Summary

In 2007 Nock \& Banaji developed a so-called implicit suicide risk measurement using a computer tool: the Implicit Association Test (IAT). This measurement, associated with traditional evaluations, makes it possible to better predict suicidal recurrence. In 2020, the Poitiers team of Tello was able to replicate these results on a French population. However, although a high IAT score predicts the onset of suicide at 1 year, there is no data on how this score changes over time nor even data concerning the measure's ability to differentiate a population with explicit suicidal ideation from a population without explicit suicidal ideation. The investigators therefore seek to demonstrate an evolution of implicit suicidal ideation over time by replicating the measurement at inclusion, at 6 months and at 12 months, for different patient profiles: Suicidal ideation vs No suicidal ideation and suicide attempt vs no suicide attempt. Patients will be recruited from the emergency-unit of CHU Amiens-Picardie and will take the suicide-IAT as well as various questionnaires.

Type	Name	Description
OTHER	Implicit Attitude Test	The IAT (Implicit Attitude Test) is a method of indirectly measuring the relative strength of associations between different concepts stored in memory based on reaction times on computer. The general idea behind this measure is that an individual will be much faster to categorize an object into a predetermined category, if this categorization is consistent with their own way of processing information.
