Predictors of Suicidal Behavior in Depression

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.
