目的：暴露于多重创伤事件(多受害者)是青少年有害健康结局和危险行为的可靠预测因子。目前的研究扩展了关于青少年创伤暴露的流行率和后果的文献，方法是：(A)在一个大的、种族多样的、多地点的青少年临床样本中经验地识别和描述创伤暴露概况，以及(B)评估所确定的概况与人口统计特征和临床相关性之间的关系。方法：使用国家儿童创伤应激网络核心数据集的数据，利用潜在类别分析，在3485名青少年(年龄13-18岁，63%女性，35.7%白人，23.2%黑人/非裔美国人，35.0%西班牙裔/拉丁裔)中识别和描述受害特征。心理痛苦和危险行为的多项测量被评估为创伤暴露类别的协变量。结果：确定了五个创伤暴露类别或概况。四个类别--约占样本的一半--具有多受害者的特征。多受害者类别根据创伤类型的数量、是否发生情绪虐待以及情绪虐待是否发生在单一或多个发展阶段来区分。与人口统计特征和心理健康结果的独特关系被观察到。讨论：结果表明，多受害者不是一种单一的现象，而是一组不同的创伤暴露经历，在年轻人中具有独特的相关性。有必要进一步研究多受害者的预防以及将慢性创伤暴露、性别和种族与负面结果联系起来的机制。
Objective: Exposure to multiple traumatic events (polyvictimization) is a reliable predictor of deleterious health outcomes and risk behaviors in adolescence. The current study extends the literature on the prevalence and consequences of adolescent trauma exposure by (a) empirically identifying and characterizing trauma exposure profiles in a large, ethnically diverse, multisite, clinical sample of adolescents, and (b) evaluating relations among identified profiles with demographic characteristics and clinical correlates. Method: Data from the National Child Traumatic Stress Network Core Data Set were used to identify and characterize victimization profiles using latent class analysis in a sample of 3,485 adolescents (ages 13-18, 63% female, 35.7% White, 23.2% Black/African American, 35.0% Hispanic/Latino). Multiple measures of psychological distress and risk behaviors were evaluated as covariates of trauma exposure classes. Results: Five trauma exposure classes, or profiles, were identified. Four classes-representing approximately half the sample-were characterized by polyvictimization. Polyvictimization classes were differentiated on number of trauma types, whether emotional abuse occurred, and whether emotional abuse occurred over single or multiple developmental epochs. Unique relations with demographic characteristics and mental health outcomes were observed. Discussion: Results suggest polyvictimization is not a unidimensional phenomenon but a diverse set of trauma exposure experiences with unique correlates among youth. Further research on prevention of polyvictimization and mechanisms linking chronic trauma exposure, gender, and ethnicity to negative outcomes is warranted.
