Evaluating Primary Suicide Prevention in Adolescents With Risk Factors

Recruiting now · Not applicable

Conditions studied: Suicide Prevention

In brief

Suicide is one of the main causes of death among teenagers. Because it is preventable, primary prevention of suicide has become a public health priority, with encouraging results in promoting suicide awareness and reducing suicidal thoughts among adolescents. However, the lack of studies conducted among vulnerable populations (i.e., marginalised, disengaged and disadvantaged) is a major gap, even though these populations present an increased risk of suicidal behaviour. The aim of this project is to test the effectiveness of a brief primary suicide prevention intervention for vulnerable adolescents, using a randomised controlled trial. Vulnerable adolescents include those 1) detained in juvenile detention centres, 2) at risk of dropping out of school, 3) undergoing treatment for psychiatric disorders, 4) belonging to a sexual or gender diversity, 5) affected by chronic conditions, or 6) with relational/familial problems. The main aim is to test the effectiveness of the intervention on a composite measure of suicide awareness, psychological distress and suicidal thoughts. The project will also explore other issues that present challenges for vulnerable populations: access to primary suicide prevention and non-response bias. The study will provide relevant results to address the current lack of high-quality evidence for primary suicide prevention in adolescents.
