Best practices in juvenile justice call for the individualized matching of services to assessed dynamic risk factors, with services delivered at sufficient dosage. However, prior work has largely ignored whether this recipe for recidivism reduction is as effective for adolescents with extensive traumatic exposure as it is for those without. The current study leverages a statewide sample of 1,666 juveniles released from residential placement (84.6% male, 59.8% Black, 11.9% Hispanic). We examine the associations of individual-level service matching and achieving dosage targets established by Lipsey’s Standardized Program Evaluation Protocol (SPEP) during residential placement with changes in dynamic risk during placement and recidivism post-release among juveniles with extensive adverse childhood experiences (ACE) exposure and those without. Results demonstrate heightened traumatic exposure is related to smaller reductions in dynamic risk and to an increased probability of reoffending, but that youth receiving matched services coupled with adequate dosage leads to greater treatment progress (dynamic risk reduction) and lower recidivism post-release for both low-ACE and high-ACE youth. Implications for juvenile justice practice and policy are discussed.

少年司法的最佳做法要求将服务与评估的动态风险因素进行个性化匹配，并以足够的剂量提供服务。但是，先前的工作在很大程度上忽略了这种降低累犯率的方法对于遭受大量创伤的青少年是否和没有遭受创伤的青少年一样有效。当前的研究利用了全州从居住场所释放的1,666名青少年样本（男性为84.6％，黑人为59.8％，西班牙裔为11.9％）。我们研究了在儿童安置期间和不良儿童经历广泛暴露的青少年中，Lipsey的标准化计划评估协议（SPEP）建立的个人级别服务匹配和达到剂量目标与居住期间安置的动态风险之间的关联，以及安置和累犯后释放中的动态风险之间的关联。和那些没有。结果表明，创伤暴露的增加与动态风险的降低程度较小以及再次犯罪的可能性增加有关，但接受匹配服务的青年人加上适当的剂量可导致更大的治疗进展（动态风险降低）和较低的两性患者释放后的复发率-ACE和高级ACE青年。讨论了对少年司法实践和政策的影响。
