This study was conducted following the London bombings of 7 July 2005.
To assess the psychological impact of the 2005 London bombings on London Ambulance Service (LAS) personnel, risk factors for the development of psychological ill-health and employee awareness of post incident support.
A total of 525 LAS personnel involved in the bombings, and a control group of uninvolved staff, were sent a questionnaire 2 months after the bombings. Main outcome measures were the presence of probable post-traumatic stress disorder (PTSD) measured using the Trauma Screening Questionnaire and substantial psychological distress using a tool identical to that used to assess the impact of these bombings on the population of London.
Fifty-six per cent of those who responded were involved in the bombings. Overall, including controls, the response rate was 32% (341). Four per cent of respondents reported probable PTSD and 13% reported substantial distress. Probable PTSD was more common in those involved in the bombings (6% overall), those working at the disaster scene and, in particular, at one of the incident locations (where 50% of all probable PTSD cases worked). The majority of staff were aware of the post incident support available and how to access this, particularly if personnel were involved in the bombings.
The LAS did not report higher levels of probable PTSD and psychological distress than the rest of the London population; however, those more proximal to the incident were more likely to have been affected in spite of being aware of various staff support measures put in place.
本研究是在 2005 年 7 月 7 日伦敦爆炸事件之后进行的。
评估 2005 年伦敦爆炸事件对伦敦救护服务（LAS）人员的心理影响、心理健康不良发展的风险因素以及员工对事件后支持的认识。
共向 525 名参与爆炸事件的 LAS 人员和一组未参与的员工发送了一份问卷，时间是爆炸事件发生后 2 个月。主要观察指标是使用创伤筛查问卷（Trauma Screening Questionnaire）测量存在可能的创伤后应激障碍（PTSD）的情况，以及使用与评估这些爆炸事件对伦敦人口影响相同的工具测量存在明显心理困扰的情况。
回应者中有 56%参与了爆炸事件。总体而言，包括对照组在内，回应率为 32%（341 人）。4%的受访者报告存在可能的 PTSD，13%报告存在明显的困扰。在参与爆炸事件的人员（总体为 6%）、在灾难现场工作的人员，特别是在一个事件地点工作的人员（所有可能的 PTSD 病例中有 50%在那里工作）中，可能的 PTSD 更为常见。大多数员工都知道可获得的事件后支持以及如何获得这些支持，特别是如果人员参与了爆炸事件。
LAS 报告的可能 PTSD 和心理困扰水平并不高于伦敦其他人群；然而，尽管知道已经采取了各种员工支持措施，但与事件更接近的人员更有可能受到影响。
