| 背景 自杀是青春期和成年早期的重要公共卫生问题，生存理由和自我控制均与自杀尝试相关，但在大学生群体中探讨三者之间内在联系的研究证据不足。目的 探讨大学生自杀尝试、生存理由和自我控制之间的关系，以期为针对性地阻断自杀尝试行为的发展提供参考。方法 于2023年4月—5月，采用随机抽样法选取陕西省、四川省和重庆市10所高校的775名在读大学生为研究对象。采用自我控制量表（SCS）、青少年生存理由量表（RFL-A）以及自编自杀尝试问卷分别评定大学生的自我控制能力、生存理由水平和自杀尝试状况。采用Spearman相关分析考查各量表评分的相关性，采用Mplus 8.3进行作用路径分析。结果 共738名（95.32%）大学生完成有效问卷调查，检出99名（13.41%）大学生存在自杀尝试。大学生SCS评分与RFL-A评分呈正相关（r=0.329，P<0.01），SCS评分和RFL-A评分与自杀尝试均呈负相关（r=-0.194、-0.285，P均<0.01）。自我控制在生存理由与自杀尝试之间的间接效应值为-0.059（95% CI：-0.105~-0.018），占总效应的11.07%。自我控制的中介作用存在性别差异，男生组自我控制的间接效应值为-0.089（95% CI：-0.163~-0.030），占总效应的15.72%；女生组自我控制的间接效应不显著（95% CI：-0.407~0.115）。结论 生存理由可负向预测大学生的自杀尝试，自我控制可能是大学生生存理由与自杀尝试之间的作用路径，且自我控制的中介作用可能只在男性大学生中存在。 |

| Background Suicidal behavior in adolescence and early adulthood is a major public health concern， and suicide attempts are found to be associated with reasons for living and self-control， whereas there remains a striking lack of empirical research exploring the association among the three in college students.Objective To explore the relationship among suicide attempts， reasons for living and self-control， and to inform targeted efforts to prevent the development of suicidal behavior.Methods From April to May 2023， a sample of 775 college students from 10 colleges and universities in Shaanxi province， Sichuan province and Chongqing municipality were selected using random sampling method. All students were subjected to complete Self-Control Scale （SCS）， the Reasons for Living Inventory for Adolescents （RFL-A）， and the self-administered Suicide Attempt Questionnaire. Spearman correlation analysis was utilized to examine the correlation among the above scales in students， and mediation analysis was performed using Mplus 8.3.Results A total of 738 college students （95.32%） completed the effective questionnaire survey.Suicide attempts were detected in 99 college students （13.41%）. SCS score was positively correlated with RFL-A score （r=0.329， P<0.01）， and SCS score and RFL-A score were both negatively correlated with the risk of suicide attempts （r=-0.194， -0.285， P<0.01）. The indirect mediation effect value of self-control on the relationship between reasons for living and suicide attempts was -0.059 （95% CI： -0.105~-0.018）， accounting for 11.07% of the total effect. There was a gender difference in the mediating effect of self-control， among which the effect was significant in male group， with an indirect effect value of -0.089 （95% CI： -0.163~-0.030） and accounting for 15.72% of the total effect， whereas the mediating effect was not significant in female group （95% CI： -0.407~0.115）.Conclusion Reasons for living can negatively predict suicide attempts among college students， and self-control may play a mediating role in the relationship between reasons for living and suicide attempts among college students， and the mediating effect of self-control appears to be statistically significant only in male but not in female students. |
