Transmission is an important concept in suicide prevention. It can occur when exposure to another person's death by suicide (or to suicide-related information more generally) draws attention to suicide or highlights specific suicide methods. In this paper, the fourth in a Series on a public health approach to suicide prevention, we contend that the transmissibility of suicide must be considered when determining optimal ways to address it. We draw on five examples of how transmission might occur and be prevented. The first two examples relate to transmission initiated by representations of suicide in traditional and new media. The third concerns transmission that leads to suicide clusters, and the fourth considers a specific setting in which transmission occurs, namely secondary schools. Finally, we discuss how suicide risk might be countered by the transmission of suicide prevention messages in media campaigns.

与自杀传播性相关的公共卫生措施


传播是预防自杀的一个重要概念。当暴露于他人的自杀死亡（或更普遍的自杀相关信息）引起人们对自杀的关注或强调特定的自杀方法时，就会发生自杀。在本文中，关于预防自杀的公共卫生方法系列的第四篇，我们认为在确定解决自杀的最佳方法时，必须考虑自杀的传播性。我们借鉴了五个例子来说明传播是如何发生和预防的。前两个例子与传统媒体和新媒体中对自杀的表现所引发的传播有关。第三项研究涉及导致自杀聚集性的传播，第四项研究考虑了发生传播的特定环境，即中学。最后，我们讨论了如何通过在媒体活动中传播自杀预防信息来对抗自杀风险。
