This retrospective study examined risk and protective factors for the development of posttraumatic stress disorder (PTSD) in a sample of 132 Canadian police officers. Structured interviews were conducted in order to assess the most distressing work-related traumatic events and determine diagnoses of full or partial PTSD. Participants completed self-administered questionnaires assessing several potential predictors. The results suggested that 7.6% of the participants developed full PTSD, whereas 6.8% had partial PTSD following an incident at work. A multiple logistic regression analysis indicated that the most potent risk factor for the development of full or partial PTSD was peritraumatic dissociation. Social support from colleagues during the event emerged as a significant protective factor. Clinical implications of the findings are discussed.
本回顾性研究调查了 132 名加拿大警察样本中创伤后应激障碍（PTSD）发展的风险和保护因素。进行了结构化访谈，以评估最痛苦的与工作相关的创伤性事件，并确定完全或部分 PTSD 的诊断。参与者完成了自我管理问卷，评估了几个潜在的预测因素。结果表明，7.6%的参与者在工作事件后出现完全 PTSD，6.8%的参与者出现部分 PTSD。多元逻辑回归分析表明，完全或部分 PTSD 发展的最有力风险因素是创伤期分离。事件期间来自同事的社会支持是一个重要的保护因素。讨论了这些发现的临床意义。
