Nearly three times as many Canadians – close to 8 per cent – thought of killing themselves in the first year of the COVID-19 pandemic than did in previous years, a new study led by Université de Montréal researchers suggests.
Based on an online survey of nearly 1,800 Canadian adults, the study also found that suicidal ideation was nearly twice as high (almost 11 per cent) among young people in their 20s than in people aged 30 and older (6.6 per cent).
The results are published this month in the Nature journal Scientific Reports.
"It's a sensitive subject," acknowledged the article's first author, Guillaume Dubé, who was an undergraduate student in sociology at UdeM at the time of the study and is now about to begin a Ph.D. in epidemiology.
"Why did the pandemic make people think about committing suicide? There are a number of reasons, losing their job because of the crisis being a major one," said sociology professor Éric Lacourse, who co-supervised the study with psychology professor Roxane de la Sablonnière.
"And that's not surprising given the context of dramatic social change caused by COVID-19, which affected not only society as a whole but also individual behaviours," said de la Sablonnière.
Members of UdeM's Laboratory on Social Changes, Adaptation, and Well-being, she and Lacourse conducted the study with Dubé aided by colleagues at McGill University, the Massachussetts Institute of Technology and Israel's Ben-Ilan University.
