Abstract

Aphasia is an acquired language impairment caused by damage in the regions of the brain that support language. The Main Concept Analysis (MCA; Kong, 2016b) is a published formal assessment battery that allows the quantification of the presence, accuracy, completeness, and efficiency of content in spoken discourse produced by persons with aphasia (PWA). It utilizes a sequential picture description task (with four sets of pictures) for language sample elicitation. The MCA results can also be used clinically for targeting appropriate interventions of aphasic output. The purpose of this research is to develop a Spanish adaptation of the MCA (i.e., Span-MCA) by establishing normative data based on native unimpaired speakers of Spanish from four different dialect origins (Central American Caribbean, Andean-Pacific, Mexican, and Central-Southern Peninsular regions). A total of 91 unimpaired participants that consisted of different age groups, education levels, and dialect origins were recruited to establish four sets of dialect-specific norms and scoring criteria of Span-MCA, including target main concepts and corresponding lexical items related to the picture sets. The Span-MCA was also applied to one pilot native Spanish PWA. The normative data suggested that speakers who were younger or with a higher level of education levels produced significantly more accurate and complete main concepts in their spoken discourse. The application of Span-MCA to the pilot native Spanish PWA successfully identified impaired performance, as compared to the dialectally-sensitive norms established in this study. This study highlighted the clinical value of Span-MCA as a supplement to evaluate spoken discourse and target intervention by speech-language pathologists and related healthcare practitioners.
西班牙语版主概念分析(Span-MCA)用于量化神经源性受损口语话语的方言敏感规范
失语症是一种后天性语言障碍,由大脑中支持语言的区域受损引起。主概念分析(MCA;Kong,2016b)是一个已发表的正式评估组,允许量化失语症患者(PWA)口语话语中内容的存在性、准确性、完整性和效率。它利用顺序图片描述任务(有四组图片)进行语言样本抽取。MCA结果也可用于临床上针对失语症输出的适当干预。本研究的目的是通过建立基于来自四个不同方言来源(中美洲加勒比地区、安第斯太平洋地区、墨西哥和中南半岛地区)的西班牙语母语未受影响者的规范性数据,开发对MCA的西班牙语改编(即Span-MCA)。共招募了91名未受影响的参与者,他们包括不同的年龄组、教育水平和方言起源,以建立四套针对方言的Span MCA规范和评分标准,包括目标主要概念和与图片集相关的相应词汇。Span MCA也应用于一个试点的西班牙本土PWA。规范性数据表明,年龄较小或受教育程度较高的演讲者在口语中产生了更准确、更完整的主要概念。与本研究中建立的方言敏感规范相比,Span MCA在试点母语西班牙语PWA中的应用成功地确定了受损的表现。这项研究强调了Span MCA作为评估言语病理学家和相关医疗从业者的口语话语和目标干预的补充的临床价值。
