Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The study compares the effectiveness of two psychotherapies for borderline personality disorder, mentalization-based therapy and a modified version of Linehan's dialectical behavior therapy, in a retrospective naturalistic study of patients with at least one cluster B personality disorder who have undergone either treatment. The scarcity of data on cluster B personality disorders and on the comparison between MBT and DBT further highlights the necessity of a naturalistic study like ours to examine both aspects and bring research closer to the clinical setting. Based on clinical observations, the investigators believe that there will be no statistically significant difference between either treatment.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Mentalization-based Treatment
Participants who have been oriented to the mentalization-based treatment among the clinical adult population with a cluster B personality disorder.
Mentalization-based Treatment
An empirically-validated intervention for personality disorders based on the attachment theory and on knowledge from developmental psychology and cognitive neuroscience (Bateman and Fonagy, 2004). Patients assist psychoeducative group meetings beforehand, along with a pretreatment of four to six individual meetings (over four to eight weeks), followed by bi-weekly individual follow-ups and weekly group follow-ups. The treatment lasts two years. Patients have an assessment meeting with their individual therapist and one of the group therapists at the end of each session. Psychiatric follow-up appointments are on an as-needed basis and every patient has a treatment contract with specific and measurable treatment objectives.
Dialectical Behavior Therapy-inspired Treatment
Participants who have been oriented to the dialectical behavior therapy-inspired treatment among the clinical adult population with a cluster B personality disorder.
Dialectical Behavior Therapy-inspired Treatment
A psychotherapy developed by M. Linehan for patients with borderline personality disorder that combines cognitive behavioral therapy techniques (emotional regulation, practical exercises) with Buddhist meditation principles (stress tolerance, acceptance, open-mindedness) (Linehan, M. M. \& Dimeff, L., 2001). As opposed to Linehan's model, individual meetings are bi-weekly, no emergency phone service is offered, the mindful meditation module is reorganized into life habits modules, and every module includes mindfulness exercises. Patients assist psychoeducative group meetings beforehand, along with a pre-treatment of 4-6 individual meetings (over 4-8 weeks), followed by bi-weekly individual follow-ups and weekly group follow-ups. The treatment lasts one year, but can be extended to two years for eligible patients who are interested. Psychiatric follow-up appointments are on an as-needed basis. Every every patient has a treatment contract with specific and measurable treatment objectives.
