Purpose: The purpose of this article was to describe feminism and to propose the integration of a feminist method into qualitative nursing methodology in order to expand the body of nursing knowledge. Method: The world view of feminism including philosophy, epistemology and methodology was outlined, and a feminist grounded theory and feminist ethnography were suggested as a way of strengthening nursing research methodology using literature review. Results: Four different philosophical perspectives of feminism, that is, liberal feminism, radical feminism, Marxist feminism, and social feminism were described. Also epistemological perspectives including feminist empiricism, feminist standpoint, and postmodem feminism, were explained and were related to the methodology and methods of feminism. To enhance the strengths of nursing research within the feminist perspectives, feminist grounded theory and feminist ethnography were exemplified in the paradigm of qualitative nursing research. Conclusion: This paper suggested that incorporation of feminist approaches within nursing is a valuable attempt to expand the body of nursing knowledge and to enhance the quality of nursing care services by rectifying male-oriented knowledge and by empowering women in the care of other people as well as themselves.
