Previous research has provided robust evidence demonstrating that a notable proportion of youth become involved in both the child welfare (CW) system and the juvenile justice (JJ) system, a population often referred to as crossover youth. Prior work has identified a number of risk factors associated with crossing over between these systems. However, there are limitations to the extant literature, key among which is a lack of systematic attention to the influence of trauma exposure and posttraumatic sequelae on the crossover trajectory. In contrast, viewing this research through a trauma-informed lens promises to enhance our ability to integrate findings across studies and to derive theoretically derived hypotheses about underlying mechanisms which will better inform future research and the development of effective prevention and intervention efforts. Accordingly, the purpose of this article is to present a trauma-informed research agenda that would strengthen future research in the field. After providing a brief critique of the existing studies that has documented known risk factors associated with the crossover population, we outline ways in which future research could apply relevant theoretical trauma-informed approaches, including developmental traumatology, to further advance our knowledge of risk factors and mechanisms associated with the crossover trajectory. We conclude by discussing policy and system-wide implications related to the proposed research agenda.

先前的研究提供了有力的证据表明，相当一部分青年同时参与了儿童福利 (CW) 系统和少年司法 (JJ) 系统，这一群体通常被称为跨界青年。之前的工作已经确定了许多与这些系统之间的交叉相关的风险因素。然而，现有文献存在局限性，其中关键是缺乏对创伤暴露和创伤后遗症对交叉轨迹影响的系统关注。相比之下，从创伤知情的角度来看这项研究有望提高我们整合研究结果的能力，并从理论上推导出关于潜在机制的假设，这些假设将更好地为未来的研究和有效预防和干预工作的发展提供信息。因此，本文的目的是提出一个创伤知情的研究议程，以加强该领域未来的研究。在对记录了与交叉人群相关的已知风险因素的现有研究进行了简要评论之后，我们概述了未来研究可以应用相关理论创伤知情方法（包括发育创伤学）的方式，以进一步提高我们对风险因素和风险因素的认识。与交叉轨迹相关的机制。
