BPD Test: 9 DSM-5-TR Borderline Personality Disorder Criteria + Scoring

The BPD test on this page is a 9-item screener mapped one-to-one to the DSM-5-TR criteria for Borderline Personality Disorder. A positive screen is 5 or more of the 9 criteria.

The screener covers the symptom clusters clinicians look for during a structured BPD assessment: emotional dysregulation, unstable relationships, identity disturbance, impulsivity, and intense fear of abandonment. It is educational, not diagnostic — confirm BPD with a licensed clinician using a structured interview (e.g. SCID-5-PD or IPDE).

Screening tools are not appropriate for emergency crisis situations. If you or someone you know is at immediate risk, see our crisis resources for lines by country.

What is borderline personality disorder?

Borderline Personality Disorder (BPD), also known as Emotionally Unstable Personality Disorder (EUPD) in some countries, is a complex mental health condition characterized by profound emotional dysregulation, unstable and intense relationships, identity disturbance, impulsivity, and intense fear of abandonment. In a community survey of 34,653 American adults, 5.9% met DSM-IV criteria for BPD ^[2].

BPD has historically been underdiagnosed, misdiagnosed as bipolar disorder, or undertreated due to diagnostic complexity and stigma.

Psychotherapies tailored to BPD reduce symptom severity compared with treatment as usual. Dialectical behaviour therapy (DBT) is the most studied, the subject of about a third of trials in a Cochrane review, and was more effective than treatment as usual on BPD severity, self-harm and psychosocial functioning, on low-quality evidence ^[3].

Because BPD presentations vary enormously between individuals — any combination of 5 of 9 criteria is possible — treatment planning benefits from systematic outcome monitoring alongside psychotherapy.

What does the BPD test measure?

The BPD test asks about the nine DSM-5-TR criteria for borderline personality disorder, one item per criterion.

Nine DSM-5-TR BPD criteria

DSM-5-TR requires ≥5 of these 9 criteria, present across a variety of contexts, representing a pervasive and persistent pattern (not limited to episodes of another disorder):

• Frantic Efforts to Avoid Abandonment — real or imagined fears of abandonment, including extreme reactions to perceived rejection
• Unstable Relationships — a pattern of intense, unstable interpersonal relationships alternating between idealization and devaluation
• Identity Disturbance — markedly and persistently unstable self-image or sense of self
• Impulsivity — impulsive behaviour in at least two potentially self-damaging areas (e.g., spending, substance use, reckless driving, binge eating)
• Suicidal/Self-Harm Behaviour — recurrent suicidal behaviour, gestures, threats, or self-mutilating behaviour
• Affective Instability — marked reactivity of mood with intense episodic dysphoria, irritability, or anxiety
• Chronic Emptiness — chronic feelings of emptiness
• Intense Anger — inappropriate, intense anger or difficulty controlling anger
• Dissociation/Paranoia — transient, stress-related paranoid ideation or severe dissociative symptoms

How do you give the BPD test?

The BPD test is a brief self-report screener. Rate how much each description applies to you over the past year. This screener is not a diagnosis, it requires clinical evaluation to confirm.

How do you score and interpret the BPD test?

A response is endorsed when an individual identifies with a given criterion as a persistent, pervasive pattern rather than a transient reaction. Each endorsed criterion carries equal weight; there is no overall severity score, only a count.

• Positive screen. Endorsing 5 or more of the 9 items means a full diagnostic evaluation by a trained clinician is warranted.
• Negative screen. Endorsing fewer than 5 items does not rule out BPD, but suggests current borderline features are below the clinical threshold.

Confirm any positive screen with a structured diagnostic interview such as the SCID-5-PD or the IPDE.

Screening vs diagnosis: what's the difference?

BPD Screening

• Brief self-report questionnaires (MSI-BPD, PDQ-4+)
• Quick identification of high-risk individuals
• Determines who needs full assessment
• Takes 2–5 minutes — the first step that flags potential cases

BPD Diagnosis

• Thorough clinical interview (SCID-5-PD)
• Comprehensive evaluation by a trained clinician
• Definitive diagnostic determination
• Takes 45–90 minutes — the criterion standard that confirms diagnosis

Standardized screening gives the clinician a structured starting point. It does not replace the clinical interview, but it can prompt a closer look at features that an unstructured conversation may miss.

Validated BPD screening tools

Several brief self-report questionnaires have been validated against structured diagnostic interviews for BPD. The table below summarizes the most commonly used tools, their formats, and their validated cutoffs. Note that sensitivity and specificity figures reflect the specific samples studied; all positive screens require clinical confirmation.

MSI-BPD (McLean screener for BPD)

The MSI-BPD is one of the most studied BPD screening tools in research and clinical settings. Its 10 items screen for borderline personality disorder as defined in DSM-IV.

• Adults. In the original validation, a cutoff of ≥7 out of 10 gave sensitivity of 81% and specificity of 85% in a psychiatric treatment-seeking sample; for adults aged 25 or younger, accuracy was higher ^[1].
• Adolescents. In a French adolescent sample, the original cutoff of ≥7 kept high specificity (0.95) but lower sensitivity (0.63); a cutoff of ≥5 gave sensitivity 0.87 and specificity 0.85 ^[4].

Screening tools identify individuals who need further evaluation, not a definitive diagnosis: always follow positive screens with a full diagnostic interview.

PDQ-4+ BPD scale

The Personality Diagnostic Questionnaire-4+ (PDQ-4+) includes a BPD subscale covering criteria that map to DSM borderline diagnostic criteria. It is a brief self-report questionnaire. A clinically meaningful threshold for the isolated BPD subscale has not been established in primary indexed literature reviewed for this page; clinicians should interpret results in the context of a full clinical assessment rather than relying on a standalone cutoff.

BPFS-C (children and adolescents)

The Borderline Personality Features Scale for Children (BPFS-C) is a self-report questionnaire for borderline personality features in school-age children. In its development study, 400 fourth to sixth graders were followed over a year: the scale showed construct validity, and its scores were related to indicators of borderline pathology beyond depressive symptoms ^[5].

Unlike the MSI-BPD, the BPFS-C does not rely on a single validated total-score cutoff; clinicians interpret profiles alongside clinical interview. Early identification of borderline features enables preventive intervention before personality patterns become entrenched.

Psychometric properties

This 9-item criteria screener has not itself been validated against a diagnostic interview, and its ≥5 threshold mirrors the DSM-5-TR diagnostic rule rather than a published screening cutoff. The closest validated self-report screen is the MSI-BPD:

• Original validation. 200 adults aged 18 to 59 with treatment histories completed the MSI-BPD and were interviewed, blind to the results, with the BPD module of the Diagnostic Interview for DSM-IV Personality Disorders. A cutoff of 7 or more of 10 items gave sensitivity of 0.81 and specificity of 0.85; in the 63 participants aged 25 or younger, sensitivity was 0.90 and specificity 0.93 ^[1].
• Adolescents. In 84 adolescents from psychiatric centres and 85 matched controls, the French MSI-BPD showed excellent internal consistency (α = 0.87) and an area under the curve of 0.93 against the SIDP-IV interview; the optimal cutoff was 5 or more (sensitivity 0.87, specificity 0.85) ^[4].

Limitations

• Screening, not diagnosis. A positive screen flags the need for a structured interview such as the SCID-5-PD or IPDE; it cannot confirm BPD.
• Unvalidated threshold. The ≥5 count on this page follows the DSM-5-TR rule and has not been validated as a self-report cutoff.
• Self-report bias. Endorsement depends on insight and current mood; transient reactions can be mistaken for a persistent, pervasive pattern.
• Sample dependence. Published sensitivity and specificity for the MSI-BPD come from psychiatric treatment-seeking samples and may differ in community or primary care settings.
• Not for crises. Screening tools are not appropriate in an emergency; use crisis resources instead.

BPD in adolescents

While personality is still developing during adolescence, DSM-5-TR allows BPD diagnosis in adolescents when features have been present for at least one year and are pervasive across contexts. Timely intervention may prevent full syndrome development and improve long-term outcomes.

Use age-appropriate measures like the BPFS-C, avoid premature labelling, but address clinically significant borderline features promptly with evidence-based interventions. An adjusted MSI-BPD cutoff of ≥5 (rather than ≥7) improved sensitivity in an adolescent clinical sample ^[4].

BPD and personality disorder outcome tracking

Comprehensive outcome monitoring for BPD typically includes multiple domains tracked across therapy. Commonly used measures include:

• ZAN-BPD (Zanarini Rating Scale for BPD) — clinician-rated, 9 items covering affective, cognitive, impulsive, and interpersonal domains; the criterion measure in many RCTs
• DERS (Difficulties in Emotion Regulation Scale) — self-report measure of emotion regulation deficits, a core DBT treatment target
• DBT diary cards — weekly self-monitoring of emotions, urges, behaviours, and skill use; a core component of standard DBT
• PHQ-9 — tracks depressive symptoms, which frequently co-occur with BPD and respond to DBT
• GAD-7 — tracks anxiety symptoms, another common comorbidity in BPD populations

Integrating these measures into DBT programmes, intensive outpatient (IOP) settings, and residential treatment supports measurement-based care for personality disorders.
