Background: The public health sector has advocated for more innovative, technology-based, suicide prevention education for the community, to improve their ability to detect and respond to suicide risk. Emerging evidence suggests addressing the bystander effect through the Bystander Intervention Model (BIM) in education material may have potential for suicide prevention. Aims: The current study aimed to assess whether BIM-informed tools can lead to improved readiness, confidence and intent in the community to detect and respond to suicide risk in others. Method: A sample of 281 adults recruited from the community participated in a randomized controlled trial comprising a factsheet designed according to the BIM (intervention group) and a standard factsheet about suicide and mental health (control group). Participants' self-reported detecting and responding to suicide risk readiness, confidence, and intent when presented with a suicidal peer was tested pre- and postintervention and compared across time and between groups. Results: The intervention group had significantly higher levels of detecting and responding to suicide risk readiness, confidence, and intent than the control group at postintervention (all p < .001) with moderate-to-large effect sizes. Limitations: The study was limited by a homogenous sample, too low numbers at follow-up to report, and self-report data only. Conclusion: This study demonstrates BIM-informed suicide prevention training may enhance the community's intervention readiness, confidence, and intent better than current standard material. Further testing in this area is recommended. While results were statistically significant, clinical significance requires further exploration.

通过在线旁观者干预模型知情工具提高社区检测和应对自杀风险的能力。

背景：公共卫生部门提倡为社区提供更多创新的、以技术为基础的自杀预防教育，以提高他们发现和应对自杀风险的能力。新出现的证据表明，通过教育材料中的旁观者干预模型 (BIM) 解决旁观者效应可能具有预防自杀的潜力。目的：目前的研究旨在评估 BIM 知情工具是否可以提高社区的准备度、信心和意愿，以检测和应对他人的自杀风险。方法：从社区招募的 281 名成年人样本参加了一项随机对照试验，该试验包括根据 BIM（干预组）设计的资料单和关于自杀和心理健康的标准资料单（对照组）。参与者的 自我报告的检测和应对自杀风险的准备、信心和意图，在干预前后进行了测试，并在不同时间和组之间进行了比较。结果：干预组在干预后对自杀风险准备、信心和意图的检测和响应水平显着高于对照组（所有 p < .001），具有中到大的效应量。局限性：该研究受到同质样本、随访报告数量太少以及仅自我报告数据的限制。结论：这项研究表明，BIM 知情自杀预防培训可以比当前的标准材料更好地提高社区的干预准备、信心和意图。建议在这方面进一步测试。虽然结果具有统计学意义，
