A recent cluster trial  covered over 11,000 pupils in 168 schools randomised to three different types of intervention or control. The interventions were:
- Educating teachers to spot children at risk;
- A programme delivered by outside instructors, which included role play and other measures aimed at enhancing resilience and reducing negative thoughts;
- A screening service.
All interventions were associated with a reduced risk of attempted suicide, but this was substantial and statistically significant only for the second intervention targeting adolescents directly. CLAHRC WM has programmes of youth psycho-prophylaxis and the Director was mega-impressed by this study.
