The result s were as follows. first, negative affect, negative urgency, and eating expectancy correlate with binge eating behavior. Second, negative affect, negative urgency, and eating expectancy significantly predicts binge eating behavior. Third, negative affect influence binge eating behavior by interacting with negative urgency and eating expectancy respectively. That is, negative affect, negative urgency, and eating expectancy showed two-way interaction in predicting binge eating behavior. Fourth, negative affect, negative urgency, eating expectancy showed three-way interaction in predicting binge eating behavior. Specifically, the higher the levels of eating expectancy were, the much more interacting effect of negative urgency on the relationship between negative affect and binge eating behavior has increased. Finally, the findings were discussed and limitations of this study and suggestions for future study were addressed.
