This chapter proposes a conceptual and methodological approach to the relationship: intervention-research from the Social Work, assuming the need to look at the tense relations between research and intervention, through a methodological perspective that includes the EpistemologicalTheoretical, the Political and the Methodical-Operational. That is, in the complex tensions existing between the place of enunciation of Social Work itself and its particular ways of understanding the world to transform it, from the particular perspective of phenomenology.
