Abstract：
UNASSIGNED: This systematic review and multilevel meta-analysis examines the accuracy of sentence repetition (SR) tasks in distinguishing between typically developing (TD) children and children with developmental language disorder (DLD). It explores variation in the way that SR tasks are administered and/or evaluated and examines whether variability in the reported ability of SR to detect DLD is related to these differences.
UNASSIGNED: Four databases were searched to identify studies that had used an SR task on groups of monolingual children with DLD and TD children. Searches produced 3,459 articles, of which, after screening, 66 were included in the systematic review. A multilevel meta-analysis was then conducted using 46 of these studies. Multiple preregistered subgroup analyses were conducted in order to explore the sources of heterogeneity.
UNASSIGNED: The systematic review found a great deal of methodological variation, with studies spanning 19 languages, 39 SR tasks, and four main methods of production scoring. There was also variation in study design, with different sampling (clinical and population sampling) and matching (age and language matching) methods. The overall meta-analysis found that, on average, TD children outperformed children with DLD on the SR tasks by 2.08 SDs. Subgroup analyses found that effect size only varied as a function of the matching method and language of the task.
UNASSIGNED: Our results indicate that SR tasks can distinguish children with DLD from both age- and language-matched samples of TD children. The usefulness of SR appears robust to most kinds of task and study variation.

摘要：
■这项系统评价和多层次荟萃分析研究了句子重复（SR）任务在区分典型发育（TD）儿童和发育性语言障碍（DLD）儿童方面的准确性。它探讨了SR任务的管理和/或评估方式的变化，并检查了SR检测DLD的报告能力的变化是否与这些差异有关。
■搜索了四个数据库，以确定对患有DLD和TD儿童的单语儿童组使用SR任务的研究。搜索产生了3,459篇文章，其中，筛选后,66个被纳入系统评价。然后使用其中的46项研究进行了多水平荟萃分析。进行了多个预先注册的亚组分析，以探索异质性的来源。
■系统评价发现了大量的方法差异，研究涉及19种语言，39个SR任务，和四种主要的生产评分方法。研究设计也有变化，采用不同的抽样(临床抽样和人群抽样)和匹配(年龄和语言匹配)方法。整体荟萃分析发现，平均而言,TD儿童在SR任务上的表现优于DLD儿童2.08SDs。亚组分析发现，效果大小仅随任务的匹配方法和语言而变化。
■我们的结果表明，SR任务可以将具有DLD的儿童与年龄和语言匹配的TD儿童样本区分开。SR的有用性对于大多数类型的任务和研究变化似乎是稳健的。
