Brief Summary

Suicidal behavior (SB) is a major public health problem in France, with over 10,000 suicides (6th in the EU28) and 220,000 suicide attempts (SA) per year. These data seem underestimated by 20%. A large percentage of men (6%) and women (9%) in France made at least one lifetime SA. In addition, SBs are common among young people and are the second leading cause of death among 15-44 year-olds. The interaction of multiple factors in SB complicates the creation of predictive models. These are currently imprecise and prevent the development of consensual recommendations for the management of suicidal patients.

Most suicide attempters are evaluated in the emergency room where it is imperative to identify people with a high risk of relapse. Risk assessment is generally based on the experience of the practitioner who uses psychometric scales as support for clinical decisions. This assessment could be improved and supplemented by other sources of information. Thus, we aim to develop a short and specific tool that combines:

1. Neurocognitive measures carried out using computer software on domains strongly associated with SB: impulsivity, affective dysregulation, alterations in decision-making (risky choices), selective attention and verbal fluency.

2. Clinical and psychological assessment including the most predictive items of future SA: life events (environment) and personality traits (vulnerability). Suicide attempters will be assessed for SB and suicidal ideation in the emergency department. These measures will be repeated during a 12-month follow-up. We will use the data obtained to provide a more accurate measure of risk.

Detailed Description

Over 65 months, 5 emergency departments (Montpellier, Nimes, Uzès, Nice, Marseille) will recruit a total of 650 patients who attempted suicide.

* First visit: clinical and neuropsychological assessment

* Second and third visits at 6 and 12 months: assessment of SBs and suicidal relapse, clinical and neuropsychological assessment.

Arm && Interventions

Group	Intervention	Description
Neuropsychological battery tests	Neuropsychological battery tests	All participants performed the same evaluation: clinical and neuropsychological assessment. All of them are suicide attempters without psychotic features

Primary Outcome Measures

Name	Time	Method
Frequency of suicidal relapse according to aggressive impulsivity.	12 months	aggressive impulsivity will be assessed by the capacity to inhibit responses during a Continuous Performance Task (CPT)

Secondary Outcome Measures

Name	Time	Method
Characteristics of suicidal behaviors assessed by Columbia Suicide History Form and the Columbia Suicide Severity Rating Scale	12 months	We aim to identify predictive factors of the occurrence of suicidal behavior in a non-psychotic suicidal population, in order to develop a battery of short-term tests applicable to emergencies. This short term tests will allow to establish a multidimensional score for the prediction of the risk of relapse
Score of a short scale of suicidal risk assessment	12 months	We aim to identify predictive factors of the occurrence of suicidal behavior in a non-psychotic suicidal population, in order to develop a battery of short-term tests applicable to emergencies. This short term tests will allow to establish a multidimensional score for the prediction of the risk of relapse.
Intensity of suicidal ideation assessed by the Columbia Suicide Severity Rating Scale (C-SSRS)	12 months	We aim to identify predictive factors of the occurrence of suicidal behavior in a non-psychotic suicidal population, in order to develop a battery of short-term tests applicable to emergencies. This short term tests will allow to establish a multidimensional score for the prediction of the risk of relapse
