摘　　要：目的探讨大一新生生命意义感在其家庭功能与自杀风险之间的中介效应,为进一步预防大学生自杀提供依据。方法 2015年11月,选取南方医科大学全日制本科2015级2 900例大一全体新生为研究对象进行问卷调查。调查问卷包括人口学资料、自杀行为问卷-修订版(SBQ-R)、家庭关怀度指数问卷(APGAR)、生命意义量表(MLM)。分析大一新生生命意义感在其家庭功能与自杀风险之间的中介效应。结果共发放调查问卷2 900份,回收有效问卷2 787份,有效回收率为96.1%。2 787例大学生中男979例(35.1%),女1 808例(64.9%);平均年龄(18.4±0.8)岁。大学生SBQ-R、APGAR、MLM得分分别为(4.2±1.5)、(7.8±2.3)、(129.9±17.5)分;大学生APGAR、MLM得分与SBQ-R得分呈负相关(P<0.05);大学生MLM得分与APGAR得分呈正相关(P<0.05)。APGAR对自杀风险的直接效应显著(β=-0.176,P<0.001),中介变量MLM得分对自杀风险的负向预测作用显著(β=-0.270,P<0.001),说明生命意义感在家庭功能和自杀风险之间存在部分中介效应,效应值为0.12,中介效应占总效应的比例为41%。结论生命意义感在大学生家庭功能与自杀风险之间起部分中介作用。ObjectiveTo explore the mediating effects of life meaning between family functioning and suicide risk in freshmen,providing a reference for the delivery of suicide prevention interventions for this population.MethodsIn November 2015,all the 2015 admitted full-time undergraduate students（2 900 cases） from Southern Medical University were recruited in this survey using self-developed Demographic Questionnaire,Suicide Behaviors Questionnaire-Revised （SBQ-R）,Family APGAR （APGAR） and Meaningful Life Measure （MLM）.The mediating effects of life meaning between family functioning and suicide risk in them were analyzed.ResultsA total of 2 787 cases〔including 979 males（35.1%） and 1 808（64.9%） females with a mean age of （18.4±0.8） years〕 returned responsive questionnaires,with a response rate of 96.1%.The mean score for SBQ-R,APGAR and MLM achieved by the respondents was （4.2±1.5）,（7.8±2.3）,（129.9±17.5）,respectively.Both APGAR and MLM scores had significant negative correlation with SBQ-R score（P〈0.05）.And there was a significant positive correlation between MLM and APGAR scores（P〈0.05）.The suicide risk was influenced directly and significantly by the APGAR score（β=-0.176,P〈0.001）,and it decreased obviously with the increase of the importance of mediation variable of MLM score（β=-0.270,P〈0.001）,which indicated that the partial mediating effect of life meaning on the relationship between family functioning and suicide risk was significant,with an effect size of 0.12（accounting for 41% of the total effect）.ConclusionThe life meaning partially mediated the relationship between family functioning and suicide risk in college students.
