Abstract

Objective

Negative urgency (i.e., acting rashly when experiencing negative affect; NU), is a theorised maintenance factor in binge-eating type eating disorders. This study examined the association between trait NU and eating disorder severity, momentary changes in state NU surrounding episodes of binge eating, and the momentary mechanistic link between affect, rash action, and binge-eating risk.

Methods

Participants were 112 individuals with binge-eating disorder (BED). Baseline measures included the UPPS-P Impulsive Behaviour Scale to assess trait NU and the Eating Disorders Examination to assess binge-eating frequency and global eating disorder severity. Ecological momentary assessment captured real-time data on binge eating, negative affect, and state NU.

Results

Multiple regression analysis revealed a strong association between trait NU and eating disorder severity. Generalised estimating equations showed that state NU increased before and decreased after binge-eating episodes, and that this pattern was not moderated by trait-level NU. Finally, a multilevel structural equation model indicated that increases in rash action mediated the momentary relationship between states of high negative affect and episodes of binge eating.

Conclusion

These findings underscore the importance of both trait and state NU in binge-eating type eating disorders, and suggest NU as a potential key target for intervention.

研究暴食症患者的状态和特质紧迫性

目的负性紧迫感（即在经历负性情绪时贸然行动；NU）被认为是暴饮暴食型进食障碍的一个维持因素。本研究探讨了特质 NU 与进食障碍严重程度之间的关联、围绕暴饮暴食发作的 NU 状态的瞬间变化，以及情感、轻率行为和暴饮暴食风险之间的瞬间机制联系。基线测量包括用于评估特质NU的UPPS-P冲动行为量表和用于评估暴饮暴食频率和整体饮食失调严重程度的饮食失调检查。结果多重回归分析表明，特质NU与进食障碍严重程度之间存在密切联系。广义估计方程显示，状态 NU 在暴饮暴食发作前会增加，而在暴饮暴食发作后会减少，这种模式不受特质水平 NU 的调节。最后，一个多层次结构方程模型表明，轻率行为的增加介导了高负面情绪状态与暴饮暴食发作之间的瞬间关系。

期刊介绍： European Eating Disorders Review publishes authoritative and accessible articles, from all over the world, which review or report original research that has implications for the treatment and care of people with eating disorders, and articles which report innovations and experience in the clinical management of eating disorders. The journal focuses on implications for best practice in diagnosis and treatment. The journal also provides a forum for discussion of the causes and prevention of eating disorders, and related health policy. The aims of the journal are to offer a channel of communication between researchers, practitioners, administrators and policymakers who need to report and understand developments in the field of eating disorders.
