Acute stress disorder (ASD) was introduced into the DSM-IV to recognize early traumatic responses and as a precursor of PTSD. Although the diagnostic criteria for ASD were altered and structured more similarly to the PTSD definition in DSM-5, only the PTSD diagnosis includes a dissociative subtype. Emerging research has indicated that there also appears to be a highly symptomatic subtype for ASD. However, the specific nature of the subtype is currently unclear. The present study investigates the possible presence of ASD subtypes in a mixed sample of victims meeting caseness for DSM-5 ASD based on self-report following four different types of traumatic exposure (N=472). The results of latent profile analysis revealed a 5-class solution. The highly symptomatic class was marked by high endorsement on avoidance and dissociation compared to the other classes. Findings are discussed in regard to its clinical implications including the implications for the pending the ICD-11 and the recently released DSM-5.
急性应激障碍（ASD）被纳入 DSM-IV 以识别早期创伤反应，并作为 PTSD 的前兆。尽管 ASD 的诊断标准有所改变，并与 DSM-5 中 PTSD 的定义更为相似，但只有 PTSD 诊断包括分离亚型。新兴研究表明，ASD 似乎也存在一种高度症状亚型。然而，该亚型的具体性质目前尚不清楚。本研究在一个混合样本中调查了 DSM-5 ASD 的病例，该样本基于四种不同类型的创伤暴露（N=472）的自我报告，研究 ASD 亚型的可能存在。潜在剖面分析的结果显示了 5 种类型的解决方案。与其他类型相比，高度症状类在回避和分离方面的高认可度很高。研究结果讨论了其临床意义，包括对即将到来的 ICD-11 和最近发布的 DSM-5 的影响。
