Suicide is the second leading cause of death among college-aged populations. This study examined the association of demographics (sexual orientation, gender identity, age, and race), sexual assault, posttraumatic stress symptoms (PTSS), and alcohol use with suicidality, current urge to self-harm, and current suicidal intent among a diverse sample of college students (n = 2,160) from two universities. Over half of participants reported any suicidality (63.5%), 12% reported current urge to harm themselves, and 5% reported current suicidal intent. A linear regression indicated that participants who identified as a sexual minority, gender minority, consumed more drinks per week, and had more severe PTSS reported higher levels of suicidality. University also was associated with suicidality. A negative binomial regression demonstrated that participants who identified as a sexual minority and had more severe PTSS had more current urge to harm themselves. Further, a negative binomial regression demonstrated that first-generation college students, students with more severe sexual assault histories, and students with more severe PTSS had higher current suicidal intent. Findings suggest that risk factors may differ for college students' general suicidality, self-harm urges, and suicidal intent, suggesting that these may be separate constructs. More comprehensive models, incorporating multiple risk factors and multiple ways of assessing suicidality, are needed to better understand the range of college student suicidal behavior and risks.

不同大学生的性侵犯、创伤后压力、酗酒和自杀倾向。

自杀是大学生死亡的第二大原因。这项研究考察了人口统计学（性取向、性别认同、年龄和种族）、性侵犯、创伤后应激症状（PTSS）和饮酒与自杀倾向、当前自残冲动以及不同群体中当前自杀意图之间的关系。来自两所大学的大学生样本（n = 2,160）。超过一半的参与者报告有自杀倾向（63.5%），12% 的人报告目前有伤害自己的冲动，5% 的人报告目前有自杀意图。线性回归表明，那些被认定为性少数群体、每周饮酒较多且患有更严重 PTSS 的参与者自杀倾向较高。大学也与自杀有关。负二项回归表明，被认定为性少数群体且患有更严重 PTSS 的参与者当前更容易伤害自己。此外，负二项式回归表明，第一代大学生、有更严重性侵犯历史的学生以及患有更严重 PTSS 的学生当前有更高的自杀意向。研究结果表明，大学生一般自杀倾向、自残冲动和自杀意图的风险因素可能有所不同，这表明这些因素可能是不同的。需要更全面的模型，纳入多种风险因素和多种自杀评估方法，以更好地了解大学生自杀行为和风险的范围。
