What this trial studies

The PEGASUS intervention aims to enhance treatment for individuals with emotionally unstable personality disorder, specifically borderline personality disorder, by integrating case management and family-based meetings into existing psychiatric care models in Denmark. This pilot trial will compare the PEGASUS intervention to standard treatment, assessing feasibility and acceptability through a randomized, assessor-blinded parallel-groups design. Participants will be evaluated at baseline and again nine months later to determine the effectiveness of the intervention in improving patient outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who are newly accepted into BPD treatment packages and can involve family members or close friends.

Not a fit: Patients with a primary diagnosis of schizophrenia or those with substance abuse issues may not benefit from this intervention.

Why it matters

Potential benefit: If successful, this intervention could significantly improve the quality of life and treatment outcomes for patients with borderline personality disorder.

How similar studies have performed: Previous studies have shown promise in integrating family involvement in the treatment of borderline personality disorder, suggesting that this approach may be beneficial.
