Beyond mental disorders: The role of child maltreatment in childhood suicidal behaviour

Journal article

Suicide is one of the leading causes of death in children aged 14 years and under in Australia, and child maltreatment is consistently identified as an antecedent. Despite this, not enough is known about the pathways from child maltreatment to suicidal behaviour, hampering prevention efforts. In this perspective, we examine the association between (1) various types of childhood maltreatment, and (2) the presence of mental disorders, and subsequent suicidal behaviours in children aged 14 years and under. We present a conceptual model of childhood suicidal behaviours which incorporates both direct and indirect mechanisms by which maltreatment (and other risk factors) exert an influence. Bodily intrusive maltreatment, especially sexual and physical abuse, significantly increases the risk of suicidal behaviours in childhood. Other forms of maltreatment, such as neglect and emotional abuse, may also contribute. While the presence of a mental disorder is another prominent risk factor for suicidal behaviours in adolescents and adults, there is less evidence of this association in childhood. Efforts to prevent child maltreatment can support suicide prevention efforts in children and other age groups. In addition, screening for suicidal behaviours and targeted interventions should be prioritised for populations at increased risk, particularly children with a history of maltreatment and their families.
