teen Mental Health First Aid as a school-based intervention for improving peer support of adolescents at risk of suicide: Outcomes from a cluster randomised crossover trial.

teen Mental Health First Aid is effective in increasing recognition of and intentions to assist a suicidal peer. Although the open discussion of mental health first aid for a suicidal peer was distressing for some students, results suggest this was transient and not associated with harm. Future studies are required to ascertain whether these increases are indeed associated with better provision of support and prevention of youth suicide.
