Abstract(s) :

(Anglais) Clinical reasoning is one of the clinician's weapons, if not the best. Its understanding, teaching and evaluation are of great interest to health professionals. Nursing and medical sciences have paid much attention to this concept from the cognitive side (De Alencastro et al., 2017; Pelaccia et al., 2010), but it has received very little attention from the processual and subjective perspective. In other words, little space has been given to the subjective experience of the clinician as a tool for understanding the processes involved in clinical reasoning. It is thanks to the mobilisation of clinical reasoning that the clinician will implement a multitude of mental activities - which are inter-influential - to establish links, elaborate hypotheses and propose therapeutic actions adapted to the situation. For this 8th edition of the QRMH congress, we will focus our attention on the emergence of hypotheses in clinical work. We will first propose an overview of the concept of hypothesis and its multiple facets. Then, we will explain how the Explicitation Interview (EI), an investigation tool created by Vermersch (1994), allows us to understand the processes (cognitive, emotional, mental and procedural) at work in the emergence of hypotheses in the clinician. Finally, we will conclude with three clinical illustrations of situations in which a clinical hypothesis emerges: in crisis intervention, during the first moments of the reception, and in a psychotherapy interview.
