In this study, we examined the relationships between prior trauma, alexithymia, and sexual aggression perpetration among 610 U.S. college students and 107 college students from the Philippines utilizing a cross-sectional retrospective design. We tested a moderated mediation model with alexithymia as the mediator between prior trauma and sexual aggression perpetration, and alcohol use as a moderator of the alexithymia-sexual aggression link. Moreover, given that cultural norms may influence these relationships, we also examined the structural invariance of the proposed moderated mediation model. Path analyses and multiple group analysis were used to examine the moderated mediation model, and examine model differences between samples. We did not find evidence for alexithymia as a mediator, but there was a significant interaction between alcohol use severity and alexithymia on sexual aggression perpetration across both samples. Alexithymia is a key variable in understanding the alcohol use-sexual aggression perpetration relationship. Clinical implications and recommendations for future research are also discussed.

述情障碍、先前的创伤、酒精使用和性侵犯行为：适度调解模型的跨文化比较

在这项研究中，我们使用横断面回顾性设计检查了 610 名美国大学生和 107 名菲律宾大学生的既往创伤、述情障碍和性侵犯行为之间的关系。我们测试了一个调节调解模型，述情障碍作为先前创伤和性侵犯行为之间的中介，酒精使用作为述情障碍-性侵犯链接的调节因素。此外，鉴于文化规范可能会影响这些关系，我们还检查了所提出的调节中介模型的结构不变性。路径分析和多组分析用于检查调节中介模型，并检查样本之间的模型差异。我们没有找到述情障碍作为中介的证据，但在两个样本中，酒精使用严重程度和述情障碍对性侵犯行为之间存在显着的相互作用。述情障碍是理解酒精使用与性侵犯行为关系的关键变量。还讨论了对未来研究的临床意义和建议。
