Knowing someone who attempted suicide raises young people’s own risk - new study
A new study of over 2,000 young people suggests that exposure to peers' suicidal behaviors significantly increases an individual's own risk of suicidal thoughts and depression. The research highlights the role of both in-person and digital social networks in the contagion effect.
Why it matters
Understanding the mechanics of suicide contagion is vital for developing effective mental health interventions for adolescents and young adults.
Scientists have long known suicide can be “ contagious ” in young people. This means knowing someone who has attempted suicide makes teens and young adults more likely to develop suicidal thoughts and behaviours themselves.
But despite decades of research, it has not been clear precisely how this works.
A new study of more than 2,000 young people, done by a US research group and published today, offers some new insights.
Suicidal thoughts and behaviours typically first emerge during adolescence and young adulthood. This is also when peer relationships take on increasing importance in young people’s lives.
And we know the risk of suicide is strongly linked to this peer influence during adolescence. Research shows the suicidal behaviours of individuals within a close network can lead to their peers also developing suicidal thoughts and behaviours.
