This article focuses on the advantages and difficulties encountered by the researchers when using this methodology. It is also centered on the participant's experience of the research and the potential benefits that may be encountered. Issues discussed include setting the duration of the diary and maintaining the motivation of participants, the type of data collected, and the language used by participants.
