BackgroundMany people with suicidal thoughts do not receive treatment. The Internet can be used to reach more people in need of support.ObjectiveTo test the effectiveness of unguided online self-help to reduce suicidal thoughts.Method236 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.ResultsThe 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.ConclusionsAlthough effect sizes were small, the reach of the internet could enable this intervention to help many people reduce their suicidal thoughts.Trial registrationNetherlands Trial Register NTR1689.
