Community-level interventions are a key part of suicide prevention. The effectiveness of these strategies vary and objective measurement of the efficacy of these interventions are often challenging. Evidence shows that preventing access to means of suicide in the community, and ongoing education and awareness among primary care healthcare professionals about mental illness and suicide, both are effective, universal-level preventive strategies. Increasing awareness and mental health literacy among young people in schools shows promise, though most evidence is from high-income countries. Trials have demonstrated that brief follow-up contact interventions (BCI), such as sending postcards, text messages or a follow-up phone call, are effective in reducing suicidal ideation and repetition of suicide attempts.
