This paper aims to clarify the nature of the discourse of older adults recorded using the Coimagination Method, a conversation support method that aims to activate cognitive functions in older adults from the perspective of decontextualization, as the first step of a study analyzing whether the decontextualization perspective can be applied as an indicator of language ability to enhance the cognitive functioning of older adults. For analysis, we used the taxonomy of Rhetorical Unit Analysis, a discourse analysis method within the framework of Systemic Functional Linguistics. Rhetorical Unit Analysis provides information on the rhetorical function and decontextualization index of each unit of analysis, the "message" (a clause). We analyzed three sessions of the Coimagination Method discourse on two different themes. The results showed that the rhetorical functions used for each theme were different. Furthermore, the rhetorical functions used for each theme were commonly observed in multiple sessions across multiple individuals in both the "topic presentation" and "question-and-answer" parts of the sessions. In addition, it was found that some rhetorical functions that were not dependent on the theme were used in the "topic presentation," and that some rhetorical functions that were not often used in the "topic presentation" were used in the "question-and-answer" part.
