Ecological studies support the hypothesis that suicide may be "contagious" (i.e., exposure to suicide may increase the risk of suicide and related outcomes). The study seeks to determine the association between exposure to suicide and suicidality outcomes in Canadian youth.
Using baseline information from the Canadian National Longitudinal Survey of Children and Youth between 1998/99 and 2006/07 with follow-up assessments 2 years later.
The study found that exposure to suicide predicts suicide ideation and attempts. The results support school-wide interventions over current targeted interventions, particularly over strategies that target interventions toward children closest to the decedent.
