青少年黑暗三人格的网络结构:基于高斯图和有向无环图的探索

The Network Structure of the Dark Triad in Adolescents:An Exploration Based on Gaussian and Directed Acyclic Graphs

目的:探索青少年黑暗三人格的网络结构。方法:用黑暗十二条量表对十所学校的4200名中小学生进行调查,基于图形LASSO法构建高斯图模型,接着使用有向无环图构建条目之间的潜在因果模型。结果:所有条目组成一个单一的三维网络,马基雅维利主义与精神病态联系紧密,自恋置于网络边缘。核心条目为“我习惯于欺骗别人以达到自己的目的”和“我倾向于利用别人以达到自己的目的”。贝叶斯网络发现“我习惯于欺骗别人以达到自己的目的”是马基雅维利主义及整个网络的驱动点。结论:尽管马基雅维利主义与精神病态存在概念重叠但两者仍隶属不同构念;自恋在黑暗三人格中具有特殊性;两种网络方法都表明欺骗与利用在青少年黑暗三人格网络中发挥着重要作用。

Objective:Based on network psychometrics to explore the network structure of the dark triad of adolescents.Methods:The Dark Triad Dirty Dozen Scale was conducted on 4200 students from ten primary/middle schools.We employed two complementary methods.Results:The results showed that all of the items formed a single network consisting of three dimensions.Machiavellianism and psychopathy were located in close proximity,and narcissism was placed on the edge of the network.“I have used deceit or lied to get my way”and“I tend to exploit others toward my own end”were highly central in the network.The Bayesian network found that“I have used deceit or lied to get my way”was the driving point of Machiavellianism and the entire network.Conclusion:Although the concepts of Machiavellianism and psychopathy overlap,they still belong to different constructs;Narcissism has particularity in dark triad;Both network computing approaches pointing to Machiavellianism play an important role in the dark triad network system.
