Starting from the research project Contributions of phenomenology and existential psychology to psychopathology, some questions and reflections are presented on the concrete contributions that phenomenology and existential psychology make to the understanding of the problems that psychopathology faces today. For this, the different phenomenological perspectives are explored in order to describe methodological and epistemological considerations in relation to the study of psychopathology at a theoretical level; together with this, theoretical components of existential psychology are addressed with the aim of exposing their position regarding mental illness, in addition to the articulation of said position with phenomenology. Based on the above, this article proposes as a conclusion some of the problems that psychopathology is facing and a synthesis of the importance and relevance of the aforementioned disciplines for the resolution or understanding of these problems.
