The objective of the SOS-trial is to examine if an online self-help intervention is effective in reducing suicidal thoughts among people at risk of suicide. The SOS-trial is a randomized, wait-list controlled trial with 1:1 allocation ratio. A total of 438 people with suicidal thoughts will be allocated to the intervention condition (N=219) or the control condition (N=219). The intervention condition consists of a six-week internet-based self-help therapy intervention. The control condition consists of a waiting list assignment for 32 weeks. The primary hypothesis is that the intervention is superior to the control condition in reducing suicidal thoughts at post-test (6 weeks). The SOS-trial is a partial replication of a previously conducted Dutch trial.
