The I³ Model is a meta-theoretical framework that posits intimate partner violence (IPV) perpetration is the product of three interactive factors: instigators, impellors, and inhibitors. The present study examined the effects of trait anger (an impellor), psychological flexibility (a disimpellor), and alcohol intoxication (a disinhibitor) on IPV perpetration. Participants were 249 heavy drinkers (41% female) who had perpetrated IPV toward their current partner in the past year. Participants completed self-report measures of trait anger and psychological flexibility, were randomly assigned to consume an alcoholic or non-alcoholic beverage, and then engaged in the Taylor Aggression Paradigm (Taylor, 1967) ostensibly against their current partner. Analyses detected a small-to-medium effect for two separate two-way interactions. First, a significant Beverage x Psychological Flexibility interaction was detected. Consistent with the I³ Model, explication analyses revealed that alcohol intoxication predicted higher levels of IPV perpetration in those who reported low, but not high, psychological flexibility (i.e., low disimpellance). Second, although the Beverage x Trait Anger interaction was non-significant, explication analyses revealed that alcohol intoxication predicted higher levels of IPV perpetration among those who reported low, but not high, trait anger (i.e., low impellance). These results have several potential treatment implications among alcohol-consuming clients.

我³模型是一个元理论框架，它假定亲密伴侣暴力 (IPV) 的实施是三个交互因素的产物：煽动者、推动者和抑制者。本研究检查了特质愤怒（推动因素）、心理灵活性（消除推动因素）和酒精中毒（消除抑制因素）对 IPV 实施的影响。参与者是 249 名酗酒者（41% 是女性），他们在过去一年中对他们目前的伴侣实施了 IPV。参与者完成了对愤怒特质和心理灵活性的自我报告测量，被随机分配饮用酒精或非酒精饮料，然后表面上与他们当前的伴侣进行泰勒侵略范式（Taylor，1967）。分析检测到两个独立的双向相互作用的中小影响。第一的，检测到显着的饮料 x 心理灵活性相互作用。与我一致³模型，解释分析表明，酒精中毒预示着那些报告心理灵活性低但不高的人（即低失望）的 IPV 实施水平更高。其次，尽管饮料 x 特质愤怒的交互作用不显着，但解释性分析表明，酒精中毒预示着报告低但不高的特质愤怒（即低冲动）的人的 IPV 实施水平更高。这些结果对酗酒的客户有几个潜在的治疗意义。
