摘　　要：目的 探讨生命意义感在大学生乐观主义与自杀风险之间的调节效应与中介效应,为进一步采取自杀干预措施提供依据.方法 采用自杀行为问卷-修订版（SBQ-R）、生活取向问卷（修订版）（LOT-R）、中文人生意义问卷（C-MLQ）对1310名在校大学生进行问卷调查.结果 大学生自杀风险、乐观主义和生命意义感的得分分别为（5.04±2.28）分、（11.22±2.07）分、（37.22±5.22）分.乐观主义与自杀风险存在显著负相关（r=-0.22,P＜0.01）,乐观主义与生命意义感存在显著正相关（r=0.28,P＜0.01）,生命意义感与自杀风险存在显著负相关（r=-0.18,P＜0.01）.生命意义感在乐观主义与自杀风险间调节效应不显著（P＞0.05）,生命意义感部分中介乐观主义与自杀风险的关系（P＜0.01）,效应值为0.07,中介效应占总效应的比例为17％.结论 生命意义感在大学生乐观主义与自杀风险之间的调节效应不存在,而是发挥部分中介作用.Objective To explore the moderating or mediating effects of life-meaning between optimism and suicide risk in undergraduates.Methods A total of 1310 college students from one Chinese university completed a survey that included Suicidal Behaviors Questionnaire-Revised （SBQ-R）,the Life Orientation Test-Revised （LOT-R） and the Chinese meaning in life questionnaire （C-MLQ）.Results The total scores of SBQ-R,LOT-R and C-MLQ of undergraduate were （5.04 ± 2.28）,（11.22 ± 2.07） and （37.22 ± 5.22）,respectively.Optimism had significant negative correlation with suicide risk （r =-0.22,P 〈 0.01）,and positive correlation with life-meaning （r=0.28,P〈0.01）.Life-meaning had significant negative correlation with suicide risk （r=-0.18,P〈0.01）.The life-meaning＇s moderating effects between optimism and suicide risk were not significant（P 〉 0.05）,while the relationship between optimism and suicide risk was mediated by life-meaning,and the mediating effect was 0.07,which accounted for 17% of the total effects.Conclusion Life-meaning doesnt morderating effect,but partially mediates the relationship between optimism and suicide risk.
