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).

Understanding BPD

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. BPD affects approximately 1.6% (general population epidemiological surveys, DSM-5) to 5.9% (community adult sample; Zanarini et al., 2011) of the population, and is among the most impairing and high-cost psychiatric conditions.

BPD has historically been underdiagnosed, misdiagnosed as bipolar disorder, or undertreated due to diagnostic complexity and stigma. Evidence-based psychotherapies have substantially improved outcomes: Dialectical Behavior Therapy (DBT) is the most extensively studied treatment for BPD, with DBT outperforming treatment-as-usual on BPD severity, self-harm, and psychosocial functioning across multiple RCTs (Storebø et al., 2020). 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.

BPD Symptom 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.

Endorsed Criteria

A response is endorsed when an individual identifies with a given criterion as a persistent, pervasive pattern rather than a transient reaction. On this screener, endorsing 5 or more of the 9 items constitutes a positive screen, indicating that a full diagnostic evaluation by a trained clinician is warranted. Endorsing fewer than 5 items is a negative screen — it does not rule out BPD, but suggests current borderline features are below the clinical threshold. Each endorsed criterion carries equal weight; there is no overall severity score, only a count. Confirm any positive screen with a structured diagnostic interview such as the SCID-5-PD or the IPDE.

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

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

Early identification of BPD through standardized screening is associated with better treatment outcomes. Structured assessment improves diagnostic accuracy compared to unstructured clinical interview alone, reducing both underdiagnosis and misdiagnosis.

Validated BPD Screening Tools

Several brief self-report instruments 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.

McLean Screening Instrument for BPD (MSI-BPD)

The MSI-BPD is one of the most widely used BPD screening tools in both research and clinical settings. Each item corresponds to one of the nine DSM-5-TR criteria. In the original validation study (Zanarini et al., 2003), a cutoff of ≥7 out of 10 yielded sensitivity of 81% and specificity of 85% in a psychiatric treatment-seeking sample. For younger adults (≤25 years), diagnostic efficiency was even higher. Screening tools identify individuals who need further evaluation, not a definitive diagnosis — always follow positive screens with a full diagnostic interview.

A 2020 adolescent validation study (Mirkovic et al., 2020) found that the original cutoff of ≥7 maintained high specificity (0.95) but reduced sensitivity (0.63) in younger populations. An adjusted cutoff of ≥5 improved sensitivity (0.87) while maintaining specificity (0.85) in that sample.

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 & Adolescents)

The Borderline Personality Features Scale for Children (BPFS-C) was developed by Crick and colleagues (2005) as a self-report instrument for identifying borderline personality features in school-age children. It was validated in a normative sample and demonstrated construct validity with evidence that scores were uniquely related to indicators of borderline pathology beyond depressive symptoms. 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.

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) has been shown to improve sensitivity in adolescent clinical samples (Mirkovic et al., 2020).

BPD & 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.
