Since the beginning of Social Work, the importance of research as a tool to achieve its objective has been stressed: social change based on the defense of human rights and social justice. However, a gap between research and professional practice persists. Given this situation that limits its capacity for transformation, Social Work has not remained static, but has sought ways to overcome it. This article presents the Communicative Methodology and its already demonstrated social impact, as a way to contribute to the reduction of the gap between research and practice. Although the first study based on it focused on the Roma people, it is currently being carried out in almost all the contexts in which Social Work intervenes. Given the importance of respecting the principles of Social Work to achieve its objectives, the article explores the fit of the Communicative Methodology in research in this discipline. For this, the principles and objectives of Social Work established by the IFSW are related to those of this methodology.
