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。

Abstract: Objective To 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.Methods In 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.Results A 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).Conclusion The life meaning partially mediated the relationship between family functioning and suicide risk in college students.
