This article first presents a portrait of the situation by outlining the highlights of the 2010–2011 Québec Health Survey of High School Students report on violence in youth romantic relationships and the main socio-demographic and economic factors associated with it.
Secondly, the article presents the analysis results of the links between the use of psychoactive substances and violence suffered or inflicted by young people in the context of their romantic relationships. This is followed by the results of an analysis of the links between such violence and sexual behaviour. Where possible, data are presented by grade level or sex.
Finally, a conclusion brings together the main findings, some of which are put into perspective with the results of other studies on violence in youth romantic relationships.
