目的：考察压力感知与创伤后应激障碍症状之间的关系，以及焦虑的中介作用和领悟社会支持的调节作用。方法：采用压力感知量表（PSS-14）、广泛性焦虑量表(GAD-7、领悟社会支持量表(PSSS)、创伤后应激障碍自评量表(PCL-C)，对4997名消防官兵进行调查。结果：①压力感知可以显著正向预测创伤后应激障碍症状(t=43.947， P<0.001)；②焦虑在压力感知和创伤后应激障碍症状之间起部分中介作用，中介效应值为0.273；③压力感知和领悟社会支持的交互项对焦虑(t=-19.235， P<0.001)和创伤后应激障碍症状(t=-9.711， P<0.001)的预测作用显著。结论：压力感知不仅能直接导致消防员出现创伤后应激障碍症状，还能通过增加焦虑情绪间接导致创伤后应激障碍症状。在低领悟社会支持下，压力感知更容易导致消防员出现创伤后应激障碍症状和焦虑情绪，焦虑情绪的增加也更容易使消防员出现创伤后应激障碍症状。

Objective: To explore the relationship between perceived stress and posttraumatic stress disorder (PTSD), as well as the mediating effects of anxiety and moderating effects of perceived social support. Methods: A total of 4997 firefighters were surveyed by Perceived Stress Scale (PSS-14), Generalized Anxiety Disorder Scale (GAD-7), Perceived Social Support Scale (PSSS) and PTSD Checklist-Civilian Version (PCL-C). Results: ①Perceived stress positively predicted PTSD (t=43.947, P<0.001); ②Anxiety played a mediating role between perceived stress and PTSD, with a mediation effect value of 0.273; ③The interaction term of perceived stress and perceived social support significantly predicted anxiety symptom (t=-19.235, P<0.001) and PTSD (t=-9.711, P<0.001). Conclusion: Perceived stress not only directly affects PTSD, but also indirectly contributes to it through increased anxiety. At lower levels of perceived social support, perceived stress is more likely to lead to heightened anxiety and PTSD among firefighters. Additionally, increased anxiety further predisposes firefighters to PTSD.
