Psychopathy-related personality traits as well as platelet monoamine oxidase (MAO) activity and criminality from the age of 15 years were studied in a group of 68 male former juvenile delinquents and 32 control subjects. The former juvenile delinquents registered for crime as adults were found to have higher Psychopathy Check List (PCL) scores and lower platelet MAO activity than either juvenile delinquents who were not registered criminals from the age of 15 years or non-criminal controls. Although PCL scores and platelet MAC activity were unrelated, a configural frequency analysis showed a significant interaction. Individuals with PCL scores, low platelet MAO activity and persistent criminal behaviour constituted a significant "type'. Among the 27 former juvenile delinquents who developed persistent criminality, 21 subjects (78%) had PCL scores greater than 0 and low platelet MAO activity, while none of these persistent criminals were characterized by a combination of zero PCL score and high platelet MAO activity.
对一组68名男性前少年犯和32名对照对象进行了研究，涉及与精神病态相关的人格特质、血小板单胺氧化酶（MAO）活性以及15岁起的犯罪情况。结果发现，成年后登记犯罪的前少年犯比15岁起未登记为罪犯的少年犯或非犯罪对照对象具有更高的精神病态检查表（PCL）得分和更低的血小板MAO活性。虽然PCL得分与血小板MAO活性无关，但构型频率分析显示存在显著的交互作用。PCL得分高、血小板MAO活性低且有持续犯罪行为的个体构成了一个显著的“类型”。在27名发展为持续犯罪的前少年犯中，21名受试者（78%）的PCL得分大于0且血小板MAO活性低，而这些持续犯罪者中没有一人具有PCL得分为零且血小板MAO活性高的组合特征。
