Implicit and Explicit Assessment of Suicide Risk
A study testing Implicit Attitude Test in people with Implicit Association Test and Suicide, run by Centre Hospitalier Universitaire, Amiens at 1 site in France.
Trial 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. Read more about this study

About this study
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Implicit Attitude TestOther
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.
| Study group | Role | What they receive |
|---|---|---|
| Patient with explicit suicidal ideation and suicide attempt | Experimental | Not described Receives: Other: Implicit Attitude Test |
| Patient with explicit suicidal ideation without suicide attempt | Experimental | Not described Receives: Other: Implicit Attitude Test |
| Patient without explicit suicidal ideation | Active comparator | Not described Receives: Other: Implicit Attitude Test |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: one year
