BACKGROUND
Many people with suicidal thoughts do not receive treatment. The Internet can be used to reach more people in need of support.
OBJECTIVE
To test the effectiveness of unguided online self-help to reduce suicidal thoughts.
METHOD
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.
RESULTS
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.
CONCLUSIONS
Although effect sizes were small, the reach of the internet could enable this intervention to help many people reduce their suicidal thoughts.
TRIAL REGISTRATION
Netherlands Trial Register NTR1689.
背景
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。
目的
测试无指导的在线自助对减少自杀念头的有效性。
方法
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。
结果
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。
结论
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。
