The primary goal of this study was to determine the moderating effect of a history of heavy episodic drinking on the alcohol-aggression relation in men and women.
Participants were 310 (152 men and 158 women) healthy social drinkers between 21 and 35 years of age. Drinking history was operationalized as participants' average number of alcoholic drinks consumed per drinking occasion during the past year. Following the consumption of either an alcohol or a placebo beverage, participants were tested on a modified version of the Taylor Aggression Paradigm in which mild electric shocks were received from, and administered to, a fictitious opponent during a competitive task. Aggressive behavior was operationalized as the shock intensities administered to the fictitious opponent under conditions of low and high provocation.
Alcohol increased aggression only among highly provoked men who reported a history of heavy episodic drinking. A history of high-frequency drinking did not moderate the alcohol-aggression relation.
These findings highlight the importance of considering a history of heavy episodic drinking in the prediction of intoxicated aggression.
本研究的主要目的是确定大量偶发性饮酒史对男性和女性酒精与攻击行为关系的调节作用。
参与者为310名年龄在21至35岁之间的健康社交饮酒者（152名男性和158名女性）。饮酒史通过参与者在过去一年中每次饮酒场合平均饮用的酒精饮料数量来衡量。在饮用酒精饮料或安慰剂饮料后，参与者接受了泰勒攻击范式的修改版测试，即在一项竞争性任务中，他们会从一个虚构对手那里接受轻度电击，并向该对手施加电击。攻击行为通过在低挑衅和高挑衅条件下向虚构对手施加的电击强度来衡量。
酒精仅在报告有大量偶发性饮酒史且受到高度挑衅的男性中增加攻击行为。高频饮酒史并未调节酒精与攻击行为的关系。
这些发现凸显了在预测醉酒攻击行为时考虑大量偶发性饮酒史的重要性。
