Exposure to traumatic events has been implicated in the onset and development of a range of psychiatric disorders. People can be exposed to multiple traumatic events and previous research suggests that traumatic experiences may cluster at the individual level.
This study aimed to examine the distribution of traumatic experiences in a large nationally representative sample using latent class analysis, and estimate the relationship between these classes and a number of demographic and clinical variables. Data from the National Comorbidity Survey was used.
Four latent classes, each representative of a range of traumatic experiences were identified. The classes were labelled 'high risk' (class 1), 'exposure to non-sexual adult interpersonal/non-interpersonal trauma' (class 2), 'intermediate risk/sexual abuse' (class 3), and 'low risk' (class 4). Each of the latent classes was predicted by several of the demographic variables. In addition, membership of classes 1, 2, and 3 increased the risk of each of the clinical variables.
The findings have clinical implications for the assessment of trauma histories across a range of psychiatric diagnoses.
创伤事件的暴露与一系列精神障碍的发生和发展有关。人们可能会经历多种创伤事件，先前的研究表明，创伤经历可能在个体层面上聚集。
本研究旨在使用潜在类别分析检查大量全国代表性样本中的创伤经历分布，并估计这些类别与一些人口统计学和临床变量之间的关系。使用了来自全国共病调查的数据。
确定了四个潜在类别，每个类别代表一系列不同的创伤经历。这些类别分别被标记为“高风险”（类别 1）、“暴露于非性成人人际/非人际创伤”（类别 2）、“中等风险/性虐待”（类别 3）和“低风险”（类别 4）。每个潜在类别都被几个人口统计学变量预测。此外，类别 1、2 和 3 的成员身份增加了每个临床变量的风险。
这些发现对评估一系列精神诊断中的创伤史具有临床意义。
