The latent structure of posttraumatic stress disorder (PTSD) has been widely discussed, with the majority of studies in this area being conducted in the US. The current study aimed to extend this area of research by comparing seven existing PTSD factor models in a sample of 754 trauma-exposed university students from Slovakia, where similar research has not been conducted yet. The sample was predominantly female (83.69%), with a mean age of 22.68 years. The comparison of competing models revealed that the Anhedonia model, consisting of six inter-correlated factors of reexperiencing, avoidance, negative affect, anhedonia, dysphoric arousal and anxious arousal, provided the best fit. Several factors of the Anhedonia model also showed differential relationships with the external variables of anxiety and depression. The study contributes to the limited literature on the latent structure of PTSD in Eastern Europe.
创伤后应激障碍（PTSD）的潜在结构已被广泛讨论，该领域的大多数研究都是在美国进行的。本研究旨在通过比较来自斯洛伐克的 754 名创伤暴露的大学生样本中现有的七个 PTSD 因素模型，来扩展这一研究领域，因为在斯洛伐克还没有进行过类似的研究。该样本主要为女性（83.69%），平均年龄为 22.68 岁。对竞争模型的比较表明，由再体验、回避、负性情绪、快感缺失、烦躁觉醒和焦虑觉醒六个相互关联的因素组成的快感缺失模型提供了最佳拟合。快感缺失模型的几个因素也与焦虑和抑郁等外部变量显示出不同的关系。该研究为东欧 PTSD 潜在结构的有限文献做出了贡献。
