目前的精神疾病分类学将创伤后应激障碍（PTSD）描述为一个独立的诊断类别。然而，只有一项研究探讨了创伤后应激障碍的潜在结构，这项研究表明，创伤后应激障碍可能更准确地被概念化为对创伤性生活事件的极端反应，而不是一种离散的临床综合征。为了建立在现有的文献基础上，本研究探讨了潜在的结构创伤后应激反应，通过应用三个分类程序（MAXEIG，MAM-BAC和L-模式）收集的数据，从全国代表性的大样本的妇女（NS=2684和3033）和青少年（N=3775）。结果一致地提供了证据，跨样本和统计程序的维度PTSD解决方案。这些发现对创伤后应激反应的理论、评估和调查具有重要意义。
Current psychiatric nosology depicts posttraumatic stress disorder (PTSD) as a discrete diagnostic category. However, only one study has examined the latent structure of PTSD, and this study suggested that PTSD may be more accurately conceptualized as an extreme reaction to traumatic life events rather than a discrete clinical syndrome. To build on the existing literature base, the present research examined the latent structure of posttraumatic stress reactions by applying three taxometric procedures (MAXEIG, MAM-BAC, and L-Mode) to data collected from large nationally representative samples of women (ns=2684 and 3033) and adolescents (n=3775). Results consistently provided evidence for a dimensional PTSD solution across samples and statistical procedures. These findings have important implications for the theory, assessment, and investigation of posttraumatic stress reactions.
