大学生人格因素与自杀意念的关系

The Relationship between Personality Factors and Suicide Ideation of Undergraduates

目的探讨大学生人格因素与自杀意念的关系。方法采用大五人格问卷(NEO-FFI)和自杀可能性量表(SPS)对6154名大学生进行测查。结果①有无自杀意念者之间的人格特征存在显著差异(t=26.28,P<0.001);②相关分析表明,自杀意念与神经质呈正相关(r=0.41,P<0.001),与其他人格因素呈负相关(r=-0.35,P<0.001);③逐步回归分析表明,神经质、宜人性、外倾性和开放性等4种人格因素进入自杀意念的回归方程。结论大学生的自杀意念受其人格因素的影响。其中神经质对自杀意念具有正向的预测作用;宜人性和外倾性对自杀意念具有负向的预测作用。

Objective To explore the relationship between suicide ideation and the big five personality of undergraduates. Meth- ods NEO Five--Factor Inventory and the Suicide Probability Scale were used to test 6154 college freshmen. Results ① There was significant difference in average score of personality dimensions（t= 26.28,P〈0. 001）between those who had suicide ideation or not. ② Correlation analysis showed that there was a high positive correlation between neurotic and suicide ideation,and a high negative correlation between other personality dimensions and suicide ideation.③ Stepwise regression analysis resulted that four variables （neuroticism,agreeableness,extroversion and openness）entered the regression equation and predicted 20.4% of the total variance of suicide ideation. Conclusion Suicide ideation of undergraduates is influnced by personality. Suicide ideation is positiaely predicted by neuroticism,and negatively predicted by extroversion and agreeasleness.
