Suicide is the second-leading cause of death among college students in the U.S. and is preventable. Approximately 1100 college students die by suicide each year. This study examined the prevalence and predictors of one-time and persistent suicide ideation, plans, and attempts reported during college.
Data were gathered prospectively over four years. Face-to-face interviews were conducted with 1253 first-year college students at one large mid-Atlantic university. Risk factors were measured in Year 1.
An estimated 12%(wt) of individuals experienced suicide ideation at some point during college, and of those individuals, 25% had more than one episode of ideation (persistent ideation; 2.6%(wt) of the overall sample). Ten individuals had a plan or attempt during college (0.9%(wt) of the sample). Risk factors for persistent suicide ideation included low social support, childhood or adolescent exposure to domestic violence, maternal depression, and high self-reported depressive symptoms. Persistent ideators differed from one-time ideators only by higher levels of depression (p=.027). Persistent ideators were no more likely than one-time ideators to have made a suicide plan or attempt during college (8% vs. 9%, respectively).
Although the sample size is large, only a small percentage of participants had persistent ideation, suicide plans or attempts during college.
These results have implications for programs aimed at identifying college students at risk for suicide. The accurate identification of college students at risk for suicide is an important step toward suicide prevention.
自杀是美国大学生的第二大死因,是可以预防的。每年约有 1100 名大学生自杀。本研究调查了大学期间一次性和持续性自杀意念、计划和尝试的发生率和预测因素。
数据在四年内进行前瞻性收集。在一所位于大西洋中部的大型大学对 1253 名一年级大学生进行了面对面访谈。在第 1 年测量了风险因素。
估计有 12%(wt)的个体在大学期间有过自杀意念,其中 25%的个体有不止一次的意念发作(持续性意念;占总样本的 2.6%(wt))。有 10 个人在大学期间有过计划或尝试自杀(占样本的 0.9%(wt))。持续性自杀意念的风险因素包括社会支持低、儿童或青少年期遭受家庭暴力、母亲抑郁和高自我报告的抑郁症状。持续性意念者与一次性意念者的唯一区别在于抑郁程度更高(p=.027)。持续性意念者在大学期间制定自杀计划或尝试自杀的可能性并不高于一次性意念者(分别为 8%和 9%)。
尽管样本量很大,但只有一小部分参与者在大学期间有持续性意念、自杀计划或尝试自杀。
这些结果对旨在识别有自杀风险的大学生的项目具有启示意义。准确识别有自杀风险的大学生是预防自杀的重要步骤。
