms.
