Improving the Readability of Dementia Information Documents Using ChatGPT

There is much information available on dementia, but information may not be written at an appropriate level for a lay reader. One aim of the CoDESIGN project is to simplify information available for those who have lower levels of literacy. We investigate the potential to simplify documents to reflect the literacy abilities of the reader. We report on the ability of ChatGPT to modify documents to such target reading levels while retaining the accuracy and completeness of the documents, while avoiding the introduction of errors. Results suggest that human supervision is required before documents can be made available to readers.
