What this trial studies

This clinical trial investigates the effectiveness of Mentalization-Based Treatment (MBT) compared to bona fide treatments (BFT) such as psychodynamic or cognitive-behavioral psychotherapy for patients with Borderline Personality Disorder (BPD) in Germany. The study aims to determine if MBT can more effectively reduce crisis events, including non-suicidal self-injury and suicide attempts, while also assessing its impact on overall functioning, symptom severity, and cost-effectiveness. Participants will be monitored for changes in their mental health and quality of life over the course of the treatment. This randomized-controlled trial addresses a significant gap in existing research on outpatient MBT in Germany.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients with Borderline Personality Disorder, potentially reducing self-harm and improving overall mental health outcomes.

How similar studies have gone: While there is limited research on MBT in outpatient settings in Germany, similar studies in other regions have shown promising results for MBT in treating BPD.
