目的 探讨负性生活事件与自杀意念的相关性.方法 采用分层整群随机抽样方法,对重庆市11所大学中的12114名大学生进行问卷调查,选用一般人口学资料调查量表了解社会人口学特征;用对个人生活的看法问卷评估最近1个月内的自杀意念;用自编生活事件调查问卷评估过去1年内经历的负性生活事件.结果 大学生最近1个月内自杀意念报告率为9.6%,随经历的负性生活事件数目增加,近期自杀意念发生率增高.x2检验表明,经历1件负性生活事件与未经历负性生活事件的自杀意念发生比率之间的差异有统计学意义(x2 =37.72,P<0. 01),经历2件及以上的负性生活事件与未经历负性生活事件的自杀意念发生比例之间的差异有统计学意义(x2 =65.46,P<0.01).多因素Logistic回归分析示,与家庭其他成员发生矛盾(OR=0. 295,95%CI 0.017~0. 571),被虐待(OR= 7.295,95%CI 6.049~9. 701)是大学生近期自杀意念产生的独立危险因素.结论 负性生活事件多,与家庭其他成员发生矛盾及被虐待与大学生近期自杀意念的出现有相关性.

The questionnaire of general demographic information was used to learn sociodemographic characteristics;the perspective on personal life questionnaire was applied to evaluate the suicidal ideation within recent 1 month and the self-designed life event scale was used to investigate the occurrence of negative life events in the past 1 year. Results The report rate of suicidal ideation within 1 month was 9.6%, the occurrence rate of short term suicidal ideation was increased with experiencing more negative life events. The x2 test showed that there was statistically significant difference in the proportion of suicidal ideation occurrence between college students experiencing 1 negative life event and those without experiencing the negative life event (x2 = 37.72,P<0.01) ;besides, the occurrence proportion of recent suicidal ideation had statistical difference between the college students with experiencing two or more negative life events and those without experiencing negative life event (x2 = 65.46,P<0.01). The multivariate Logistic regression analysis showed that the conflict with other family members (OR=0. 295,95%CI 0. 017-0. 571),abuse (OR=7. 295, 95%CI 6. 049-9. 701) were independentrisk factor for the recent suicidal ideation in college students. Conclusion Experiencing more negative life events, conflicting with other family members and abused by others have a correlation with the appearance of short term suicidal ideation in college students.
