这项研究是我们旨在最好地描述儿童创伤后应激反应的研究的最新进展。在之前的一项研究中。我们比较了现有的创伤后应激障碍维度的病因学模型和经验模型，并确定了一个具有三个症状群(入侵/主动回避、麻木/被动回避和觉醒；Anthony，Lonigan和Hecht，1999)的分层模型。在这项研究中，我们在两个群体中交叉验证了这一模型。参与者是396名五年级学生，他们暴露在安德鲁飓风或雨果飓风中。多样本验证性因素分析表明，在经历了严重程度不同的创伤事件的人群中，该模型的阶乘不变性。这些结果表明，该模型对表征儿童创伤后应激反应具有较强的稳健性。对创伤后应激障碍的诊断、分类标准和经验性支持的理论的含义进行了讨论。
This study is the latest advancement of our research aimed at best characterizing children's posttraumatic stress reactions. In a previous study. we compared existing nosologic and empirical models of PTSD dimensionality and determined the superior model was a hierarchical one with three symptom clusters (Intrusion/Active Avoidance, Numbing/Passive Avoidance, and Arousal; Anthony, Lonigan, & Hecht, 1999). In this study, we cross-validate this model in two populations. Participants were 396 fifth graders who were exposed to either Hurricane Andrew or Hurricane Hugo. Multisample confirmatory factor analysis demonstrated the model's factorial invariance across populations who experienced traumatic events that differed in severity. These results show the model's robustness to characterize children's posttraumatic stress reactions. Implications for diagnosis, classification criteria, and an empirically supported theory of PTSD are discussed.
