Schoolmates of suicide victims at higher risk

Teens who have a classmate die of suicide are more likely to consider taking, or attempt to take, their own lives, according to a new study.

The idea that suicide might be "contagious" has been around for centuries, senior author Dr. Ian Colman, who studies mental health at the University of Ottawa, told Reuters Health.

Past studies supported the idea, but none had looked at such a large body of students, he said.
"There were a lot of surprising things about this study, we were surprised that the effect lasted so long and just how strong it was," Colman said.

Colman and his colleagues used data from a long-running national survey of more than 8,000 Canadian kids aged 12 to 17 years old. Students were asked about suicides of schoolmates, friends and their own thoughts of suicide, and researchers checked in with the kids two years later.

By the age of 17, one in four kids had a schoolmate who had committed suicide, and one in five knew the deceased personally, according to results published in the Canadian Medical Association Journal.

Source Article: Association between exposure to suicide and suicidality outcomes in youth

CMAJ 2013. DOI:10.1503/cmaj.121377

Abstract

Background: Ecological studies support the hypothesis that suicide may be "contagious" (i.e., exposure to suicide may increase the risk of suicide and related outcomes). However, this association has not been adequately assessed in prospective studies. We sought to determine the association between exposure to suicide and suicidality outcomes in Canadian youth.

Methods: We used 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. We included all respondents aged 12–17 years in cycles 3–7 with reported measures of exposure to suicide.

Results: We included 8766 youth aged 12–13 years, 7802 aged 14–15 years and 5496 aged 16–17 years. Exposure to a schoolmate's suicide was associated with ideation at baseline among respondents aged 12–13 years (odds ratio [OR] 5.06, 95% confidence interval [CI] 3.04–8.40), 14–15 years (OR 2.93, 95% CI 2.02–4.24) and 16–17 years (OR 2.23, 95% CI 1.43–3.48). Such exposure was associated with attempts among respondents aged 12–13 years (OR 4.57, 95% CI 2.39–8.71), 14–15 years (OR 3.99, 95% CI 2.46–6.45) and 16–17 years (OR 3.22, 95% CI 1.62–6.41). Personally knowing someone who died by suicide was associated with suicidality outcomes for all age groups. We also assessed 2-year outcomes among respondents aged 12–15 years: a schoolmate's suicide predicted suicide attempts among participants aged 12–13 years (OR 3.07, 95% CI 1.05–8.96) and 14–15 years (OR 2.72, 95% CI 1.47–5.04). Among those who reported a schoolmate's suicide, personally knowing the decedent did not alter the risk of suicidality.

Interpretation: We found that exposure to suicide predicts suicide ideation and attempts. Our results support school-wide interventions over current targeted interventions, particularly over strategies that target interventions toward children closest to the decedent.
