Focus groups are now widely adopted in qualitative health and social resear
ch, and have been increasingly used as a data-collection technique in nursi
ng research. The focus group is not a new method, but its uses and procedur
es have been considerably revised in recent years. The aim of this paper is
to present an overview of the focus group as a research tool in social sci
ence literature, followed by a more considered discussion on the use of foc
us groups in contemporary critical social science. It draws on this work to
illustrate the potential of focus groups to address some of the political
issues in social research, in particular the balance of power between resea
rcher and researched, and the empowerment of under-represented groups. Adva
ntages of the method in connecting the researcher with group perspectives a
nd experiences that may be unexplored by other methods of data collection a
re discussed, and the 'collective conscience' is put forward as an appropri
ate resource in data analysis. It argues that the application of focus-grou
p techniques can build on experiences and principles of working with or par
ticipating in groups. Focus groups are particularly applicable to research
in nurse education, for involving diverse stakeholders in curriculum evalua
tion and development, and in ongoing appraisals of the student's perception
s of their experience, for which universities have tended to rely on survey
approaches and structured questionnaires. The article ends by drawing some
conclusions from the health and social research literature to inform nursi
ng education research using focus groups. (C) 2001 Harcourt Publishers Ltd.
