This study used an experimental paradigm to investigate the roles of sexual victimization history and alcohol intoxication in young women's sexual-emotional responding and sexual risk taking. A nonclinical community sample of 436 young women, with both an instance of heavy episodic drinking and some HIV/STI risk exposure in the past year, completed childhood sexual abuse (CSA) and adolescent/adult sexual assault (ASA) measures. A majority of them reported CSA and/or ASA, including rape and attempted rape. After random assignment to a high alcohol dose (.10 %) or control condition, participants read and projected themselves into an eroticized scenario of a sexual encounter involving a new partner. As the story protagonist, each participant rated her positive mood and her sexual arousal, sensation, and desire, and then indicated her likelihood of engaging in unprotected sex. Structural equation modeling analyses revealed that ASA and alcohol were directly associated with heightened risk taking, and alcohol's effects were partially mediated by positive mood and sexual desire. ASA was associated with attenuated sexual-emotional responding and resulted in diminished risk taking via this suppression. These are the first findings indicating that, compared to non-victimized counterparts, sexually victimized women respond differently in alcohol-involved sexual encounters in terms of sexual-emotional responding and risk-taking intentions. Implications include assessing victimization history and drinking among women seeking treatment for either concern, particularly women at risk for HIV, and alerting them to ways their histories and behavior may combine to exacerbate their sexual risks.
本研究采用实验范式，调查了性受害史和酒精中毒对年轻女性性情感反应和性风险行为的作用。一个非临床的社区样本包括 436 名年轻女性，她们都有过重度间歇性饮酒和过去一年中存在 HIV/性传播感染（STI）风险暴露的经历，完成了童年性虐待（CSA）和青少年/成年性侵犯（ASA）的测量。她们中的大多数人报告了 CSA 和/或 ASA，包括强奸和强奸未遂。在随机分配到高酒精剂量（0.10%）或对照条件后，参与者阅读并将自己投射到一个涉及新伴侣的性接触的色情化场景中。作为故事主角，每位参与者都对自己的积极情绪和性唤起、感觉和欲望进行了评分，然后表明自己发生无保护性行为的可能性。结构方程模型分析表明，ASA 和酒精与更高的风险行为直接相关，而酒精的作用部分通过积极情绪和性欲望来介导。ASA 与性情感反应减弱有关，通过这种抑制作用导致风险行为减少。这些是第一个发现，表明与未受害的对照组相比，性受虐的女性在涉及酒精的性接触中，在性情感反应和冒险意图方面的反应不同。这意味着，对于寻求治疗的女性，无论是治疗酒精问题还是性问题，都应该评估其受害史和饮酒情况，特别是对于那些面临 HIV 风险的女性，并提醒她们了解自己的历史和行为可能会如何结合，从而加剧她们的性风险。
