Adolescents exposed to suicidal behavior of others: prevalence of self-harm and associated psychological, lifestyle, and life event factors.

Exposure to suicidal behavior of others was examined among 3,881 Irish adolescents in the Child and Adolescent Self-harm in Europe (CASE) study. One third of the sample had been exposed to suicidal behavior, and exposed adolescents were eight times more likely to also report own self-harm. Exposed adolescents shared many risk factors with those reporting own self-harm. Those reporting both exposure and own self-harm presented the most maladaptive profile on psychological, life event, and lifestyle domains, but neither anxiety nor depression distinguished this group. Exposed adolescents are burdened by a wide range of risk factors and in need of support.
