This article examines two outcomes of the transition to adulthood for youth who are involved with both the child protection and juvenile justice systems, known as dual-system youth. Data from a longitudinal study conducted in Quebec between 2017 and 2021 with 1136 youth in care suggest that dual-system youth are less likely to graduate from high school and more likely to experience housing instability and homelessness than are youth who have been in child protection alone. The article demonstrates that the differences between the two groups are far from anecdotal. The potential interactions of these results with the youth’s interpersonal support network are also examined. Finally, this article paints a bleaker picture of the situations dual-system youth experience during the transition to adulthood. It emphasizes the importance of focusing on the outcomes of the transition to adulthood to design socio-legal actions that can better prepare dual-system youth for this stage of their lives.

本文探讨了参与儿童保护和少年司法系统的青年（称为“双轨制青年”）向成年过渡的两个结果。 2017 年至 2021 年在魁北克省对 1136 名接受照料的青少年进行的纵向研究的数据表明，与单独接受儿童保护的青少年相比，双元制青少年高中毕业的可能性较小，而且更有可能经历住房不稳定和无家可归的情况。这篇文章表明，这两个群体之间的差异绝非偶然。还研究了这些结果与青少年人际支持网络的潜在相互作用。最后，本文描绘了双体制青年在向成年过渡过程中经历的更为黯淡的情景。它强调了关注向成年过渡的结果的重要性，以设计社会法律行动，以便更好地为双轨制青年的这一人生阶段做好准备。
