The authors assessed the occurrence of suicidal ideation, suicide attempts, major depression, and substance abuse in a sample of 424 apparently healthy college students 16-19 years old. Major depression and substance abuse were independent and interactive risk factors for suicidal ideation and for suicide attempts; substance abuse had a particularly deleterious effect on men. A prolonged desire to be dead was a more specific risk factor for a suicide attempt than was a thought of suicide. The authors conclude that suicidal ideation in the presence of major depression and/or substance abuse in older adolescents should call forth greater concern for lethality.
作者对424名16至19岁表面健康的大学生样本进行了自杀意念、自杀未遂、重度抑郁和药物滥用情况的评估。重度抑郁和药物滥用是自杀意念和自杀未遂的独立及交互风险因素；药物滥用对男性有特别有害的影响。与自杀想法相比，长期想死是自杀未遂更具特异性的风险因素。作者得出结论，年龄较大的青少年出现重度抑郁和/或药物滥用时的自杀意念应引发对致死性的更大关注。
