Universal suicide prevention in schools
Schools are one of the most important settings for health promotion and preventive interventions for young people and therefore became one of the main targets of youth suicide prevention programmes. School-based suicide prevention interventions are presented here according to the Universal/Selective/Indicated model. Evidence of the effectiveness of the different programmes is discussed. Universal interventions proved to be the most effective. Particularly, Signs of Suicide (SOS) and Youth Aware of Mental health (YAM) programme showed to significantly reduce suicidal ideation and behaviours. Gatekeeper training, especially QPR (Question, Persuade, and Refer), are also widely implemented but their efficacy was mostly evaluated as changes in knowledge and attitudes towards suicide. Screening programmes do not have iatrogenic effects and are effective in identifying at-risk students who otherwise would not be recognized, however their level of sensitivity and specificity require further improvements. Some systematic reviews suggested that a combination of programmes may be most effective.
