This study compared the severity of chronic idiopathic urticaria (CIU) and psychiatric symptoms between patients with different levels of posttraumatic stress disorder (PTSD) and investigated a model depicting the interrelationship between PTSD from past trauma, personality traits, coping strategies, CIU severity and psychiatric symptom severity. One hundred CIU and 60 allergy patients participated in the study, completing measures on PTSD, psychiatric symptoms, personality traits and coping strategies. The results showed that for CIU patients, 7%, 40 and 34% met the diagnostic criteria for no-PTSD, partial-PTSD and full-PTSD respectively whereas for allergy patients, 15%, 45 and 18% met the same criteria. Apart from CIU, psychiatric symptom severity differed significantly between diagnostic groups. PTSD was associated with coping strategies which were in turn associated with CIU severity and psychiatric symptom severity. PTSD was not significantly associated with personality. Emotion-focused coping mediated PTSD and CIU severity, PTSD and psychiatric symptom severity and neuroticism and CIU severity. To conclude, psychiatric symptom severity varies depending on the level of PTSD among CIU patients. Neurotic patients with a high level of PTSD from past trauma show raised CIU and psychiatric symptom severity when using emotion-focused coping strategies.
本研究比较了不同创伤后应激障碍（PTSD）水平的慢性特发性荨麻疹（CIU）患者的严重程度，并探讨了一个描述 PTSD 来自过去创伤、人格特质、应对策略、CIU 严重程度和精神症状严重程度之间相互关系的模型。100 名 CIU 患者和 60 名过敏患者参加了这项研究，完成了 PTSD、精神症状、人格特质和应对策略的测量。结果表明，对于 CIU 患者，分别有 7%、40%和 34%符合无 PTSD、部分 PTSD 和完全 PTSD 的诊断标准，而对于过敏患者，分别有 15%、45%和 18%符合相同的标准。除了 CIU 之外，不同诊断组之间的精神症状严重程度也有显著差异。PTSD 与应对策略相关，而应对策略又与 CIU 严重程度和精神症状严重程度相关。PTSD 与人格特质无显著相关性。情绪聚焦应对方式在 PTSD 和 CIU 严重程度、PTSD 和精神症状严重程度以及神经质和 CIU 严重程度之间起中介作用。总之，CIU 患者的精神症状严重程度取决于 PTSD 的水平。具有高 PTSD 水平的神经质患者在使用情绪聚焦应对策略时，CIU 和精神症状严重程度会升高。
