Focus groups are important tools for assessing markets, making public policy and researching applied science. The use of focus groups can enable us to gather large volumes of data in short periods of time. The need for focus groups, because of the economical and efficient way in which they generate information, has grown recently in nursing. Focus groups can be used among different groups within a population, including teenagers, healthy adults, elderly people, patients and nurses. The manner in which they are used, however, must be adjusted to take account of the characteristics of each group. This article discusses the preparation, implementation, analysis and reporting of the use of focus groups among elderly people. It was important to observe the elderly subjects' physical and psychological states, work and rest habits, and interaction, and carefully arrange the detail of each group in accordance with the findings of such observation. This article is intended to enable the experience of using focus groups among the elderly to be shared with other researchers.
