Psychopathy and trauma exposure are robustly associated with youth conduct problems, but the interrelation of these constructs is unclear. The objective of the present study is to examine psychopathy mediation effects related to trauma events and trauma reactions and juvenile delinquency, conduct disorder, crime seriousness, and proactive overt aggression outcomes. The sample consisted of N =388 (M = 16.01 years, SD = 1.03 years, age range = 13–18 years) male youths from Portugal. Path analysis procedures revealed that psychopathy partially mediates the relation between trauma events and the juvenile delinquency, conduct disorder, crime seriousness outcomes, and fully mediates the relation between trauma events and the proactive overt aggression outcome. Trauma reactions have no direct significant effect on psychopathy, and psychopathy does not mediate the relation between trauma reactions and the examined outcomes. Research on trauma and adverse childhood experiences should encompass both events and reactions to those events as they have differential associations with psychopathy and externalizing outcomes. Trauma-informed service, supervision, and treatment is essential for understanding antisocial development and psychological maladjustment among youth.

心理疾病和外伤暴露与青少年行为问题密切相关，但这些结构的相互关系尚不清楚。本研究的目的是研究与创伤事件和创伤反应以及青少年犯罪，行为失调，犯罪严重性和主动的公开侵略结果有关的心理疾病调解作用。样本由N = 388（M = 16.01年，SD= 1.03岁，年龄范围= 13-18岁）来自葡萄牙的男性青年。路径分析程序显示，精神病部分地介导了创伤事件与青少年犯罪，品行障碍，犯罪严重程度结果之间的关系，并充分介导了创伤事件与主动的公开侵略结果之间的关系。创伤反应对精神病没有直接的显著作用，精神病不介导创伤反应与检查结果之间的关系。关于创伤和不利的儿童经历的研究应既包括事件，也包括对这些事件的反应，因为它们与精神病和外在化结果有着不同的关联。创伤知情的服务，监督和治疗对于理解年轻人的反社会发展和心理失调至关重要。
