OBJECTIVE
Language development is important for children's success in life. Therefore, language is monitored by child health care professionals and parents, but a uniform set of milestones in language development is lacking. Our aim was to identify a set of clear and distinctive milestones that empirically reflect language development in children aged 1 to 6 years of age.
METHODS
We obtained a community-based sample of 1381 parents reporting on milestones derived from clinical signs and currently used language screening instruments. We used nonparametric Item Response Theory analysis to identify milestones belonging to one unidimensional scale.
RESULTS
Twenty-six milestones were excellently scalable (item H coefficients 0.62-0.90) and formed a strong scale (total H coefficient 0.83). The final set of identified milestones covered vocabulary, grammar, and communication, with an item ordering that holds for all children.
CONCLUSIONS
This unidimensional set of 26 clear and distinctive milestones reflects language development in young children and can be used as an instrument to monitor language development.
目的
语言发展对儿童生活的成功至关重要。因此，儿童保健专业人员和家长对语言进行监测，但缺乏统一的语言发展里程碑标准。我们的目的是确定一套清晰独特的里程碑，以实证反映 1 至 6 岁儿童的语言发展。
方法
我们从基于社区的 1381 名父母中获得了一个样本，报告了源自临床体征和当前使用的语言筛查工具的里程碑。我们使用非参数项目反应理论分析来确定属于一个单一维度量表的里程碑。
结果
26 个里程碑具有极好的可扩展性（项目 H 系数 0.62-0.90），并形成了一个强大的量表（总 H 系数为 0.83）。最终确定的里程碑集涵盖词汇、语法和交流，适用于所有儿童。
结论
这组 26 个清晰独特的里程碑构成了一个单一维度，反映了幼儿的语言发展，可以用作监测语言发展的工具。
