Authors' conclusion: students 16 to 18 years old have a strong association between bullying and suicidal thoughts (item: "life is not worth living"). When the harassment was frequent, suicidal thoughts were eight times more frequent than when the harassment was absent. Furthermore, this association was independent of previous psychiatric morbidity.
Reviewers' commentary: bullying is associated with suicidal ideation, regardless of psychiatric disorders. Although this cross-sectional study does not allow determining the casual association, it supports a strong association between suicidal ideation and bullying. These findings provide further evidence that bullying must be taken seriously. Therefore, its prevention, early detection and support for victims are of paramount importance.
