This study set out to investigate the utility of 4 often referred to behavioural antecedents of suicide attempts--suicide ideation, plans, threats and deliberate self-harm--in the prediction of suicide attempts and the identification of suicide attempters and nonattempters among adolescents. A total of 156 male and 151 female students aged between 14 and 17 years (mean = 15.8) attending one randomly chosen metropolitan state high school completed a questionnaire concerning a number of aspects of suicidal behaviour. The findings indicated that suicide ideation, plans and threats, and deliberate self-harm are associated with suicide attempting and that a combination of suicide plans and deliberate self-harm present a particularly worrying mixture. Further, a composite index of suicidality was demonstrated to have some utility in the identification of suicide attempters and nonattempters. These findings add further weight of evidence to the suggestion that adolescents who enter the spectrum of suicide behaviours are at high risk of making a suicide attempt, although this requires further investigation in a prospective study.
本研究旨在探讨自杀未遂的4种常被提及的行为先兆——自杀意念、计划、威胁和蓄意自伤——在预测自杀未遂以及识别青少年自杀未遂者和未自杀未遂者方面的效用。一所随机选取的大都市公立高中的156名男生和151名年龄在14至17岁（平均 = 15.8岁）的女生完成了一份关于自杀行为多个方面的问卷。研究结果表明，自杀意念、计划和威胁以及蓄意自伤与自杀未遂相关，而且自杀计划和蓄意自伤的组合呈现出一种特别令人担忧的情况。此外，自杀倾向综合指数在识别自杀未遂者和未自杀未遂者方面显示出一定效用。这些发现进一步证明了这样一种观点，即进入自杀行为范围的青少年有很高的自杀未遂风险，不过这需要在前瞻性研究中进一步调查。
