“Is all the stuff about neurons necessary?” The development of lay summaries to disseminate findings from the Newcastle Cognitive Function after Stroke (COGFAST) study

Plain English SummaryWhy did we do this study?It can be difficult for scientists to communicate their research findings to the public. This is partly due to the complexity of translating scientific language into words that the public understand. Further, it may be hard for the public to find out about and locate information about research studies. We aimed to adapt some scientific articles about the links between dementia and stroke into lay summaries to be displayed online for the general public.How did we do it?We collaborated with five people from a volunteer organisation, VOICENorth. They took part in two group discussions about studies reporting on the link between dementia and stroke, and selected four studies to translate into lay summaries and display on a website. We discussed the layout and language of the summaries and made adaptations to make them more understandable to the general public.What did we find?We were able to work with members of the public to translate research findings into lay summaries suitable for a general audience. We made changes to language and layout including the use of ‘question and answer’ style layouts, the addition of a reference list of scientific terms, and removing certain words.What does this mean?Working with members of the public is a realistic way to create resources that improve the accessibility of research findings to the wider public.AbstractBackground Scientific research is often poorly understood by the general public and difficult for them to access. This presents a major barrier to disseminating and translating research findings. Stroke and dementia are both major public health issues, and research has shown lifestyle measures help to prevent them. This project aimed to select a series of studies from the Newcastle Cognitive Function after Stroke cohort (COGFAST) and create lay summaries comprehensible and accessible to the public. Methods We used a focus group format to collaborate with five members of the public to review COGFAST studies, prioritise those of most interest to the wider public, and modify the language and layout of the selected lay summaries. Focus groups were audio-taped and the team used the data to make iterative amendments, as suggested by members of the public, to the summaries and to a research website. We calculated the Flesch reading ease and Flesch-Kincaid grade level for each summary before and after the changes were made. Results In total, we worked with five members of the public in two focus groups to examine draft lay summaries, created by researchers, relating to eight COGFAST studies. Members of the public prioritised four COGFAST lay summaries according to the importance of the topic to the general public. We made a series of revisions to the summaries including the use of ‘question and answer’ style layouts, the addition of a glossary, and the exclusion of scientific jargon. Group discussion highlighted that lay summaries should be engaging, concise and comprehensible. We incorporated suggestions from members of the public into the design of a study website to display the summaries. The application of existing quantitative tools to estimate readability resulted in an apparently paradoxical increase in complexity of the lay summaries following the changes made. Conclusion This study supports previous literature demonstrating challenges in creating generic guidelines for researchers to create lay summaries. Existing quantitative metrics to assess readability may be inappropriate for assessing scientific lay summaries. We have shown it is feasible and successful to involve members of the public to create lay summaries to communicate the findings of complex scientific research.
