About

Borderline Personality Disorder (BPD) is a common psychiatric disorder occurring in 2 to 6% of the population. 70% of patients with BPD do at least one Suicide Attempt (SA) in their lives. It makes BPD the most related to SA condition.

Negative interpersonal events are among the main stressor inducing a SA. Patients with BPD are characterized by emotional dysregulation, impulsivity (repeated parasuicidal and suicidal behaviors), and instability in interpersonal relationships. The feeling of shame related to this psychiatric disorder could be one of the causes of the high SA rate. In this study, patients with BPD will be follow-up during 5 years.

The main objective is to study the propensity to feel shame as a predictor of SA.

This include:

• Study of shame propensity as a predictive factor of suicidal behavior - Identify homogeneous subgroups of patients with BPD based on SA, and overall functioning.
• Identify biological markers predicting SA
• Identify predictive and protective treatments (pharmacological and psychotherapeutic) for SA
