About this trial

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.

Treatments tested in this trial

  • Implicit Attitude Test

    Other intervention

    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.

Treatment groups

108 Participants
are divided into 3 treatment groups
Group A: Patient with explicit suicidal ideation and suicide attemptExperimental treatment 1 intervention
Group B: Patient with explicit suicidal ideation without suicide attemptExperimental treatment 1 intervention
Group C: Patient without explicit suicidal ideationActive comparator 1 intervention

Variation of IAT score betwenn the 3 groups

IAT is Implicit Attitude Test The IAT is a brief computer-administered test that uses people's reaction times when classifying semantic stimuli to measure the automatic mental associations they hold about various topics, in this case, life and death/suicide. The death/suicide IAT will be administered and scored in keeping with standard IAT procedures. Response latencies for all trials were recorded and analyzed using the standard IAT scoring algorithm.
