摘要

目的:暴饮暴食似乎与冲动有关,尤其是对负面情绪的反应(即负面紧迫感)。然而,负面紧迫感通常是通过自我报告来评估的,这种方法只能捕捉到紧迫感的某些方面,而且可能存在偏差。很少有研究对暴饮暴食样本进行实验性情感操作后的冲动性进行研究:在本研究中,经常暴饮暴食的人在高热量和低热量食物刺激下分别完成了一次负面情绪诱导和一次中性情绪诱导后的行为冲动(去/不去)任务:结果:在消极(而非中性)情绪状态下,对高热量食物线索的行为冲动性越大,暴饮暴食行为越频繁。此外,在控制自我报告的负面紧迫感的情况下,这种负面紧迫感的行为测量方法独特地解释了暴饮暴食频率的差异,这表明行为测量方法可能是对自我报告测量方法的有益补充:这些研究结果为负性紧迫感与暴饮暴食之间的关系提供了新颖且令人信服的证据,突出表明负性紧迫感可能是一个重要的干预目标。

Behaviourally assessed negative urgency is uniquely associated with binge-eating frequency

Objective

Binge eating appears to be associated with impulsivity, especially in response to negative affect (i.e., negative urgency). However, negative urgency is typically assessed via self-report, which captures only some aspects of urgency and may be subject to bias. Few studies have examined impulsivity following experimental manipulations of affect in binge-eating samples.

Method

In the present study, individuals who engage in regular binge eating completed a behavioural impulsivity (go/no-go) task with high- and low-calorie food stimuli, once following negative affect induction and once following neutral affect induction.

Results

Greater behavioural impulsivity to high-calorie food cues while in a negative (and not a neutral) affective state was associated with more frequent binge-eating behaviour. Further, this behavioural measure of negative urgency uniquely accounted for variance in binge-eating frequency when controlling for self-reported negative urgency, suggesting that behavioural measures may be a useful complement to self-report measures.

Discussion

These findings provide novel and compelling evidence for the relationship between negative urgency and binge eating, highlighting negative urgency as a potentially important target for intervention.

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.
