E-learning as a tool of suicide prevention training: A meta-analysis and systematic review

Suicide is a global health challenge. One prevention strategy is teaching individuals how to detect and respond to suicidality. These training have increasingly been delivered online. We searched WoS, Scopus, and PubMed from inception until the 20 September 2023 to evaluate e-learning efficacy as standardized mean changes and standardized mean differences. We synthesized main results using multilevel meta-analyses and subgroups using random-effects meta-analyses. Robins-I, RoB-II and trim-and-fill were used to assess the risk of bias. Of the 6516 initially screened articles, 26 were included. Overall, e-learning increased suicide prevention skills. Subgroups reported differing results: e-learning affected knowledge and self-efficacy more than behavior and attitudes. Efficacy, short duration, and low-cost suggest that e-learning may be feasible in teaching basic suicide prevention skills to lay people. However, current evidence suggests that health care professionals should not rely on e-learning as a training modality, except when no other form of training is available.
