We examined risk factors for suicidal behaviors (i.e., suicidal ideation and suicide attempts) in the absence of depression during adolescence. Using 6,788 adolescents from the National Longitudinal Survey of Children and Youth (NLSCY), we identified participants with "no recent history of depression." We then tested the effects of risk factors at age 14-15 on suicidal behaviors at age 16-17. Absence of recent depression history negatively predicted both suicidal ideation and suicide attempt. However, among those with no history of depression, substance use and the presence of a chronic illness both increased the risk of suicidal behaviors. Suicidal behavior in adolescents in the absence of depression history may be explained by factors such as substance use and chronic illness.
我们研究了青少年期无抑郁症状时自杀行为（即自杀意念和自杀未遂）的风险因素。利用来自全国儿童和青少年纵向调查（NLSCY）的6788名青少年，我们确定了“近期无抑郁病史”的参与者。然后，我们测试了14 - 15岁时风险因素对16 - 17岁时自杀行为的影响。近期无抑郁病史对自杀意念和自杀未遂均有负向预测作用。然而，在无抑郁病史的人群中，物质使用和慢性病的存在均增加了自杀行为的风险。青少年在无抑郁病史情况下的自杀行为可能由物质使用和慢性病等因素来解释。
