For which strategies of suicide prevention is there evidence of effectiveness?

This Health Evidence Network (HEN) synthesis report notes that suicide rates among adolescents and young adults have increased considerably over the last decades. In addition, many widely-used suicide prevention programmes have never been scientifically assessed, thus making it uncertain which are effective.

Due to the limited evidence and the heterogeneity of the interventions, it is not possible to determine if onesingle intervention was more effective than another. A broad array of suicide preventive interventionsaddressing different risk factors at various levels will be required.
