维特效应描述了媒体（通常是名人）描述自杀事件后，完成自杀或企图自杀的比率增加。我们在 Reddit 上的 r/SuicideWatch 在线平台上展示了这种效应普遍存在的结果。我们检查了十名备受瞩目的自杀者死亡后的发帖活动和发帖内容。名人自杀报道后，发帖活动有所增加，发帖内容也发生了相当大的变化，表明自杀意念有所增加。具体来说，我们观察到名人自杀后的内容更有可能集中于内心，表现出社会担忧的减少，并充满更多的焦虑、愤怒和负面情绪。话题模型分析进一步揭示了这一时期的内容转向更加贬义的语气，带有自残和自杀倾向的证据。我们讨论了我们的研究结果对于为心理脆弱人群提供更好的社区支持的影响，以及在备受瞩目的自杀事件后建立自杀预防干预措施的潜力。
The Werther effect describes the increased rate of completed or attempted suicides following the depiction of an individual’s suicide in the media, typically a celebrity. We present findings on the prevalence of this effect in an online platform: r/SuicideWatch on Reddit. We examine both the posting activity and post content after the death of ten high-profile suicides. Posting activity increases following reports of celebrity suicides, and post content exhibits considerable changes that indicate increased suicidal ideation. Specifically, we observe that post-celebrity suicide content is more likely to be inward focused, manifest decreased social concerns, and laden with greater anxiety, anger, and negative emotion. Topic model analysis further reveals content in this period to switch to a more derogatory tone that bears evidence of self-harm and suicidal tendencies. We discuss the implications of our findings in enabling better community support to psychologically vulnerable populations, and the potential of building suicide prevention interventions following high-profile suicides.
