Many people with suicidal thoughts do not receive treatment. The Internet can be used to reach more people in need of support.
To test the effectiveness of unguided online self-help to reduce suicidal thoughts.
236 adults with mild to moderate suicidal thoughts were randomised to the intervention (n=116) or a waitlist control group (n=120). Assessments took place at baseline, and 2, 4 and 6 weeks later. Primary outcome was suicidal thoughts. Secondary outcomes were depressive symptoms, anxiety, hopelessness, worry, and health status.
The intervention group showed a small significant effect in reducing suicidal thoughts (d=0.28). Effects were more pronounced for those with a history of repeated suicide attempts. There was also a significant reduction in worry (d=0.33). All other secondary outcomes showed small but non-significant improvements.
Although effect sizes were small, the reach of the internet could enable this intervention to help many people reduce their suicidal thoughts.

许多有自杀念头的人未接受治疗。互联网可用于帮助更多有需求的人获得支持。
测试无指导的在线自助对减少自杀念头的有效性。
236名有轻度至中度自杀念头的成年人被随机分为干预组（n = 116）或候补对照组（n = 120）。在基线以及2周、4周和6周后进行评估。主要结局是自杀念头。次要结局包括抑郁症状、焦虑、绝望、担忧和健康状况。
干预组在减少自杀念头方面显示出微小但显著的效果（d = 0.28）。对于有多次自杀未遂史的人，效果更为明显。担忧也有显著减少（d = 0.33）。所有其他次要结局显示出微小但不显著的改善。
尽管效应量较小，但互联网的覆盖面可使这种干预措施帮助许多人减少自杀念头。
