Brief Summary

Suicidal behaviors (SB) are a major health problem in France:10,000 suicides and 220,000 suicide attempts every year. SB management is therefore a major public health issue. Recently, investigators have demonstrated the interest of acceptance and commitment therapy (ACT) as an add-on treatment to reduce intensity and severity of suicidal ideation in depressed patients having a history of suicide attempt within previous year (i.e actual SB disorder according to the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5)). Based on structural and functional findings, it is admitted orbitofrontal and ventral prefrontal cortices play a role in suicidal vulnerability. Interestingly, previous functional MRI (fMRI) studies have also reported the modulation of these regions by ACT in subjects suffering from chronic pain. fMRI could thus be an interesting tool to identify biomarkers of SB and its improvement by ACT.

The aim of study is to investigate neural biomarkers of ACT efficiency in patients with SB disorder. Patients having a history of SB within previous year were randomized in an ACT program (21 patients) or relaxation program (21 patients) during 7 weeks. Before and after the completion of the group, they performed 3 tasks during fMRI: implicit emotional visualization, Cyberball game, motivational task Investigators will compare cerebral activations between groups, between pre and post intervention as well as measure baseline cerebral activations associated with improvement of suicidal ideation during follow up.

Detailed Description

42 patients having a history of suicide attempt within the year preceding inclusion have been recruited.

First visit or inclusion (within 2 weeks preceding the beginning of the program): clinical, biological assessment and fMRI acquisition Second visit (within 2 weeks +/- 1 week following completion of the program): clinical assessment and fMRI acquisition Third visit (within 3 months +/- 2 weeks following completion of the program): clinical assessment
