Diary studies
Diary studies is a research method that collects qualitative information by having participants record entries about their everyday lives in a log, diary or journal about the activity or experience being studied. This collection of data uses a longitudinal technique, meaning participants are studied over a period of time. This research tool, although not being able to provide results as detailed as a true field study, can still offer a vast amount of contextual information without the costs of a true field study. Diary studies are also known as experience sampling or ecological momentary assessment (EMA) methodology. Traditionally diary studies involved participants keeping a written diary of events.
