BPD is assessed as a persistent pattern across situations—not one feeling, one event, or one online score. Recognizing some experiences in yourself does not establish a diagnosis.
Direct answer
No. Lists can help you learn the language used to describe experiences, but diagnosis requires a qualified mental health professional to consider the overall pattern, how long it has lasted, where it occurs, its effect on daily life and safety, co-occurring needs, and other possible explanations. NICE describes structured clinical assessment as part of making a diagnosis.
Read NICE’s structured-assessment standardDiagnostic context
DSM-5-TR is the current text revision of the American Psychiatric Association’s diagnostic manual. Its criteria and accompanying clinical information are designed to support trained professionals using clinical judgment.
It is not a public self-scoring quiz. The 20-prompt tool on this site is a separate educational reflection checklist; it does not reproduce DSM criteria or calculate a DSM diagnosis.

Clinical assessment is not simply a tally of familiar experiences. A professional evaluates whether a pattern is enduring and widespread, causes distress or impairment, fits the person’s history and current context, and may be better explained by another condition, substances, medication, physical health, or a temporary situation.
That is why this page does not provide a “how many apply?” calculator, cutoff, probability, or severity label.
NICE: assessment and care recommendationsThese original plain-language summaries organize areas described by public health and professional sources. They are educational examples, not the DSM text, a diagnostic checklist, or proof that a person has BPD. People can experience different combinations and levels of impact.
NIMH: signs, symptoms, diagnosis, and treatmentAREA 1
Separation, rejection, or uncertainty in an important relationship may trigger urgent efforts to prevent the person from leaving or to restore contact.
This can include repeated reassurance seeking or reacting strongly to a change in plans. One reaction by itself does not establish BPD.
AREA 2
Close relationships may shift rapidly between feeling unusually secure and feeling deeply disappointing, unsafe, or conflict-filled.
This can include abrupt changes in trust or closeness. Relationship difficulty has many possible causes and needs context.
AREA 3
A person’s view of who they are, what they value, or where they are going may change sharply or feel difficult to hold onto.
This can include sudden changes in goals, values, or self-evaluation. Ordinary exploration or change is not proof of a disorder.
AREA 4
Strong emotion may be followed by actions that bring meaningful risk or later regret.
Examples can involve spending, substances, driving, eating, or sexual behavior. A clinician also considers mood episodes and other explanations.
AREA 5
Self-harm, suicidal thoughts, threats, preparations, or attempts require a direct safety conversation rather than interpretation through a total score.
If this is current or you may be unable to stay safe, use the crisis guidance below now. Do not wait for an online result.

Sadness, anxiety, irritability, or other emotions may become intense quickly and take time to settle.
Clinicians ask about timing, triggers, duration, sleep, energy, and impact because emotional shifts occur in many conditions and situations.
AREA 7
A person may repeatedly feel internally empty, disconnected, numb, or without a stable sense of meaning.
Emptiness can also occur with depression, trauma, isolation, grief, and other experiences, so it is not specific to BPD.
AREA 8
Anger may feel unusually strong, arrive quickly, or be difficult to express without harming relationships or safety.
A professional explores what happens before, during, and after anger rather than using the presence of anger as a diagnosis.
AREA 9
Under high stress, a person may briefly feel unusually suspicious, unreal, detached from themselves, or disconnected from their surroundings.
These experiences deserve careful assessment because trauma, substances, sleep loss, medical issues, and other conditions can also contribute.
The same outward experience can have different causes and meanings. These questions show why context matters; they are not a differential-diagnosis tool.
| Question | What a professional may explore |
|---|---|
| Did it happen once or repeatedly? | A repeated pattern carries different information from one reaction during an unusually difficult event. |
| Does it occur across settings? | A professional asks whether the experience appears across relationships and situations or only in one specific context. |
| How long has it been present? | Duration and developmental history help distinguish an enduring pattern from a recent or time-limited change. |
| What effect does it have? | Distress, safety, relationships, work, study, health, finances, and daily functioning all matter. |
| Could something else contribute? | Trauma, mood, anxiety, sleep, substance use, medication, physical health, and other conditions may overlap. |
Use the option that matches what you need now. An online reflection summary can organize observations, but it should not be used as proof of a diagnosis.

If you may act on thoughts of harming yourself or someone else, or may be unable to stay safe, contact local emergency services now. In the U.S. or Canada, call or text 988.
