背景：创伤应激症状在持续威胁和创伤暴露的情况下是如何展开的，人们对此知之甚少。本研究旨在识别冲突中的创伤应激症状轨迹，以及潜在的危险因素。方法：采用体验抽样的方法，对100名遭受火箭弹袭击的以色列平民在2014年以色列-加沙冲突期间的创伤应激症状进行研究。30天内每天两次通过手机进行创伤症状的总结报告。结果：潜在班级增长分析显示，冲突期间创伤应激症状的发展轨迹有四个不同的类别(低、低、中、高)。女性、没有恋爱关系和较高的创伤暴露是潜在的危险因素。限制：在冲突的早期阶段没有收集数据，样本相对较少，只调查创伤应激症状作为结果。结论：本研究确定了冲突期间平民中不同的创伤应激症状轨迹，不同的亚组随着时间的推移表现出不同的反应模式，与各种危险因素相关。调查对持续创伤的反应，并确定不同应激症状轨迹的预测因子，对于有针对性地提供干预措施具有临床意义。对不同轨迹的进一步探索可能会阐明推动复原力和恢复的机制，包括在持续暴露的情况下，例如在冲突期间。
Background: The ways in which traumatic stress symptoms unfold under situations of ongoing threat and trauma exposure are poorly understood. The current study aims to identify traumatic stress symptom trajectories during conflict, as well as potential risk factors.Methods: Experience sampling methods were used to study traumatic stress symptoms during the 2014 Israel-Gaza conflict in 100 Israeli civilians exposed to rocket fire. Summary reports of traumatic symptoms were made twice-daily for 30 days via mobile phone.Results: Latent class growth analysis revealed four distinct classes (low, reducing, moderate, and high) characterised by their trajectory of traumatic stress symptoms during the conflict. Female gender, not being in a relationship, and higher prior trauma exposure were identified as potential risk factors.Limitations: Data were not collected in the early phase of the conflict, the sample was relatively small, and only traumatic stress symptoms were investigated as outcomes.Conclusions: This study identified heterogeneous traumatic stress symptom trajectories among civilians during a conflict, with different subgroups showing distinct response patterns over time, associated with various risk factors. Investigating responses to ongoing trauma, and identifying predictors of different stress symptom trajectories has clinical implications for the targeted delivery of interventions. Further exploration of heterogeneous trajectories could potentially elucidate mechanisms that drive resilience and recovery, including in situations of ongoing exposure such as during conflict.
