医療関連文書のリーダビリティ指標に関する一考察

抄録

This paper is the survey and discussion report about the readability indices for Japanese medical documents. The survey targets are medicine documents of “package insert” and “Kusuri no Shiori”. “Kusuri no Shiori” is a collection of documents aimed to read easier for patients. We compared those documents with the same medicines, using our readability indices (i.e., jFRE, jFKG, jARI, jCLI, jSMOG), which are adapted to both English and Japanese documents by the variable replacement method. The result of evaluate experiment showed that the almost documents of “Kusuri no Shiori” were easier than the others. Furthermore, some of jFRE calculated from “package insert” were not satisfied the difficulty criterion of FRE for life insurance policies, but all of jFRE calculated from “Kusuri no Shiori” were satisfied the criterion. Therefore, it was suggested that our proposed method is able to be used for ensuring readability in Japanese medical documents as same as English version (i.e., FRE).
