A diary is a recording of events over time by an individual to document experiences, feelings, or behavior patterns. Diaries are also called logs or journals and have been used since the 1950s to collect data for research from a variety of populations including children, the acute and chronically ill, pregnant women, and the elderly. A diary, which allows recording shortly after an event, is thought to be more accurate than obtaining the information through recall during an interview. In addition, the reporting level of incidents is higher, and one tends to capture the participant's immediate perception of situations. The diary technique gives nurse researchers a means to obtain data on topics of particular interest within nursing that have not been accessible by other means.
