The present study modeled the direct relationship between child sexual abuse (CSA) and adolescent peer-to-peer sexual victimization (APSV) and the mediated effect via variables representing the number of sexual partners, sexual risk behavior, and signaling sexual boundaries. A cross-sectional study on the effect of CSA on APSV was conducted, utilizing a multiple mediator model. Mediated and direct effects in the model were estimated employing Mplus using bootstrapped percentile based confidence intervals to test for significance of mediated effects. The study employed 327 Danish female adolescents with a mean age of 14.9 years (SD = 0.5). The estimates from the mediational model indicated full mediation of the effect of CSA on APSV via number of sexual partners and sexual risk behavior. The current study suggests that the link between CSA and APSV was mediated by sexual behaviors specifically pertaining to situations of social peer interaction, rather than directly on prior experiences of sexual victimization. The present study identifies a modifiable target area for intervention to reduce adolescent sexual revictimization.
本研究建立了儿童性虐待（CSA）与青少年同伴间性受害（APSV）之间的直接关系模型，并通过代表性伴侣数量、性风险行为和信号性边界的变量来检验中介效应。采用多中介模型对 CSA 对 APSV 的影响进行了横断面研究。使用 Mplus 基于 bootstrap 百分位置信区间估计模型中的中介和直接效应，以检验中介效应的显著性。该研究使用了 327 名丹麦女性青少年，平均年龄为 14.9 岁（SD=0.5）。中介模型的估计结果表明，性伴侣数量和性风险行为完全中介了 CSA 对 APSV 的影响。本研究表明，CSA 与 APSV 之间的联系是通过与社会同伴互动有关的性行为来介导的，而不是直接通过先前的性受害经历来介导。本研究确定了一个可干预的目标领域，以减少青少年的再次性受害。
