Non-suicidal self-injury (NSSI) and suicidal behaviour are widespread phenomena, especially in adolescence. This article provides an overview of the clinical criteria for, and diagnostic symptoms of, these behaviours as well as possible explanations (“gateway theory”; “third variable theory”; “theory of acquired capability for suicide”) for the well-established connections between NSSI and suicidal behaviour. Furthermore, the role of NSSI as a visible risk marker for the identification of adolescents with mental health problems or an increased risk of suicide is discussed and existing population-based screening procedures (Columbia Suicide Screen; ProfScreen) are explained. Particularly during the sensitive period of adolescence, the identification of adolescents at risk and the increase of help-seeking behaviour plays an important role in order to prevent chronification of NSSI and suicidal behavior and to buffer negative effects on mental health and psychosocial functioning.
