The aim of this study was to determine if there are meaningful clusters of individuals with similar experiences of adverse life events in a nationally representative sample of Danish adolescents. Latent class analysis (LCA) was used to identify such clusters or latent classes. In addition, the relationships between the latent classes and living arrangements and diagnosis of post-traumatic stress disorder (PTSD) were estimated. A four-class solution was found to be the best description of multiple adverse life events, and the classes were labelled "Low Risk", "Intermediate Risk", "Pregnancy" and "High Risk". Compared with the Low Risk class, the other classes were found to be significantly more likely to have a diagnosis PTSD and live with only one parent. This paper demonstrated how trauma research can focus on the individual as the unit of analysis rather than traumatic events.
本研究的目的是确定在丹麦青少年具有全国代表性的样本中，是否存在经历过相似不良生活事件的有意义的个体集群。采用潜在类别分析（LCA）来识别此类集群或潜在类别。此外，还估计了潜在类别与生活安排以及创伤后应激障碍（PTSD）诊断之间的关系。发现四类解决方案是对多种不良生活事件的最佳描述，这些类别被标记为“低风险”、“中度风险”、“怀孕”和“高风险”。与低风险类别相比，发现其他类别被诊断为创伤后应激障碍且仅与一位家长生活在一起的可能性显著更高。本文展示了创伤研究如何能够以个体而非创伤事件作为分析单位。
