As a diagnosis organized mainly on the basis of theoretical conceptualization, acute stress disorder (ASD) has been widely criticized for lack of empirical support since it was introduced into the DSM system. To address this issue, the present study investigated the latent structure of ASD symptoms measured by the Acute Stress Disorder Scale (ASDS). A total of 350 adults with a mean age of 32.9 years (SD = 14.0, range: 16-85) took part in this study 12 to 15 days after an earthquake. The results of confirmatory factor analyses showed that a five-factor intercorrelated model (dissociation, reexperiencing, avoidance, dysphoric arousal, and anxious arousal) demonstrated the best data fit. The findings provide preliminary empirical evidence in favor of a new reconceptualization of ASD symptoms, and are informative for the impending DSM-5.
作为一种主要基于理论概念化的诊断方法，急性应激障碍 (ASD) 自被引入 DSM 系统以来，因其缺乏实证支持而受到广泛批评。为了解决这个问题，本研究调查了由急性应激障碍量表 (ASDS) 测量的 ASD 症状的潜在结构。共有 350 名年龄在 32.9 岁（SD=14.0，范围：16-85）的成年人在地震后 12-15 天参加了这项研究。验证性因素分析的结果表明，一个五因素相互关联的模型（分离、再体验、回避、烦躁觉醒和焦虑觉醒）表现出了最好的数据拟合度。这些发现为 ASD 症状的新概念化提供了初步的经验证据，对即将出台的 DSM-5 也具有参考意义。
