Abstract
Although negative emotionality (NE) and negative urgency (NU) are risk factors for binge eating, it is unknown how these traits may interact to increase risk for clinical levels of binge eating. We examined a model of cross-sectional associations among levels of NE, NU, and eating disorder psychopathology (i.e., eating, shape, and weight concerns, and restraint) in a community sample of 68 women with binge-eating disorder or bulimia nervosa and 75 control women with no eating disorder history. Participants completed semi-structured diagnostic interviews and self-report questionnaires measuring NE, NU, eating disorder psychopathology, and anxiety and depression symptoms. After controlling for anxiety and depression symptoms and body mass index, women with binge eating reported higher levels of negative urgency and eating disorder psychopathology than control women with no history of eating disorders, whereas there was no difference in levels of negative emotionality between the two groups. There was an indirect effect of negative emotionality on eating disorder psychopathology via negative urgency. Group membership did not moderate this association. Our findings support a model in which a tendency toward negative emotionality, coupled with a tendency to engage in rash action when experiencing negative emotions, is associated with eating disorder psychopathology in women with and without eating disorders characterized by binge eating.
