First responders, including firefighters and emergency medical technicians (EMTs), are under extreme stress from repeated exposure to potentially traumatic events. To optimize treatment for this population, it is critical to understand how the various posttraumatic stress disorder (PTSD) symptom factors are associated with one another so these relations may be targeted in treatment.
Using a sample of treatment-seeking firefighters/EMTs (N = 342), we conducted a partial correlation network analysis of the eight-factor model. A Bayesian directed acyclic graph (DAG) was used to estimate causal associations between clusters.
Approximately 37 % of the sample screened positive for probable PTSD. Internal re-experiencing and external re-experiencing had the strongest edges. In the DAG, internal re-experiencing was the parent node and was potentially predictive of external re-experiencing, negative affect, dysphoric arousal, and avoidance.
Data were drawn from a treatment-seeking sample that may not generalize to all firefighters/EMTs.
The current findings are consistent with prior research suggesting re-experiencing plays a critical role in developing and maintaining PTSD symptoms. Future research should investigate non-treatment-seeking first responders, as well as EMTs and firefighters as individual populations.
急救人员，包括消防员和急救医疗技术员（EMTs），由于反复接触潜在创伤性事件而承受着巨大的压力。为了优化对这一人群的治疗，了解各种创伤后应激障碍（PTSD）症状因素之间的相互关系至关重要，以便在治疗中针对这些关系。
我们使用寻求治疗的消防员/EMTs 样本（N=342），对八因素模型进行了部分相关网络分析。贝叶斯有向无环图（DAG）用于估计簇之间的因果关系。
大约 37%的样本筛查出可能患有 PTSD。内部再体验和外部再体验具有最强的关联。在 DAG 中，内部再体验是父节点，可能预测外部再体验、负性情绪、烦躁性唤醒和回避。
数据来自于寻求治疗的样本，可能无法推广到所有消防员/EMTs。
目前的研究结果与先前的研究一致，表明再体验在 PTSD 症状的发展和维持中起着关键作用。未来的研究应调查非寻求治疗的急救人员，以及 EMTs 和消防员作为单独的人群。
