Adolescence and emerging adulthood represent a period of heightened vulnerability to sexual violence (SV). While some research suggests that exposure to sexually explicit material (SEM) among adolescents and college students is associated with sexually violent behavior, our understanding of this relationship is limited. This study aimed to assess the relationship between prior exposure to several types of SEM and sexually violent behavior in a sample of first-year university men in Vietnam.
A cohort of 739 first-year male university students completed three survey waves over 14 months, providing information on contact and non-contact sexually violent behavior, exposure to SEM, and other theorized confounders of the SEM-SV relationship. Controlling for these covariates, we estimated the average treatment effect of SEM on contact and non-contact SV using the propensity score method. We also conducted a dose-response analysis for the effect of violent SEM on SV based on frequency-of-exposure classes derived from latent class analysis. The majority of the sample reported exposure to SEM in the prior six months, with 41% of the sample reporting exposure to violent SEM. In propensity-adjusted models, exposure to violent SEM, but not other types, had a small but significant positive effect on contact and non-contact SV. These effects increased for frequent viewers of violent SEM. Models of contact SV showed endogeneity, warranting caution.
Exposure to violent SEM is prevalent among university men in Vietnam and may be contributing to sexually violent behavior. Incorporating media literacy into SV prevention programs to mitigate these potential effects may be warranted.
青少年和刚成年的阶段是性暴力（SV）高发脆弱期。尽管一些研究表明，青少年和大学生接触色情材料（SEM）与性暴力行为有关，但我们对这种关系的理解是有限的。本研究旨在评估越南大一男性大学生样本中，先前接触几种类型 SEM 与性暴力行为之间的关系。
一个由 739 名大一男性大学生组成的队列在 14 个月内完成了三波调查，提供了有关接触和非接触性暴力行为、SEM 暴露以及 SEM-SV 关系的其他潜在混杂因素的信息。在控制这些协变量的情况下，我们使用倾向评分法估计 SEM 对接触和非接触性 SV 的平均处理效应。我们还根据潜在类别分析得出的暴露频率类别，对暴力 SEM 对 SV 的影响进行了剂量反应分析。大多数样本报告在过去六个月内接触过 SEM，其中 41%的样本报告接触过暴力 SEM。在倾向调整模型中，接触暴力 SEM，而不是其他类型，对接触和非接触性 SV 有一个小但显著的正向影响。对于经常观看暴力 SEM 的人来说，这些影响会增加。接触性 SV 的模型存在内生性，需要谨慎对待。
越南大学生中普遍存在接触暴力 SEM 的情况，这可能导致性暴力行为。将媒体素养纳入 SV 预防计划，以减轻这些潜在影响可能是有必要的。
