反社会人格特质对未成年犯攻击行为的影响:一个有调节的中介模型

Influence of antisocial personality on aggressive behavior of juvenile delinquents:A mediating model with regulation

目的:探讨反社会人格特质对未成年犯攻击行为的影响以及冲动性和黑暗人格在二者关系中的作用。方法:采用反社会过程筛查表自评版、简式冲动量表、攻击性问卷、黑暗三联征调查量表对668名未成年犯进行调查。结果:①反社会人格特质与攻击行为、冲动性、黑暗人格均呈显著正相关(r=0.382,0.361,0.500;P<0.001);攻击行为与冲动性、黑暗人格呈显著正相关(r=0.549,0.498;P<0.001);冲动性与黑暗人格呈显著正相关(r=0.427,P<0.001)。②反社会人格特质部分通过冲动性的中介作用正向预测攻击行为,间接总效应比重为44.67%。③冲动性中介作用受到黑暗人格的调节,在低黑暗人格个体中,冲动性在反社会人格特质与攻击行为之间有显著的中介作用(simple slope=0.222,t=5.713,P<0.001);对于高黑暗人格的个体,冲动性在反社会人格特质与攻击行为之间的中介效应不显著(P>0.5)。结论:反社会人格特质可以通过未成年犯的冲动性间接预测其攻击行为。冲动性在反社会人格特质与攻击行为之间受黑暗人格水平的调节,低黑暗水平组被试正向预测冲动性;高黑暗水平组被试对于冲动性则没有预测作用。

Objective:To explore the influence of antisocial personality traits on the attack behavior of juvenile offenders,and the role of impulsive and dark personalities in their relationship.Methods:A total of 668 juvenile offenders were investigated by using antisocial process screening scale,short impulse scale,aggression questionnaire and dark triad.Results:①Antisocial personality traits were positively correlated with aggressive behavior,impulsiveness and dark personality(r=0.382,0.361,0.500;P<0.001);There were significant positive correlations between beating behavior and impulsive and dark personality(r=0.549,0.498;P<0.001);Impulsiveness and dark personality were positively correlated(r=0.427,P<0.001).②The antisocial personality trait partially predicted aggressive behavior through impulsivity mediation,and the proportion of indirect total effect was 44.67%.③Impulsive mediation was modulated by dark personality,in low dark personality individuals,impulsivity played a significant role in mediating between antisocial personality traits and aggressive behavior(simple slope=0.222,t=5.713,P<0.001);And in individuals with high dark personality,impulsiveness had no significant mediating effect between antisocial personality traits and aggressive behavior(P>0.5).Conclusion:Antisocial personality traits can predict the aggressive behavior of juvenile offenders through their impulsiveness.Impulsivity is regulated by dark personality level between antisocial personality traits and aggressive behavior,and the low dark level group positively predicted impulsivity,the high dark subjects do not predict impulsiveness.
