The Short-Term MBT Project

Status Completed

Clinical Trial Summary

The study will evaluate the benefitial and harmful effects of short-term (20 weeks) compared to long-term (14 months) mentalization-based therapy for outpatients with subthreshold or diagnosed borderline personality disorder.

Clinical Trial Description

Psychotherapy for borderline personality disorder is often lengthy and resource-intensive. Mentalization-based therapy is an example of an evidence-based treatment that currently has empirical support as an 18-months outpatient program for borderline personality disorder. However, this duration is rarely available, and the long and costly treatment combined with a highly prevalent disorder result in insufficient access to evidence-based care. The trial is an investigator-initiated, single-centre, assessor-blinded, randomized clinical superiority trial of short-term (20 weeks) compared to long-term (14 months) outpatient mentalization-based therapy for borderline personality disorder or subthreshold borderline personality disorder. Participants will be recruited from the Outpatient Clinic for Personality Disorders at Stolpegaard Psychotherapy Centre, Mental Health Services, Capital Region of Denmark. Participants will be assessed at trial intake using the Mini International Neuropsychiatric Interview and the Structured Clinical Interview for DSM-5 Personality Disorders. Participants will be included if they meet a minimum of four DSM-5 criteria for borderline personality disorder. Participants will be assessed blind to treatment allocation at baseline, and at 8, 16, and 24 months after randomization. The primary outcome is severity of borderline symptomatology assessed using the Zanarini Rating Scale for Borderline Personality Disorder interview. Secondary outcomes include self-harm incidents, functional impairment (Work and Social Adjustment Scale), quality of life (Short-Form Health Survey), and global functioning (Global Assessment of Functioning scale). Psychiatric symptoms (Symptom Checklist 90) will be included as an exploratory outcome. Measures of personality functioning, attachment, group alliance, borderline symptoms and mentalization skills will be included as predictor and mediator variables. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
