Abstract
The aim of this paper is to reflect on the genesis, the theoretical foundation and the importance of action research as a strategy for psychological intervention. It is intended, from this resumption, to fulfill the demand of a researcher in psychology: define the fundamental of the emerging of action research and facilitate the scientific basis of psychological intervention supported by this working method. Action research can be epistemologically considered as a form of “qualitative” research, differentiating itself from traditional and positivist research methods, which are more connected to a reductionist approach of human and psychological “experimental” phenomenon and quantitatively controllable.
