DIalectical Behavior Therapy and Acceptance Commitment Therapy Short Program for BOrderLine persOnality Disorder

According to the World Health Organization 1 death by suicide occurs every 40 seconds, leading suicide prevention to one of the public health priority. Borderline personality disorder (BPD) is a common condition affecting 6% of the population. This disorder is characterized by unstable emotions, unstable mood, difficulties with relationship and feer of abandonment. BPD is also the psychopathology the most related to suicidal attempts. Indeed, up to 50% of the patients admitted to hospital after a suicide attempt are diagnosis with a BPD. Negative interpersonal events (events occurring between two people) are known as the main stressor that trigger a suicidal attempt. People with a BPD are highly sensitive to it. Unfortunately, patient care for this disorder is limited. Pharmacological strategies didn't show any efficacy and psychotherapies, although proven effective, are difficult to set up. As BPD is strongly related to suicidal attempts it appears to be a good model to study suicidal behavior. Thus, this study could improve knowledge in this field. Suicidal behavior in patients receiving the standard therapy (dialectic behavioural therapy: DBT) will be compared to patients receiving dialectical behavior therapy and acceptance commitment therapy (ACT). Clinical data reflecting how the participant is feeling will be collected as well.
