This clinical focus article describes how to assess and when to target diverse, simple sentences as part of early language intervention.
The theoretical foundations and clinical motivations for assessing sentence diversity based on unique combinations of subjects and verbs are explained, followed by a description of how to compute the measure. Sentence diversity is then related to familiar developmental measures of lexical diversity, utterance length, and grammatical complexity in a sample of 40 typically developing toddlers at 30 months of age. Descriptive and correlational analyses are used to demonstrate how sentences become more diverse as utterances also become longer and more complex.
The ability to produce simple sentences with diverse subject-verb combinations is proposed as a general developmental expectation for toddlers at 30 months of age. All 40 children produced at least 10 different subject-verb combinations in 30 min of parent-toddler conversation. Sentence diversity is also associated with familiar developmental measures. Recommendations are provided for using the measure of sentence diversity to inform treatment planning and monitor progress for young children with language disorders.
本临床重点文章介绍了如何评估和针对不同的简单句进行目标设定，将其作为早期语言干预的一部分。
本文解释了基于主语和动词的独特组合来评估句子多样性的理论基础和临床动机，接着介绍了如何计算该测量方法。然后，在一个由 40 名 30 个月大的典型发展幼儿组成的样本中，将句子多样性与词汇多样性、话语长度和语法复杂性的常见发展性测量进行了关联。描述性和相关性分析用于证明随着话语变得更长、更复杂，句子也变得更加多样化。
提出了 30 个月大的幼儿能够用不同的主语-动词组合生成简单句子的能力是一种普遍的发展期望。所有 40 名儿童在 30 分钟的亲子对话中至少生成了 10 种不同的主语-动词组合。句子多样性也与常见的发展性测量相关。为了使用句子多样性的测量来为语言障碍儿童的治疗计划提供信息并监测进展，提出了一些建议。
