The present study examined whether a sample of 214 (52.8% male, M age = 15.76, SD = 1.29) institutionalized adolescents could be classified into subgroups based on psychopathic traits. Confirmatory Factor Analyses revealed a relationship between the subscales of the Youth Psychopathic traits Inventory (YPI) and the three latent constructs of the original model on which it is based. Latent Class Analyses showed that adolescents showing psychopathic traits could be classified into three subgroups. The first group showed low scores on the grandiose/manipulative dimension, the callous/unemotional dimension, and the impulsive/irresponsible dimension (normal group). The second group scored moderate on the grandiose/manipulative dimension and the callous/unemotional dimension and high on the impulsive/irresponsible dimension (impulsive, non-psychopathic-like group). The third group scored high on all three dimensions (psychopathy-like group). The findings revealed that the impulsive, non-psychopathic like group scored significantly higher on internalizing problem behavior compared to the normal group, while the psychopathy-like and the impulsive, non-psychopathic-like group both scored higher on externalizing problem behavior compared to the normal group. Based on a self-report delinquency measure, it appeared that the psychopathy-like group had the highest delinquency rates, except for vandalism. Both the impulsive and psychopathy-like group had the highest scores on the use of soft drugs.
本研究考察了 214 名（52.8%为男性，M 年龄=15.76，SD=1.29）被收容的青少年是否可以根据精神病态特征分为亚组。验证性因子分析表明，青少年心理病态特征量表（YPI）的分量表与该量表所基于的原始模型的三个潜在结构之间存在关系。潜在类别分析表明，表现出精神病态特征的青少年可以分为三个亚组。第一组在浮夸/操纵维度、无情/无情感维度和冲动/不负责任维度上得分较低（正常组）。第二组在浮夸/操纵维度和无情/无情感维度上得分中等，在冲动/不负责任维度上得分较高（冲动、非精神病态样组）。第三组在所有三个维度上的得分都较高（精神病态样组）。研究结果表明，冲动、非精神病态样组的内化问题行为得分明显高于正常组，而精神病态样组和冲动、非精神病态样组的外化问题行为得分均高于正常组。基于自我报告的犯罪行为衡量标准，似乎精神病态样组的犯罪率最高，除了故意破坏行为。冲动组和精神病态样组在使用软毒品方面的得分最高。
