攻击性在大学生社会支持与自杀接受程度间的中介作用

Mediation effect of aggression on relationship between social support and suicide acceptability among college students

目的探讨攻击性在大学生社会支持与自杀接受程度间的中介作用。方法采用社会支持评定量表（SSRS）、Buss-Perry攻击性问卷中文版（AQ-CV）和自杀接受程度问卷，对黑龙江省4533名大学生进行问卷调查；使用SPSS19．0进行统计分析，包括描述性分析、单因素方差分析、相关分析和线性回归分析。结果大学生社会支持、攻击性和自杀接受程度的平均得分分别为（35．34±4．77）分、（61．67±15．42）分和（11．45±11．79）分；社会支持与攻击性、自杀接受程度间存在负相关关系（r=-0．256，r=-0．131，P〈0．01），大学生攻击性与自杀接受程度问存在正相关关系（r=0．308，P〈0．01）；回归分析发现，大学生攻击性在社会支持与自杀接受程度间起部分中介作用，中介效应占总效应之比为51．48％。结论社会支持不仅能直接影响大学生自杀接受程度，还可以通过攻击性对自杀接受程度产生间接影响。

Objective To explore the mediation effect of aggression on relationship between social support and suicide acceptability among college students. Methods 4 533 college students were collected to carry out a questionnaire survey, which includes Social Support Rating Scale, Chinese Version of Buss and Perry Aggression Questionnaire and suicide acceptability questionnaire; the data were analyzed by SPSS19.0, and the statistical methods include descriptive analysis ,one-way ANOVA ,correlation analysis and hierarchical regression analysis. Results The scores of social support, aggression and suicide acceptability were 35.34±4.77,61.67± 15.42,11.45±11.79, respectively. There were two negative correlations ： social support and aggression（ r=-0.256, P〈0.01 ）, social support and suicide acceptability （ r=-0.131, P〈0.01 ） ; besides ,the association of aggression and suicide acceptability was positive（ r= 0.308, P〈0.01 ）. Hierarchical regression analysis suggested that, aggression partially mediated the relationship between social support and suicide acceptability; and the mediating effect was 51.48%. Conclusion Social support has a direct impact on suicide acceptability ; and aggression can mediate the association of social support and suicide acceptability.
