“…main verb and other relevant pieces of essential information), which are then quantified in terms of the output's presence, accuracy, and completeness of information, as well as efficiency of the output. The MCA has now been adopted, validated, and/or translated in US English (Kong, Whiteside, & Bargmann, 2015), Irish English (Kong, Ross, & Pettigrew, 2012), Mandarin Chinese spoken in Taiwan (Kong & Yeh, 2015) and mainland China (Gao, Kong, & Lau, 2016), Cantonese Chinese (Kong, 2009(Kong, , 2011, Japanese (Yazu, Yoshino, & Kong, 2018), and Korean (Kong, 2018). Although the same picture stimuli are used across these different language versions, each of them contains a set of culturally appropriate lexical items and geographically-specific main concepts, obtained through careful analyses of normative samples from native speakers of different countries, that are related to characters depicted by the stimuli for subsequent scoring of performance.…”

“…Results from the above-mentioned MCA studies have revealed the MCA to be suitable for assessing the presence and degree of aphasia in adult speakers suffering from stroke, dementia, and/or acquired brain injuries. The good to excellent inter-and intra-rater reliability of the tool (e.g., Kong, 2018) as well as its applicability to monitor changes or stable discourse performance (e.g., Kong, 2011) further indicated the MCA to be a useful clinical battery for assessing high-level functioning PWA. A study by Rivera, Hirst, and Edmonds (2018) has applied the scoring principles and criteria of MCA to examine the impacts of language dominance on unimpaired Spanish/ English bilingual speakers' production of main concepts in spoken discourse.…”

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.
