Adverse childhood experiences (ACEs) have long been recognized for negatively influencing individual outcomes such that each additional ACE exposure increases the risk for negative health and behavioral outcomes. Little is known, however, about how the more recent accumulation of ACEs occurring in follow-up periods influence global functioning considering the past accumulation of ACEs reported at baseline by justice-involved adolescents. Participants were 851 adolescents who completed the Northwestern Juvenile Project (NJP), a longitudinal survey. OLS regression models were used to examine the influence of follow-up and baseline ACEs on the functional impairment of youth. Results indicate that both follow-up and baseline ACEs were associated with worse functioning over time with baseline ACEs demonstrating a greater effect. This study highlights the importance of assessing accumulations of ACEs over time for adolescents in the juvenile justice system and considering how youth of different characteristics and experiences may differently encounter functional impairment. Implications for offering trauma-informed services to disrupt the effects of adversity on adolescents’ functioning are discussed.

长期以来，不良儿童经历（ACE）一直被认为会对个人结局产生负面影响，因此，每增加一次ACE暴露都会增加负面健康和行为结局的风险。但是，考虑到司法介入的青少年过去在基线时所报告的ACE的累积量，在随访期内发生的ACE的较近累积量如何影响全球功能知之甚少。参与调查的851名青少年完成了西北青少年项目（NJP），这是一项纵向调查。OLS回归模型用于检查随访和基线ACE对青少年功能障碍的影响。结果表明，随着时间的推移，随访和基线ACE均与较差的功能有关，基线ACE则显示出更大的效果。这项研究强调了评估青少年司法系统中随着时间的推移ACE积累的重要性，并考虑了具有不同特征和经历的青年如何可能不同地遇到功能障碍的重要性。讨论了提供创伤知情服务以破坏逆境对青少年功能的影响。
