The purpose of this study was to examine the longitudinal relationship between aggression and suicide ideation when controlling for other externalizing (i.e., alcohol misuse and risk-taking) and internalizing (i.e., depression and sleep problems) risk factors in an active duty, military sample. Preexisting data from a longitudinal study were analyzed to assess the wellness of service members across the deployment cycle. Participants were 944 active duty service members (95% male, 48% between 18 and 24 years old) who completed surveys upon initial return from deployment and approximately 3 months later. After controlling for other externalizing (alcohol misuse, risk-taking) and internalizing (depression, sleep problems) risk factors, service members reporting aggression were significantly more likely to report suicide ideation than those reporting no aggression (OR = 3.19; OR 95% CI: 1.16-8.80). The independent nature of the relationship between anger and suicidality suggests aggression may be an important indicator of suicidality for service members. Understanding the role of aggression in suicidality may improve the ability to identify at-risk service members and to develop effective interventions to reduce suicide risk.
本研究旨在探讨在控制其他外在（即酗酒和冒险行为）和内在（即抑郁和睡眠问题）风险因素的情况下，攻击行为与自杀意念之间的纵向关系，该研究对象为现役军事样本。对一项纵向研究的现有数据进行了分析，以评估在部署周期中军人的健康状况。参与者为 944 名现役军人（95%为男性，48%年龄在 18 至 24 岁之间），他们在部署后首次返回时以及大约 3 个月后完成了调查。在控制其他外在（酗酒、冒险行为）和内在（抑郁、睡眠问题）风险因素后，报告有攻击行为的军人报告自杀意念的可能性明显高于报告无攻击行为的军人（OR=3.19；OR95%CI：1.16-8.80）。愤怒和自杀意念之间关系的独立性表明，攻击行为可能是军人自杀意念的一个重要指标。了解攻击行为在自杀意念中的作用可能有助于提高识别高风险军人的能力，并制定有效的干预措施来降低自杀风险。
