The benefits and limitations of the application of poststructuralist in nursing research are discussed. The debate concerning the use of poststructuralist theory in feminist research is drawn on to argue a divergence between a deconstructionist poststructuralism and nursing aims. It is argued that there are strong parallels between nursing and social movements such as feminism. The reasons why many feminist and nursing researchers have been attracted to poststructuralist theory are explored, as are the criticisms of poststructuralism as an inadequate, even reactionary theory. It is argued that poststructuralism is useful for examining or deconstructing existing discourse and practice, but incompatible and inadequate for research which aims to develop or change such discourses or practices.
