Aphasia is a higher brain dysfunction that affects the production or comprehension of speech and the ability to read or write. The purpose of this research is to establish support guidelines based on a questionnaire survey and a language activity analysis of rehabilitation training so that volunteers can more easily assist disabled persons with aphasia. The focus of this study was the non-profit community-based intervention group Yokohama Aphasia Partner Group, which consists of members with aphasia, their families, speech-language-and-hearing therapists, psychiatric social workers, and volunteers. The following results were obtained. (1) Members with aphasia participate in the Partner Group because they can meet others with aphasia on a regular basis as well as participate in the aphasia rehabilitation program with the recovery of language functions. In addition to medical treatment, the community-based support, which improves the environment and other life contextual factors, is important for rehabilitation. (2) An individual with aphasia shows different language actions, and so an individually different support system in accordance with language activity is necessary.
