研究目的核心词汇测量在研究中受到越来越多的关注。他们的目的是提供一个临床医生友好的手段来量化话语中的单词检索能力的基础上正常预期的话语生产特定的话语启发任务。到目前为止，不同的标准已被用于开发核心词汇的研究小组的措施。在追求心理鲁棒measure.AimsThis研究的统计指导的必要性已经被公认为是调查准确测量的最佳标准。具体而言，我们专注于两个标准（frequencyvs.百分比），以前被用于开发的核心词汇measures.MethodCore词汇的措施，包括五个不同的检查表，按单词类（动词，名词，形容词，副词，和功能词）和开发的两个标准被施加到语言样本470认知健康的成年人。在话语水平上的词检索能力的表现被建模为一个潜变量的基础上观察到的比例生产的核心词汇项目在两个不同的核心词汇measures使用结构方程modeling.ResultsResults结果表明，这两个标准的核心词汇的措施捕捉词检索能力的话语。更大的剩余方差被发现在核心词汇的措施建立的百分比标准相比，建立的频率标准。这表明，基于百分比标准的措施更受测量errors.ConclusionsThe研究结果提供的证据表明，频率标准是更好地用于核心名词，动词，形容词和副词的核心词汇措施的发展，但不是功能词。然而，我们的研究结果仅限于核心词汇的措施，基于语言样本引起的无字图画书。由于语言样本的质量和数量的差异，这可能不容易应用于其他使用不同语篇启发任务的核心词汇测量。理想情况下，同样的方法应该被复制，以评估在开发核心词汇测量时各自标准的适当性。补充材料https：doi.org/10.23641/asha.20304144
PurposeCore lexicon measures have received growing attention in research. They are intended to provide clinicians with a clinician-friendly means to quantify word retrieval ability in discourse based on normal expectations of discourse production for specific discourse elicitation tasks. To date, different criteria have been used to develop core lexicon measures by groups of researchers. The need for statistical guidance in pursuit of the psychologically robust measure has been recognized.AimsThis study was to investigate the best criterion for accurate measurement. Specifically, we focused on two criteria (frequencyvs.percentage) that have previously been used for the development of core lexicon measures.MethodCore lexicon measures consisting of five different checklists by word class (verbs, nouns, adjectives, adverbs, and function words) and developed by the two criteria were applied to language samples produced by 470 cognitively healthy adults. Performance in word retrieval ability at the discourse level was modeled as a latent variable based on the observed proportions of the production of core lexicon items in two different sets of core lexicon measures using structural equation modeling.ResultsResults indicated that both criterion for core lexicon measures capture word retrieval ability in discourse. Greater residual variances were found in the core lexicon measure established by the percentage criterion compared to the one established by the frequency criterion. This indicates that the measure based on the percentage criterion is more affected by measurement errors.ConclusionsThe findings provide evidence that the frequency criterion is better to use for the development of core lexicon measures for core nouns, verbs, adjectives, and adverbs, but not for function words. However, our findings are limited to core lexicon measures based on language samples elicited by wordless picture books. This may not be easily applied to other core lexicon measures that use different discourse elicitation tasks due to the difference in quality and quantity of language samples. Ideally, the same approach should be replicated to evaluate the appropriateness of respective criteria in the development of core lexicon measures.Supplemental Materialhttps://doi.org/10.23641/asha.20304144
