[Conceptual and methodological issues involved in the research field of diagnostic reasoning]

The psychopathological field is crossed by dilemmas that put in question its methodological, conceptual and philosophical filiations. Since the early works of Ey and Jaspers until recent work of Berrios it has been in question the position psychopathology has in the field of medicine in general, and in the field of psychiatry in particular, especially if it should follow the principles of natural science or if it has an autonomous position between them. This debate has led to two opposing positions facing two different models of psychopathology: the biomedical model and the socio-constructionist model. In this work it is proposed to review the scope and difficulties involved in each model following two central axes: diagnostic reasoning and mental illness conceptual problem. Later, as a synthesis of the analysis proposed they are identified central concepts of each model that could allow the development of a hybrid model in psychopathology; in between them the comprehensive framework employed in symptoms recognition and the social component that characterizes it are highlighted. As a conclusion, these concepts are proposed as central aspects for conceptual and methodological clarification of the research field of diagnostic reasoning in psychopathology.
