This is a theoretical reflection on action-research and its contributions as a methodological approach to the expansion of knowledge production in Nursing. Besides the theoretical concepts of several authors on this methodology, we tried to identify, in the scientific production of Nursing, the applicability of the action-research in the investigations of the area. We observed that this method allows an interaction between the researcher and the object being researched, a relationship which is already established in the daily practice of the activities undertaken by nurses, because it allows the subjects (clients) to have voice and opportunity. In other words, it allows a dialogue which is open, participatory and reflective, assisting the individuals from a holistic point of view, always including them in an interaction with their families and the community, in addition to constantly seeking a positive transformation of this reality.
