There is a suicide on the British railways every 36 hours. However, the reasons why people choose to die by train are not well understood.AimsTo explore factors influencing and discouraging the decision to attempt suicide on the railway networks.
We conducted an online survey and qualitative interviews with individuals who had contemplated or attempted suicide by train.
A total of 353 survey responders had considered and 23 had attempted suicide at rail locations (including railways and metro/underground); a third of these cases were impulsive. The most frequently reported motivations for contemplating or attempting suicide were perceptions of quick and certain lethality (54 and 37%, respectively) and easy access to rail settings (33 and 38%, respectively). The main factor discouraging people from rail suicide was its wider impact, especially on train drivers (19%). In qualitative interviews (N = 34) the desire to avoid intervention from others was also a common motivating factor for attempting suicide on the railway networks.
People attempt suicide by train because railway settings are easy to access and because of an inaccurate perception of certain and quick lethality. Tackling exaggerated perceptions of lethality may help reduce suicides by train.Declaration of interestNone.
英国铁路上每36小时就有一起自杀事件。然而，人们选择卧轨自杀的原因尚不清楚。
探讨影响和阻碍在铁路网络上企图自杀决定的因素。
我们对曾考虑或企图卧轨自杀的个人进行了在线调查和定性访谈。
共有353名调查受访者曾考虑过在铁路地点（包括铁路和地铁/地下铁道）自杀，23人曾尝试过；其中三分之一的案例是冲动行为。考虑或企图自杀最常报告的动机是认为死亡迅速且确定（分别为54%和37%）以及容易进入铁路区域（分别为33%和38%）。阻止人们选择铁路自杀的主要因素是其更广泛的影响，尤其是对火车司机的影响（19%）。在定性访谈（N = 34）中，避免他人干预的愿望也是在铁路网络上企图自杀的一个常见动机因素。
人们选择卧轨自杀是因为铁路区域容易进入，以及对死亡迅速且确定存在不准确的认知。解决对致命性的夸大认知可能有助于减少卧轨自杀事件。
无。
