Objectives: Youth suicide rates are unacceptably high. Schools have long been accepted as an appropriate setting for suicide prevention activities. This review aims to synthesise the evidence for all types of suicide prevention interventions across educational settings. Methods: The review draws on two previous reviews conducted by the authors. In order to be included, studies had to test a specific suicide prevention intervention in an educational setting, have a suicide-related outcome and target young people. Results: A totally of 21 studies were included: 17 were conducted in school settings and four in universities. Seven of the school-based studies (41%) and one of the university studies (25%) were randomised controlled trials. Overall, the trials conducted in schools reported positive effects, as did four of the non- randomised controlled trials. Two of the university-based studies reported positive effects. Both universal and indicated interventions showed positive results; no iatrogenic effects were reported. Conclusions: School-based studies can have a positive impact on suicide-related behaviour and, overall, do not appear to cause harm. Study quality is variable, and the number of studies conducted in school settings far exceed those conducted in universities. These gaps need to be addressed by future research.
