Intersubjective experience and phenomena addressed in psychiatric diagnosis are not available to standard scientific research. Many authors focused on intersubjectivity and the analysis of their work helps informing and clarifying how to address these facts.

This presentation aims to review the works of A. Shultz, C. Jaspers, F. Buytendijk, M. Heidegger, M Scheler (and others) on intersubjectivity in a phenomenological standpoint.

Approaching intersubjectivity from a phenomenological standpoint and its relations with current problems of psychiatric diagnosis and research.

Selective analysis of literature on phenomenological enquires of intersubjectivity in the field of Philosophy and Psychiatry

Research in psychopathology and psychiatry must neither treat intersubjective data as residuum nor try and reify data that resists reductionism and mechanistic explanations. Intersubjectivity is inherent to the meaning of psychopathological understanding and phenomena

There is need for new methods of enquire for many data in psychiatry. Researchers and clinicians must find new ways to deal with psychiatric objects and with relational data.
