Do you experience intense fear of being abandoned, even when there’s no real threat? Do your relationships swing between feeling perfect and feeling unbearable — sometimes within the same day? Do you struggle to hold onto a stable sense of who you are?
These are hallmark experiences of Borderline Personality Disorder (BPD) — a condition that affects approximately 1.6% of the adult population and is one of the most misunderstood diagnoses in mental health.
This free BPD test is designed to help you explore whether your emotional patterns and relationship experiences align with the recognized criteria for BPD. It is not a diagnostic tool — only a licensed mental health professional can diagnose BPD — but it can help you understand your experiences and decide whether to seek a professional evaluation.
Your responses are completely private and anonymous. Results are instant.
What Is Borderline Personality Disorder (BPD)?
Borderline Personality Disorder is a Cluster B personality disorder characterized by intense emotional instability, unstable self-image, volatile relationships, and impulsive behavior. People with BPD often experience emotions more intensely than others and have difficulty returning to an emotional baseline once triggered.
BPD is not a character flaw or a sign of weakness. It is a recognized mental health condition listed in the DSM-5, and it is highly treatable — particularly with Dialectical Behavior Therapy (DBT), developed by Dr. Marsha Linehan specifically to address the emotional dysregulation at the core of BPD.
The 9 DSM-5 Criteria for BPD
According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), a BPD diagnosis requires that a person show a pervasive pattern of instability across at least 5 of the following 9 areas, beginning in early adulthood:
1. Fear of abandonment
Frantic efforts to avoid real or imagined abandonment — whether the threat is real or perceived. This can manifest as clinging behavior, sudden anger, or panic when someone is simply late to respond to a message.
2. Unstable relationships
A pattern of intense, unstable relationships characterized by alternating between idealization (“this person is perfect”) and devaluation (“they are completely awful”). This is sometimes called “splitting.”
3. Identity disturbance
A persistently unstable or fragmented self-image. People with BPD often describe not knowing who they really are — their values, goals, and sense of self shift depending on who they are with.
4. Impulsivity
Impulsive behavior in at least two self-damaging areas, such as spending, sex, substance use, reckless driving, or binge eating.
5. Suicidal behavior or self-harm
Recurrent suicidal gestures, threats, or self-harming behavior. This criterion is one reason BPD requires careful, professional evaluation — if you are experiencing thoughts of self-harm, please reach out to a crisis service.
6. Emotional instability
Intense but short-lived mood episodes — pronounced anxiety, irritability, or dysphoria — typically lasting a few hours, rarely more than a few days.
7. Chronic emptiness
A persistent sense of inner emptiness or emotional numbness that many with BPD describe as feeling like “nothing inside.”
8. Intense or uncontrollable anger
Difficulty controlling anger — frequent outbursts, constant irritability, or physical fights — often followed by shame or guilt.
9. Stress-related paranoia or dissociation
Transient, stress-triggered paranoid thoughts or dissociative symptoms, such as feeling detached from your body or surroundings.
How This BPD Test Works
This assessment covers the core emotional, relational, and behavioral patterns associated with BPD. For each statement, select the response that most accurately describes your typical experience — not how you feel on your worst day, but your general pattern over the past several months.
Scoring: Your answers generate a total score used to place you in one of three ranges:
- Low BPD traits — Few or no traits aligned with BPD criteria
- Moderate BPD traits — Some patterns that may warrant professional exploration
- High BPD traits — Significant alignment with BPD criteria; professional evaluation is strongly recommended
This test is for informational purposes only. It is not a clinical diagnosis.
Understanding Your Results
If your score is low: This suggests your emotional patterns are not closely aligned with BPD criteria. However, if you are experiencing distress in your relationships or emotional life, that is still worth exploring with a mental health professional — with or without a BPD diagnosis.
If your score is moderate: You may share some emotional patterns common in BPD, or these traits may reflect another condition such as anxiety, PTSD, or ADHD. A professional evaluation can help clarify what is driving your experiences.
If your score is high: Your responses suggest significant alignment with BPD traits. This does not mean you have BPD — diagnosis requires a full clinical evaluation — but it does suggest that speaking with a mental health professional would be worthwhile. BPD is highly treatable. Many people with BPD see significant improvement with the right support.
The 4 Types of BPD
While BPD is a single diagnosis, researchers have identified four informal subtypes that describe different ways the disorder can present. Understanding these can help explain why BPD looks so different from person to person.
Quiet BPD (Discouraged BPD)
Sometimes called “high-functioning BPD,” Quiet BPD involves directing intense emotions inward rather than outward. People with Quiet BPD may appear calm and composed on the surface while experiencing extreme internal turmoil. Self-blame, withdrawal, and self-harm are more common than outward anger or explosive behavior.
Impulsive BPD
Characterized by thrill-seeking, risk-taking, and charismatic energy. People with this subtype are often outgoing and engaging but prone to reckless decisions — substance use, unsafe sex, impulsive spending — driven by a need for stimulation and an inability to tolerate boredom.
Petulant BPD
Unpredictable, irritable, and prone to sudden emotional outbursts. People with Petulant BPD often feel deeply resentful and struggle with frustration tolerance. Their mood swings are intense and visible to those around them.
Self-destructive BPD
Marked by self-loathing, reckless behavior directed at oneself, and a higher risk of self-harm. People with this subtype are often highly critical of themselves and may engage in behaviors that are consciously or unconsciously self-punishing.
These subtypes are not official DSM-5 classifications — they are descriptive frameworks clinicians use to understand the diversity of BPD presentations.
BPD vs Bipolar Disorder — Key Differences
BPD and Bipolar Disorder are frequently confused because both involve intense mood instability. However, they are distinct conditions with different causes, patterns, and treatments.
| BPD | Bipolar Disorder | |
|---|---|---|
| Mood episode duration | Hours to days | Days to weeks or months |
| Trigger | Usually interpersonal | Often without external trigger |
| Identity issues | Central feature | Not a core feature |
| Impulsivity | Chronic pattern | Mainly during manic episodes |
| Fear of abandonment | Core symptom | Not a core symptom |
| Best treatment | DBT, schema therapy | Mood stabilizers, CBT |
Both conditions can co-occur. If you are uncertain which may apply to you, a psychiatric evaluation — not an online test — is the appropriate next step. If you want to explore further, take our Bipolar Test to compare your responses across both assessments.
BPD and Co-occurring Conditions
BPD rarely appears alone. The most common conditions that co-occur with BPD:
- Depression — Chronic low mood and emptiness overlap significantly with BPD’s emotional instability
- PTSD — Many people with BPD have a history of trauma; some researchers argue BPD is a complex trauma response. See our PTSD Test.
- Anxiety disorders — Particularly social anxiety and generalized anxiety
- ADHD — Impulsivity and emotional dysregulation are shared features. See our ADD/ADHD Test.
- Eating disorders — Impulsivity and distorted self-image connect both conditions. See our Eating Disorder Test.
These overlaps make BPD one of the most complex conditions to diagnose, which is why professional evaluation is essential.
Treatment for BPD — There Is Reason for Hope
BPD has historically been considered difficult to treat, but that view has shifted significantly. Research now shows that with the right therapy, the majority of people with BPD experience substantial symptom reduction.
Dialectical Behavior Therapy (DBT)
Developed by Dr. Marsha Linehan — who has been open about her own BPD diagnosis — DBT is the gold standard treatment for BPD. It combines cognitive-behavioral techniques with acceptance and mindfulness practices, and focuses specifically on the emotional dysregulation at the core of BPD.
Schema Therapy
Addresses deeply rooted patterns of thinking and relating that originate in early childhood experiences. Particularly effective for the identity disturbance and unstable relationship patterns in BPD.
Mentalization-Based Therapy (MBT)
Developed by Peter Fonagy, MBT focuses on improving a person’s ability to understand their own and others’ mental states — a skill often impaired in BPD.
If you scored highly on this assessment, speaking with a therapist experienced in BPD is a meaningful next step. DBT is available in both individual and group formats, and many practitioners now offer it via telehealth.
Frequently Asked Questions About BPD
What is the difference between BPD and bipolar disorder?
BPD and bipolar disorder both involve mood instability, but they differ in important ways. BPD mood shifts are typically triggered by interpersonal events and last hours to days, whereas bipolar mood episodes occur more independently and last days to weeks or months. BPD also involves identity disturbance and fear of abandonment that are not core features of bipolar disorder. Both conditions can co-exist in the same person.
Can you have BPD and not know it?
Yes — many people with BPD go undiagnosed for years, particularly those with Quiet BPD whose symptoms are directed inward rather than expressed outwardly. BPD is also frequently misdiagnosed as bipolar disorder, depression, or anxiety before the correct diagnosis is reached.
Is BPD more common in women?
Historically, BPD has been diagnosed more often in women, but recent research suggests this reflects diagnostic bias rather than a true gender difference. Men with BPD are more likely to be misdiagnosed with antisocial personality disorder or substance use disorders.
What does “splitting” mean in BPD?
Splitting — also called black-and-white thinking — is the tendency to view people and situations as either completely good or completely bad, with little middle ground. In BPD, splitting applies especially to relationships: a person can idealize someone (“my favorite person”) and then suddenly devalue them when they are perceived as letting them down.
Can BPD be treated, or does it go away?
BPD is highly treatable. Long-term studies show that many people with BPD experience significant symptom reduction over time, particularly with therapy. The Collaborative Longitudinal Personality Disorders Study found that 85% of BPD patients achieved remission within 10 years. DBT, schema therapy, and MBT have the strongest evidence base.
What is Quiet BPD?
Quiet BPD — also called high-functioning BPD — is an informal subtype in which symptoms are expressed inwardly rather than outwardly. People with Quiet BPD direct their emotional storms at themselves rather than others, often appearing stable to the outside world while experiencing intense internal suffering. Self-blame, self-isolation, and self-harm are more common than explosive anger.
How is BPD diagnosed?
BPD is diagnosed by a licensed mental health professional — a psychiatrist, psychologist, or clinical social worker — through a structured clinical interview. Tools like the McLean Screening Instrument for BPD (MSI-BPD) and the Structured Clinical Interview for DSM-5 Personality Disorders (SCID-5-PD) are commonly used. Online tests like this one can point you toward a professional evaluation but cannot replace it.
