This study aims at identifying predictors of suicidal behaviors in depressed subjects.
Investigators will first compare demographic, clinical, and biological features of depressed
recent suicide attempters (within one week) and depressed subjects without lifetime history
of suicide attempt. Baseline risk factors for suicide will be used to predict the risk of
attempting suicide during a one year follow-up. A thorough evaluation of these patients will
allow to identify the factors associated with suicidal risk and develop a simplified risk
score that could be used in clinical settings to improve our practice.
