Education day on borderline personality disorder (BPD), including a transmission of current scientific knowledge on the disease. A dimensional understanding of BPD is delivered as well as disidentification of oneself to the symptoms of borderline personality disorder (Ducasse 2020 Eur Arch Psychiatry Clin Neurosci). The main objective is to evaluate the impact of borderline education day on self-stigma.

Borderline personality disorder defined as "a pattern of instability in interpersonal relationships, self-image and affects, and impulsiveness marked" concerns 4-6% of the general population. This is the emotional trouble the most associated with the occurence of suicide attempts (85% of these patients make multiple suicide attempts) and death by suicide (10% of these patients). This is a major public health problem.

A large number of patients with borderline personality disorder are not informed of their diagnosis. The main reasons are : the non-recognition of this disorder by health professionals, the belief that borderline personality disorder is a overly stigmatizing diagnosis , or preference to diagnose another disorder - that professionals think respond better to treatments and therefore be of a better prognosis.

Patients with borderline personality disorder often think themselves as "bad people" or the only people suffering from these symptoms. Thus, the ignorance of borderline personality disorder by patients leads to a basis of their altered sense of identity, perceived as defective or isolated. This generate a strong internalized stigma.

Many people diagnosed with borderline personality disorder receive no information about this disorder while psychoeducation has shown its effectiveness in severe psychiatric disorders, including the disorder of borderline personality, by reducing the negative repercussions psychiatric pathology. Moreover, the education of patients suffering from self-stigma makes it possible to in the face of negative beliefs around the disease and the acquisition of knowledge about the disorder and how to deal with it reduces self-stigma in bipolar patients. However, the propensity to feel shame - the stigmatization of oneself as worthless - is strongest in borderline personality disorder compared to all psychiatric disorders and most associated with the occurence of suicidal behaviors. In recommendations with good clinical practice, the investigator propose within the sector a day of education on borderline personality disorder including a transmission of current scientific knowledge on the illness, a dimensional understanding of the disorder, and the dis-identification of self to the symptoms of borderline personality disorder. The investigator hypothesize that this day of psychoeducation makes it possible to decrease self-stigma, which could be a mediator in reducing negative repercussions of borderline pathology.
