Child psychopathic traits appear to be associated with negative outcomes. Despite the study of youth psychopathy often relying on multiple reporters (e.g., child, caregivers, teachers), there is limited insight into how much information these various sources contribute and moreover, how this information is integrated. The present study sought to address this gap in the literature by examining the magnitude of relationships between self- and other-reported youth psychopathy and negative outcomes (e.g., delinquency, aggression) using a meta-analytic approach. Results revealed a moderate association between psychopathic traits and negative outcomes. Moderator analyses showed a greater relationship for other- than self-reported psychopathy, although not to a substantive extent. Results further indicated the magnitude of the overall psychopathy-negative outcomes association was stronger for externalizing than internalizing outcomes. Study findings can inform improvements in the assessment of youth psychopathy across research and practice, in addition to advancing our understanding of the utility of psychopathic traits in the prediction of clinically relevant outcomes. This review also provides guidance for future multisource raters and source-specific information in the study of psychopathy in youth.

儿童精神病特征似乎与负面结果相关。尽管对青少年精神病的研究通常依赖于多个报告者（例如儿童、照顾者、教师），但对这些不同来源提供了多少信息以及如何整合这些信息的了解有限。本研究试图通过使用荟萃分析方法检查自我和其他人报告的青少年精神病与负面结果（例如犯罪、攻击性）之间关系的程度来解决文献中的这一空白。结果显示，精神病态特征与负面结果之间存在中度关联。主持人分析显示，与自我报告的精神病态相比，两者之间存在更大的关系，尽管程度不高。结果进一步表明，外化结果的整体精神病与负面结果的关联程度比内化结果更强。研究结果可以为研究和实践中青年精神病评估的改进提供信息，此外还可以增进我们对精神病特征在预测临床相关结果中的效用的理解。该综述还为未来的多源评估者和青年精神病研究中的特定源信息提供了指导。
