In this study we examined the consistency of life-course child maltreatment trajectories and youth offending links across birth cohorts. In so doing we demonstrated the value of replication studies for maltreatment research. We applied the methodology of Stewart et al. (2008) and linked population-based (1990 birth cohort) child protection and youth justice administrative data from Queensland, Australia. We performed a group based trajectory analysis to identify distinct maltreatment trajectory groups distinguishable by maltreatment timing and frequency across the life-course. We explored group-based youth offending outcomes with consideration of variations in maltreatment chronicity, timing, and frequency, multi-type maltreatment, gender and race (Indigenous Australian versus non-Indigenous Australian youths). To determine the consistency of maltreatment trajectories and offending links across cohorts (1983/84 versus 1990) we compared our results with those of Stewart et al. (2008). Consistent with Stewart et al. (2008): (1) We identified six distinct maltreatment trajectory groups; (2) Trajectory groups characterised by chronic maltreatment and/or adolescent maltreatment had the largest proportion of young offenders; and (3) Maltreatment frequency commonly peaked at transition points. Extending beyond Stewart et al. (2008) we noted considerable overlap between maltreatment dimensions and a potential impact of race and multi-type maltreatment on maltreatment and offending links. We endorse replication studies as a valuable tool to advance child maltreatment policy and practice and recommend further research on interactions between maltreatment dimensions, gender, race, and youth offending.
在这项研究中，我们考察了儿童期虐待轨迹的一致性以及跨出生队列的青年犯罪之间的联系。这样做，我们展示了复制研究对于虐待研究的价值。我们应用了 Stewart 等人（2008）的方法，并链接了澳大利亚昆士兰州基于人群的（1990 年出生队列）儿童保护和青年司法行政数据。我们进行了基于群组的轨迹分析，以确定在整个生命周期中通过虐待发生时间和频率可区分的不同虐待轨迹群组。我们考虑了虐待的慢性、发生时间和频率、多种类型的虐待、性别和种族（澳大利亚原住民与非原住民青年）的变化，探讨了基于群组的青年犯罪结果。为了确定跨队列（1983/84 年与 1990 年）虐待轨迹和犯罪联系的一致性，我们将我们的结果与 Stewart 等人（2008）的结果进行了比较。与 Stewart 等人（2008）一致：（1）我们确定了六个不同的虐待轨迹群组；（2）具有慢性虐待和/或青少年期虐待特征的轨迹群组中，青年罪犯的比例最大；（3）虐待频率通常在过渡点达到峰值。超出 Stewart 等人（2008）的范围，我们注意到虐待维度之间存在相当大的重叠，以及种族和多种类型的虐待对虐待和犯罪联系的潜在影响。我们认可复制研究是推进儿童虐待政策和实践的有价值工具，并建议进一步研究虐待维度、性别、种族和青年犯罪之间的相互作用。
