What this test measures
The nine features clinicians look at, in plain language
Borderline personality is one of the most misunderstood and stigmatized terms in mental health. This screening maps to the nine criteria a clinician actually considers, so a result can be a starting point for an informed conversation rather than a label.
The DSM borderline criteria
The nine features that define BPD: fear of abandonment, unstable relationships, identity disturbance, impulsivity, self-harm or suicidal behavior, mood swings, emptiness, intense anger, and stress-related paranoia or dissociation.
Brief, validated screen
Ten yes or no items modeled on the MSI-BPD, the short screening instrument researchers developed to flag who might benefit from a fuller assessment. A high count is a prompt, not a conclusion.
A treatable, human picture
BPD responds well to therapies like DBT, and many people see lasting improvement. This result is framed to reduce shame and point toward effective help, not to put a stigmatizing word on who you are.

How we built this test
Methodology & sources
The ten questions are modeled on the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD), developed by Zanarini and colleagues as a brief screen built around the nine DSM diagnostic criteria for BPD. Each item is reworded to stay faithful to the original meaning while reading in plain, non-clinical language. In the validation study, a cutoff of seven or more positive answers best balanced sensitivity and specificity for identifying people who may meet criteria and would benefit from a full diagnostic evaluation.
This test is provided for education and self-reflection. A screening cannot diagnose a personality disorder. Many of these experiences, such as fear of abandonment or strong emotions, exist on a continuum and show up in people without BPD, especially during stressful or painful periods. Only a trained clinician can assess BPD, through interview and history over time. We deliberately frame results around traits and next steps rather than identity.

Common questions
Borderline Personality (BPD) Test FAQ
What is a borderline personality (BPD) test?
It is a short, research-based screening informed by the MSI-BPD, a validated tool built around the nine clinical criteria for borderline personality disorder. It counts how many of those features you recognize in yourself. A higher count can suggest that a full assessment is worth considering, but it is a screening tool, not a diagnosis.
What score suggests I should seek an assessment?
In the validation research, seven or more positive answers out of ten best identified people who might meet criteria for BPD and would benefit from a professional evaluation. Scoring below that does not rule anything out, and scoring at or above it does not mean you have BPD. It simply suggests a conversation with a clinician could be useful.
Does a high score mean I have BPD?
No. Many of these experiences are part of being human and become more intense during stress, grief, or other conditions like depression, PTSD, or ADHD. BPD can only be assessed by a trained clinician over time. A high screen is a reason to ask, not an answer.
Can BPD be treated?
Yes, and this matters. BPD has some of the most encouraging outcomes in mental health. Dialectical behavior therapy (DBT) and other structured therapies have strong evidence, and long-term studies show most people improve substantially. The term is often used carelessly as an insult, which is unfair to a treatable, human experience.
Is this test really confidential?
Yes. It runs entirely in your browser. Your answers are never sent to a server, never stored, and never linked to you. No account is needed, and the optional PDF is generated on your own device.
