To investigate the predictive validity of psychopathic personality traits (assessed with the revised psychopathy checklist, PCL-R; Hare, 1991) for violent criminal recidivism among young offenders.
The relationship between PCL-R psychopathy and violent re-offending was studied in 98 young (M=18.40, range 15-20 years) violent and sex offenders subjected to forensic psychiatric evaluation in Sweden during 1988-95. Subjects were followed during detainment and for 24 months in the community to first reconviction for a violent offence.
We found a modest but significant association between PCL-R scores and violent recidivism, almost exclusively accounted for by behavioural criteria. Among 13 possible confounders tested, conduct disorder before age 15 and a young age at first conviction eliminated the relationship between psychopathy and violent recidivism in pair-wise logistic regression models.
PCL-R psychopathy may be a less valid predictor for violent criminal recidivism among severe youthful offenders than among adult offenders.
探讨精神病态人格特质（用修订后的精神病态量表，即PCL-R评估；黑尔，1991年）对青少年罪犯暴力犯罪再犯的预测效度。
对1988年至1995年期间在瑞典接受法医精神病学评估的98名年轻（平均年龄18.40岁，范围15至20岁）暴力和性犯罪者，研究PCL-R精神病态与暴力再犯之间的关系。在拘留期间以及在社区中随访24个月，直至首次因暴力犯罪被再次定罪。
我们发现PCL-R分数与暴力再犯之间存在适度但显著的关联，几乎完全由行为标准所解释。在测试的13个可能的混杂因素中，15岁前的品行障碍和首次定罪时的年轻年龄在成对逻辑回归模型中消除了精神病态与暴力再犯之间的关系。
与成年罪犯相比，PCL-R精神病态对严重青少年罪犯暴力犯罪再犯的预测效度可能较低。
