Suicidal behavior, especially amongst adolescents, has been linked to other adolescents complete and attempted suicide. Swanson and Colman looked at the association between exposure to suicide and suicidality outcomes in youth. They used baseline information from the Canadian National Longitudinal Survey of Children and Youth between 1998-1999 and 2006-2007, with follow-up assessments 2 years later. This included 8766 youth aged 12-13 years, 7802 patients aged 14-15 years, and 5496 patients aged 16-17 years. They determined that knowing someone who had committed suicide was associated with increased suicidality outcomes for all age groups. Exposure to suicide predicts ideation and attempts. [76]
