In many countries, mental disorders are high among university students. We conducted a cross-sectional research design among 1767 university students (71.2% were females and the remaining were males) who attended public universities in Sarawak. Questionnaires related to a history of lifetime trauma, posttraumatic stress disorder (PTSD), and depressive symptoms together with suicide behavior were surveyed. Results showed that at least 87% of students had lifetime trauma once, 9.6% exhibited PTSD symptoms, 15.5% exhibited depressive symptoms, and 12.9% of participants reported having suicidal behavior. There were significantly more females who reported having suicidal behaviors than males. Ethnicity was significantly associated with PTSD symptoms. PTSD and depressive symptoms were significant predictors of suicidal behavior. Other significant predictors for suicide behavior among those who were traumatized were near drowning, sexual assault, losing a family member, neglect, and bullying. This study provides a significant understanding of the link between PTSD, depressive symptoms, and suicidal behavior among Malaysian university students.

在许多国家，大学生的精神障碍比例很高。我们对就读于砂拉越公立大学的 1767 名大学生（71.2% 为女性，其余为男性）进行了横断面研究设计。调查了与终生创伤史、创伤后应激障碍 (PTSD) 和抑郁症状以及自杀行为相关的问卷。结果显示，至少 87% 的学生有过一次终生创伤，9.6% 的学生表现出 PTSD 症状，15.5% 的学生表现出抑郁症状，12.9% 的参与者报告有自杀行为。报告有自杀行为的女性明显多于男性。种族与创伤后应激障碍症状显着相关。创伤后应激障碍和抑郁症状是自杀行为的重要预测因素。受创伤者自杀行为的其他重要预测因素包括溺水、性侵犯、失去家人、忽视和欺凌。这项研究对马来西亚大学生的创伤后应激障碍、抑郁症状和自杀行为之间的联系提供了重要的理解。
