Articles are prepared using evidence-based sources and clinical editorial standards.
If you experience intense mood swings, fear of abandonment, unstable relationships, or impulsive actions, you are not alone. The MSI-BPD (McLean Screening Instrument) is a widely used 10-item yes/no questionnaire for borderline personality disorder traits. On LuriaLab you can take the free borderline personality test online anonymously and get instant scoring with guidance.
What is MSI-BPD?
MSI-BPD screens areas such as unstable self-image, fear of rejection, impulsivity, suicidal thoughts, chronic emptiness, and anger difficulties. Developed at McLean Hospital (Zanarini et al.) and used in clinics worldwide.
How to interpret your score
A common screening threshold is 7 or more “yes” answers. This is not a diagnosis — it signals that a full evaluation by a qualified clinician may be helpful. LuriaLab shows your count and explanation automatically.
MSI-BPD vs BSL-23
MSI-BPD is a quick yes/no screen. BSL-23 measures symptom severity over the past week in more detail. Both tools complement each other on LuriaLab.
Related screenings
Borderline traits often overlap with anxiety, depression, and dissociation. Consider GAD-7 or DES-II if those symptoms are prominent.
