坊间和相关证据表明，社会排斥和酒精依赖之间存在联系。此外，最近的一项功能磁共振研究发现，与健康对照组相比，酒精依赖者与排斥行为相关的神经相关因素存在差异。我们预测，强烈饮酒将减少社会排斥的负面影响。酒精(0.4g/kg)或匹配的安慰剂以随机、双盲、交叉设计的方式，在两个疗程中对32名危险饮酒者进行了抽样。在每一次训练中，参与者都会通过电脑传球游戏“Cyberball”接触到排斥事件。为了量化排斥的影响，在每一次测试期间填写了两次基本需要问卷；紧接在(一)社会包容和(二)社会排斥之后。排斥导致了基本需求问卷得分的强劲变化，这与之前的文献一致。酒精摄入不影响模拟社会排斥的效果，这一结果得到了贝叶斯分析的支持。探索性分析显示，年龄和排斥之间的负面关系在两次会议上都引发了基本需求威胁。总而言之，中等剂量的酒精不会影响危险饮酒者的模拟社会排斥体验。需要进一步的研究来确定酒精管理对使用不同剂量和不同酒精使用者的人群的社会排斥的影响。
Anecdotal and correlational evidence suggests a relationship between social ostracism and alcohol dependence. Furthermore, a recent fMRI investigation found differences in the neural correlates associated with ostracism in people with alcohol dependence compared to healthy controls. We predicted that acutely administered alcohol would reduce the negative effects of social ostracism. Alcohol (0.4 g/kg) or matched placebo was administered to a sample of 32 hazardous drinkers over two sessions in a randomized, double-blind, cross over design. In each session, participants were exposed to an ostracism event via the computerized ball passing game, "Cyberball." In order to quantify the effects of ostracism, the fundamental needs questionnaire was completed twice on each testing session; immediately after (i) social inclusion and (ii) social exclusion. Ostracism caused robust changes to scores on the fundamental needs questionnaire, in line with previous literature. Alcohol administration did not influence the effects of simulated social ostracism, which was supported by a Bayesian analysis. Exploratory analyses revealed a negative relationship between age and ostracism induced fundamental needs threat across both sessions. In conclusion, a moderate dose of alcohol did not influence experience of simulated social ostracism in hazardous drinkers. Further research is needed to establish the effects of alcohol administration on social ostracism using different doses and populations of alcohol users.
