The I Model posits that men are more likely to engage in sexual aggression when instigation (e.g., their masculinity is threatened) and impellance are high (e.g., high trait anger) and inhibition is low (e.g., alcohol intoxication). This study investigates the independent and interactive effects of trait anger and acute intoxication on men's sexual aggression propensity after exposure to a masculinity threat.
Cisgender, heterosexual men ( = 120, ages 21-30) completed a self-report measure of trait anger, were randomly assigned to consume an alcoholic or nonalcoholic beverage, and engaged in the Sexual Imposition Paradigm (SIP), which assessed laboratory-based sexual aggression propensity toward a female confederate. Before the SIP, all men's masculinity was threatened via feedback from a personality test, which indicated that they were less masculine than other men.
The interaction between trait anger and beverage condition was significant. When men were intoxicated, sexual aggression propensity increased among men with higher trait anger, whereas for sober men, their sexual aggression propensity decreased with higher trait anger.
Consistent with the I Model, individual differences in trait anger may be an important risk factor for men's sexual aggression under the influence of alcohol. These findings have implications for intervention programming. Anger often arises as a response to feeling vulnerable, such as when men's masculinity is threatened. Thus, the integration of established, evidenced-based approaches to reduce feelings of anger into prevention programs for sexual aggression, particularly among men who have consumed alcohol, may be valuable.
I模型假定，当煽动因素（例如，其男子气概受到威胁）和冲动因素程度高（例如，特质愤怒程度高）且抑制因素程度低（例如，酒精中毒）时，男性更有可能实施性侵犯。本研究调查了特质愤怒和急性中毒对男性在面临男子气概威胁后的性侵犯倾向的独立影响和交互影响。
顺性别异性恋男性（n = 120，年龄21 - 30岁）完成了一项特质愤怒的自我报告测量，被随机分配饮用酒精饮料或非酒精饮料，并参与性侵犯范式（SIP），该范式评估了基于实验室的对女性同谋的性侵犯倾向。在SIP之前，通过一项人格测试的反馈对所有男性的男子气概进行了威胁，该测试表明他们比其他男性更缺乏男子气概。
特质愤怒与饮料条件之间的交互作用显著。当男性处于醉酒状态时，特质愤怒程度较高的男性的性侵犯倾向增加，而对于清醒的男性，其性侵犯倾向随着特质愤怒程度的升高而降低。
与I模型一致，特质愤怒的个体差异可能是男性在酒精影响下实施性侵犯的一个重要风险因素。这些发现对干预计划具有启示意义。愤怒常常是对感到脆弱的一种反应，比如当男性的男子气概受到威胁时。因此，将已确立的、基于证据的减少愤怒情绪的方法纳入性侵犯预防计划，特别是针对饮酒男性的计划，可能会有价值。
