BACKGROUND/AIMS: Little is known about the association of binge drinking with impulsivity related to trait- or state-like aspects of behavior. The aim of the present study was therefore to investigate whether binge drinkers show an impairment of inhibitory control in comparison to non-binge drinkers when confronted with alcohol-associated or control stimuli, and whether this is reflected in self-reported impulsivity.
A go/no-go task with pictures of alcoholic and nonalcoholic beverages as well as control stimuli was administered to binge drinkers and a gender-matched group of non-binge drinkers. All participants also completed the Barratt Impulsiveness Scale (BIS-11).
We found an alcohol-specific impairment of response inhibition for binge drinkers only, while the groups did not differ with regard to overall response inhibition to the experimental stimuli or self-reported impulsiveness (BIS-11). In addition, the number of commission errors in response to alcohol-associated stimuli was the only significant predictor of binge drinking.
The findings of the present study suggest that when young adults have established binge drinking as a common drinking pattern, impairment of inhibition in response to alcoholic stimuli is the only significant predictor of binge drinking, but not general impulsive behavior.
背景/目的：关于暴饮与行为特质或状态方面的冲动性之间的关联，人们了解甚少。因此，本研究的目的是调查与非暴饮者相比，暴饮者在面对与酒精相关或对照刺激时是否表现出抑制控制受损，以及这是否反映在自我报告的冲动性上。
对暴饮者和性别匹配的非暴饮者组进行一项“是/否”任务，任务中呈现酒精饮料和非酒精饮料的图片以及对照刺激。所有参与者还完成了巴拉特冲动性量表（BIS-11）。
我们发现仅暴饮者存在针对酒精的反应抑制受损，而两组在对实验刺激的总体反应抑制或自我报告的冲动性（BIS-11）方面没有差异。此外，对与酒精相关刺激的错误反应次数是暴饮的唯一显著预测因素。
本研究结果表明，当年轻人将暴饮确立为一种常见饮酒模式时，对酒精刺激的抑制受损是暴饮的唯一显著预测因素，而非一般冲动行为。
