The current study examined the longitudinal stability and invariance of psychopathic traits in a large community sample of male twins from ages 17 to 23. Participants were assessed across six years to gauge the stability and measurement invariance of the Minnesota Temperament Inventory (MTI), a Cleckley-based measure of psychopathic personality traits, and how family functioning and externalizing behavior were linked to these traits. A latent variable approach was used to model the structure of the MTI and provide a statistical test of measurement invariance across time. The results revealed support for invariance and moderate to strong stability of the MTI factors, which showed significant associations with the external correlates in late adolescence but not early adulthood.
本研究考察了17至23岁男性双胞胎的大型社区样本中精神病态特质的纵向稳定性和不变性。在六年时间里对参与者进行评估,以衡量明尼苏达气质量表(MTI)的稳定性和测量不变性,该量表是基于克莱克利的精神病态人格特质测量工具,同时考察家庭功能和外化行为与这些特质之间的联系。采用潜在变量方法对MTI的结构进行建模,并对跨时间的测量不变性进行统计检验。结果显示支持MTI因子的不变性和中度至高度稳定性,这些因子在青春期后期与外部相关因素存在显著关联,但在成年早期则不然。
