Proposition analysis of the discourse of persons with aphasia has a long history, yielding important advancements in our understanding of communication impairments in this population. Recently, discourse measures have been considered primary outcome measures, and multiple calls have been made for improved psychometric properties of discourse measures.
To advance the use of discourse analysis in persons with aphasia by providing Main Concept Analysis checklists and descriptive statistics for healthy control performance on the analysis for the Cat in the Tree and Refused Umbrella narrative tasks utilized in the AphasiaBank database protocol.
METHODS & PROCEDURES: Ninety-two control transcripts, stratified into four age groups (20-39 years; 40-59; 60-79; 80+), were downloaded from the AphasiaBank database. Relevant concepts were identified, and those spoken by at least one-third of the control sample were considered to be a main concept. A multi-level coding system was used to determine the accuracy and completeness of the main concepts produced by control speakers.
OUTCOMES & RESULTS: Main concept checklists for two discourse tasks are provided. Descriptive statistics are reported and examined to assist readers with evaluation of the normative data.
These checklists provide clinicians and researchers with a tool to reliably assess the discourse of persons with aphasia. They also help address the gap in available psychometric data with which to compare persons with aphasia to healthy controls.
失语症患者话语的命题分析有着悠久的历史，在我们对这一人群沟通障碍的理解方面取得了重要进展。最近，话语测量已被视为主要结局测量指标，并且多次呼吁改善话语测量的心理测量特性。
通过提供主要概念分析清单以及失语症数据库协议中所使用的“树上的猫”和“拒绝雨伞”叙述任务分析中健康对照表现的描述性统计数据，推进失语症患者话语分析的应用。
从失语症数据库下载了92份对照转录本，分为四个年龄组（20 - 39岁；40 - 59岁；60 - 79岁；80岁及以上）。确定了相关概念，至少三分之一的对照样本说出的概念被视为主要概念。使用多层次编码系统来确定对照说话者产生的主要概念的准确性和完整性。
提供了两个话语任务的主要概念清单。报告并检查了描述性统计数据，以帮助读者评估规范数据。
这些清单为临床医生和研究人员提供了一种可靠评估失语症患者话语的工具。它们还有助于弥补现有心理测量数据方面的差距，以便将失语症患者与健康对照进行比较。
