负紧急性（即，对负面情绪做出反应时采取鲁莽行动的倾向）已经成为导致暴饮暴食的个体差异的重要人格特征。然而，缺乏研究调查遗传和/或环境影响在多大程度上构成了负面紧迫感对暴饮暴食的影响。此外，目前还不清楚负面的紧迫性暴食协会是否仅仅是由于负面情绪在暴食的发展/维持中的既定作用。目前的研究通过检查消极紧迫感、消极情绪和饮食失调之间的表型和病因学联系来解决这些差距（即，暴饮暴食，情绪化进食）在密歇根州双胞胎登记处的222对同性女性双胞胎样本中。即使在控制了负面情绪的影响之后，消极紧迫感也与饮食失调症状显著相关。遗传因素占大多数（62-77%）的这种表型关联，虽然这种遗传协变的显着比例是由于遗传影响共同的负面影响。非共享环境因素在关联中所占比例相对较小（23-38%），但这些非共享环境效应独立于负面影响。研究结果表明，基于情绪的轻率行为的存在，加上高水平的负面影响，可能会显着增加饮食失调的遗传风险。
Negative urgency (i.e., the tendency to engage in rash action in response to negative affect) has emerged as a critical personality trait contributing to individual differences in binge eating. However, studies investigating the extent to which genetic and/or environmental influences underlie the effects of negative urgency on binge eating are lacking. Moreover, it remains unclear whether negative urgency-binge eating associations are simply due to the well-established role of negative affect in the development/maintenance of binge eating. The current study addresses these gaps by examining phenotypic and etiologic associations between negative urgency, negative affect, and dysregulated eating (i.e., binge eating, emotional eating) in a sample of 222 same-sex female twin pairs from the Michigan State Twin Registry. Negative urgency was significantly associated with both dysregulated eating symptoms, even after controlling for the effects of negative affect. Genetic factors accounted for the majority (62–77%) of this phenotypic association, although a significant proportion of this genetic covariation was due to genetic influences in common with negative affect. Non-shared environmental factors accounted for a relatively smaller (23–38%) proportion of the association, but these non-shared environmental effects were independent of negative affect. Findings suggest that the presence of emotion-based rash action, combined with high levels of negative affect, may significantly increase genetic risk for dysregulated eating.
