Searching for Psychological Predictors of Suicidal Ideation in University Students

ABSTRACT The present study aims to identify psychological predictors of suicidal ideation in university students. We collected a sample of 366 participants, representing a population of 7102 students from a university in northern Portugal (95% CI). Both in the whole sample and in the intra-gender analysis, students with suicidal ideation revealed higher levels of depressive symptoms, loneliness, social anxiety and fears of abandonment, and lower levels of comfort with intimacy and trust in others. Loneliness and depression are significant predictors of suicidal ideation, with an odds ratio of 1.095 and 1.108, respectively. The results were consistent with those found in the literature, and call for more research and implementation of intervention protocols in university populations.

摘要
本研究旨在识别大学生自杀意念的心理预测因素。本研究纳入366名参与者作为研究样本，该样本覆盖葡萄牙北部某大学7102名学生的总体人群，置信区间为95% CI。无论在全样本分析还是性别亚组分析中，存在自杀意念的大学生均表现出更严重的抑郁症状、孤独感、社交焦虑及被遗弃恐惧，同时在亲密关系舒适度与人际信任度上得分更低。孤独感与抑郁均为自杀意念的显著预测因素，其优势比（odds ratio）分别为1.095与1.108。本研究结果与现有文献报道一致，呼吁开展更多相关研究，并在高校人群中推进干预方案的落地实施。
