The purpose of this study was to examine the relationship between picture naming performance and the ability to communicate the gist, or essential elements, of a story. We also sought to determine if this relationship varied according to Western Aphasia Battery-Revised (WAB-R; Kertesz, 2007) aphasia subtype.
Demographic information, test scores, and transcripts of 258 individuals with aphasia completing 3 narrative tasks were retrieved from the AphasiaBank database. Narratives were subjected to a main concept analysis to determine gist production. A correlation analysis was used to investigate the relationship between naming scores and main concept production for the whole group of persons with aphasia and for WAB-R subtypes separately.
We found strong correlations between naming test scores and narrative gist production for the large sample of persons with aphasia. However, the strength of the correlations varied by WAB-R subtype.
Picture naming may accurately predict gist production for individuals with Broca's and Wernicke's aphasia, but not for other WAB-R subtypes. Given the current reprioritization of outcome measurement, picture naming may not be an appropriate surrogate measure for functional communication for all persons with aphasia.
本研究旨在探讨图片命名表现与传达故事要点或基本要素的能力之间的关系。我们还试图确定这种关系是否因西方失语症成套测验修订版（WAB-R；Kertesz，2007）失语症亚型而有所不同。
从失语症银行数据库中检索了 258 名失语症患者的人口统计学信息、测试分数和 3 项叙事任务的转录本。对叙述进行了主要概念分析，以确定要点的产生。采用相关分析来调查整个失语症患者组以及 WAB-R 亚型组的命名得分与主要概念产生之间的关系。
我们发现，在大量失语症患者中，命名测试得分与叙事要点产生之间存在很强的相关性。然而，相关性的强度因 WAB-R 亚型而异。
图片命名可能可以准确预测 Broca 氏和 Wernicke 氏失语症患者的要点产生，但不能预测其他 WAB-R 亚型。鉴于当前对结果测量的重新优先排序，图片命名可能不是所有失语症患者功能交流的合适替代测量指标。
