This free, private BPD self-test is based on the MSI-BPD (McLean Screening Instrument for Borderline Personality Disorder), a validated screening questionnaire clinicians use. It asks ten yes-or-no questions about experiences over time, takes about two minutes, and stays entirely on your device. It is a screening tool, not a diagnosis.
BPD Self-Test
A brief screening based on the MSI-BPD. Takes about two minutes.
This is a screening tool, not a diagnosis. It can help you understand your experiences, but only a clinician can diagnose borderline personality disorder. Your answers stay on your device — nothing is saved or sent. Answer each question about how you have felt over time, not just today.
Instrument: MSI-BPD, McLean Screening Instrument for Borderline Personality Disorder (Zanarini et al., 2003), a public-domain screening scale. If you are in crisis, call or text 988 anytime. Sacramento Mental Health treats adults 18 and older.
How to Read Your Score
The MSI-BPD counts how many of the ten items you answer yes. A total of 7 or more is the cut-point commonly used to suggest that a full evaluation for BPD is worthwhile. The table below summarizes the ranges.
| Score (0–10) | What It Suggests |
|---|---|
| 0–6 | Below the usual screening threshold for BPD |
| 7–10 | A positive screen; a comprehensive evaluation is recommended |
Is This a Diagnosis?
No. A positive screen does not mean you definitely have BPD, and a lower score does not rule it out. Only a clinician can diagnose borderline personality disorder, through a comprehensive assessment that looks at your full history and how long these patterns have been present. A screen like this is a useful starting point, not the final word.
What to Do Next
If your result suggests BPD, or if these experiences are interfering with your relationships or daily life regardless of the score, the next step is to talk with a professional. BPD is highly treatable, especially with dialectical behavior therapy. To understand the condition and the options, see our guide to BPD treatment, or call (916) 527-9606 to discuss coverage and payment options.

Is this BPD test accurate?
The MSI-BPD is a validated screening tool that performs well at flagging people who may have BPD. It is designed to identify who should be evaluated further, not to diagnose. A positive screen is a strong reason to talk with a clinician.
What is a positive score on the MSI-BPD?
A total of 7 or more yes answers out of ten is the commonly used cut-point suggesting that a full evaluation for BPD is worthwhile. A lower score does not rule BPD out if these patterns are causing significant distress.
Are my answers private?
Yes. This screen runs entirely in your browser. Your answers are not saved, sent, or stored anywhere, and no personal information is collected.
What should I do if I screen positive?
A positive screen means it is worth talking with a professional. The next step is a comprehensive assessment, which can confirm whether BPD is present and guide treatment. BPD is very treatable, and reaching out is a strong first move.
