Theory and research suggest that posttraumatic stress disorder (PTSD) may mediate the relationship between child sexual abuse and adult sexual assault. However, little empirical research has examined the mediational role of PTSD. In the present study, the authors use structural equation modeling to examine the degree to which the three symptom clusters that define PTSD (reexperiencing, avoidance, and hyperarousal) contribute to sexual revictimization. To assess PTSD symptomatology, undergraduate women completed questionnaires (N = 1,449), which detailed the history and severity of childhood and adult sexual assault experiences. Results indicated that PTSD mediated sexual revictimization. When PTSD symptom clusters were examined individually, only the hyperarousal cluster was a significant mediator. Results are discussed in terms of information-processing mechanisms that may underlie sexual revictimization.
理论与研究表明，创伤后应激障碍（PTSD）可能在儿童期性虐待与成年期性侵犯之间的关系中起中介作用。然而，很少有实证研究考察PTSD的中介作用。在本研究中，作者使用结构方程模型来检验构成PTSD的三个症状群（重新体验、回避和过度警觉）对性再受害的影响程度。为了评估PTSD症状，本科女生完成了问卷调查（N = 1449），问卷详细记录了童年期和成年期性侵犯经历的历史和严重程度。结果表明，PTSD介导了性再受害。当单独考察PTSD症状群时，只有过度警觉群是一个显著的中介因素。研究结果从可能构成性再受害基础的信息加工机制方面进行了讨论。
