Past research has found that police officers who experience traumatic events on duty are more vulnerable to the development of Posttraumatic Stress Disorder (PTSD) and depression symptoms than the general population (Chopko, Am. J. Psychother. 64(1):55–72 2010; Lewis-Schroeder et al. 2018). Police officers also experience traumatic events that are not duty-related, which may have an influence on subsequent PTSD and depressive symptoms, but there is a lack of research into this possibility. This study used a cross-sectional survey of 241 police officers based in Alaska to understand the association of exposure to duty-related and personally experienced trauma and reported PTSD and depressive symptoms. Results indicated that the rate across the entire sample of probable PTSD was 5.4% and the rate of depression was 10.4%. This research found no significant relationship between exposure to duty-related traumatic events and PTSD symptoms. However, there was a significant relationship between the combination of duty-related and personally experienced traumatic events and PTSD symptoms. It is possible that duty-related traumatic experiences alone are not associated with PTSD symptoms because of effective police officer training and desensitization to trauma experienced on duty but more research is needed about this potential explanation. This study points to the need to better understand and address personally experienced trauma among police officers rather than focusing solely on duty-related traumatic experiences.

过去的研究发现，在执行任务时经历过创伤事件的警官比一般人群更容易出现创伤后应激障碍 (PTSD) 和抑郁症状 (Chopko, Am. J. Psychother. 64(1):55–72 2010；刘易斯-施罗德等人，2018）。警察也会经历与职责无关的创伤事件，这可能会影响随后的创伤后应激障碍和抑郁症状，但缺乏对这种可能性的研究。这项研究对阿拉斯加的 241 名警察进行了横断面调查，以了解暴露于与职责相关的和个人经历的创伤以及报告的 PTSD 和抑郁症状之间的关联。结果表明，整个样本中可能患有 PTSD 的率为 5.4%，抑郁率为 10.4%。这项研究发现，接触与职责相关的创伤事件与 PTSD 症状之间没有显着关系。然而，与职责相关和个人经历的创伤事件的组合与 PTSD 症状之间存在显着关系。由于有效的警官培训和对执勤经历的创伤脱敏，仅与执勤相关的创伤经历可能与 PTSD 症状无关，但需要对这种潜在的解释进行更多研究。这项研究指出，需要更好地理解和解决警官个人经历的创伤，而不是仅仅关注与职责相关的创伤经历。
