An evaluation of the use of diaries in a study of medication in later life

This paper is based upon our experience of commissioning diaries to be kept by research subjects. First the paper reviews some previous research based on diaries, then it outlines the aims of our research and the method of data collection. Then the paper goes on to evaluate the design and use of a diary that participants in our research completed. In particular we consider the ways in which the diary may have biased our sample, caused the participants difficulties and generated poor data. There is also a discussion on how it may have affected behaviour and on the ethical issues that are raised by commissioned diaries. In conclusion, observations are made about the strengths and weaknesses of diaries as an investigative tool with a wider applicability. The diary proved particularly revealing and we recommend that other researchers consider diaries as a method of investigating everyday life.
