A prospective investigation of self-injury, suicidal ideation and psychological distress in Australian secondary school students

在过去的10年里，预防自杀一直是国家的优先事项。自我伤害是自杀的预测因素，会给家人和朋友带来相当大的痛苦，并与大量的医疗保健支出有关。此外，已知的自我伤害的相关因素，如抑郁和药物使用，也给社会带来了重大负担，本身就是自杀的预测因素。了解澳大利亚青少年自我伤害的性质和程度，以及自我伤害、自杀意念和心理痛苦之间的因果关系，将有助于改善对自我伤害者的护理，改善他们的幸福感，减少他们进一步自我伤害的机会，并减少他们自杀死亡的机会。

Suicide prevention has been a national priority for the past 10 years. Self-injury is a predictor of suicide, results in considerable distress for family and friends and is associated with significant health care expenditure. In addition the known correlates of self-injury, such as depression and substance use, also pose significant burden to society and are themselves predictors of suicide. Understanding the nature and extent of self-injury in Australian adolescents, and the causal relationships between self-injury, suicidal ideation and psychological distress, will improve the care given to those who self-injure, improve their well-being, decrease their chances of further self-injury, and decrease the chance they will die by suicide.
