目的：文献中普遍存在的共识是，临床医生在临床环境中难以量化话语水平的表现。核心词典分析作为一种解决临床医生面临的困难的替代工具，最近得到了人们的关注。虽然已有研究表明核心词汇测量是评估失语症患者话语的有效手段，但核心词汇测量的心理测量特性尚未得到研究。本研究的目的是：(a)通过使用微语言和宏观语言测量来检验并发效度；(b)通过最少的训练来证明评判员在没有转录的情况下的相互信度。方法本研究采用pwa中收集的均匀语言样本。同时效度是通过将核心词汇测试与微语言和宏观语言测试进行对比来评估的。为了提高评分者的信度，4名评分者使用核心词典检查表对10个pwa的录音话语样本进行评分。结果核心词汇量与微语言量和宏语言量呈显著相关。4个评价者间获得了可接受的信度。结论score词汇分析可用于测量语篇水平的词语检索障碍。这也可能是一种可行的解决方案，因为它减少了话语评估的准备工作。
PurposeGeneral agreement exists in the literature that clinicians struggle with quantifying discourse-level performance in clinical settings. Core lexicon analysis has gained recent attention as an alternative tool that may address difficulties that clinicians face. Although previous studies have demonstrated that core lexicon measures are an efficient means of assessing discourse in persons with aphasia (PWAs), the psychometric properties of core lexicon measures have yet to be investigated. The purpose of this study was (a) to examine the concurrent validity by using microlinguistic and macrolinguistic measures and (b) to demonstrate interrater reliability without transcription by raters with minimal training.MethodEleven language samples collected from PWAs were used in this study. Concurrent validity was assessed by correlating performance on the core lexicon measure with microlinguistic and macrolinguistic measures. For interrater reliability, 4 raters used the core lexicon checklists to score audio-recorded discourse samples from 10 PWAs.ResultsThe core lexicon measures significantly correlated with microlinguistic and macrolinguistic measures. Acceptable interrater reliability was obtained among the 4 raters.ConclusionsCore lexicon analysis is potentially useful for measuring word retrieval impairments at the discourse level. It may also be a feasible solution because it reduces the amount of preparatory work for discourse assessment.
