Negative urgency (NU) moderated the temporal relationship of negative affect to binges, such that women with lower scores on NU experienced a sharper increase in affect prior to binges. Individual differences in eating expectancies also moderated the relationship of affect to binge eating. Results suggest that women with high levels of NU and expectancy endorsement are triggered to binge by smaller shifts in negative affect than women who do not endorse these traits.
