Recently, there has been activity at public locations where people have died by suicide, including the erection of suicide prevention messages and memorials (decorations). This research looks at the impact of these decorations and associated media coverage of the decorations on suicidal behaviour at bridges. Incidents (n = 160) of suicidal behaviour on 26 bridges across motorways in England were analysed. Overall, there was no significant difference in the proportion of incidents pre-decoration versus post-decoration (p-value = .55). The incident rates were not significantly different pre- and post-decoration (p = .46). Only one bridge had statistically significantly more incidents post-decoration and media reporting (p = .03). However, following correction for multiple testing there was no significant difference in pre- and post-incident rates at any of the bridges. In total, 58% of bridges had a greater frequency of incidents when decorations were absent; however, this proportion was not statistically significant (p = .41). Further research is required to establish how suicide prevention messages are perceived. There does not appear to be any benefit, but it often generates media coverage which has been shown to increase risk.
最近，在公共场所出现了一些与自杀有关的活动，包括设立自杀预防信息和纪念物（装饰）。这项研究调查了这些装饰以及相关媒体对桥梁自杀行为的报道对自杀行为的影响。分析了英格兰 26 座高速公路上的 26 座桥梁上发生的 160 起自杀行为事件。总的来说，装饰前后事件的比例没有显著差异（p 值=0.55）。装饰前后的事件发生率没有显著差异（p=0.46）。只有一座桥在装饰和媒体报道后发生的事件明显更多（p=0.03）。然而，经过多次测试校正后，任何一座桥上的事件发生率都没有显著差异。总的来说，当没有装饰时，58%的桥梁发生事件的频率更高；然而，这一比例没有统计学意义（p=0.41）。需要进一步研究以确定如何感知自杀预防信息。目前似乎没有任何好处，但它经常会引发媒体报道，而媒体报道已被证明会增加风险。
