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

过去十年来，预防自杀一直是国家的优先事项。自残是自杀的一个预测因素，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，已知的自伤相关因素，如抑郁和药物使用，也会给社会带来重大负担，而且本身就是自杀的预测因素。了解澳大利亚青少年自伤的性质和程度，以及自伤、自杀意念和心理困扰之间的因果关系，将改善对自伤者的护理，改善他们的幸福感，减少他们进一步自伤的机会，并减少他们死于自杀的机会。

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.
