Borderline personality disorder

Intense emotions and difficulties with your sense of self or relationships can feel exhausting. You deserve to be heard carefully and to understand the care available to you.

Understand the term Care & next steps
01 / Get a clearer picture

Understanding the pattern, without reducing you to it.

BPD can involve difficulty regulating intense emotions, an unsettled sense of self and relationship difficulties. Experiences and their impact vary.

BPD and bipolar disorder are different conditions. Assessment considers mood episodes and the wider pattern, rather than using quick mood changes alone to decide between them.

Based on NIMH

BPD is a clinical assessment term, not a judgment of your character or a synonym for bipolar disorder.
A visual explanation

Care addresses more than one part of your life.

  • Your emotions

    What becomes difficult to regulate

  • Your sense of self

    What feels uncertain or painful

  • Your relationships

    Patterns and needs you want understood

  • Your safety & care

A closer look

Care can address everyday life, as well as times of crisis.

BPD can involve intense emotions, difficulties in relationships and changes in self-view. Experiences differ, and no single relationship conflict or emotional reaction establishes the diagnosis.

The term should not be used as a judgment about someone’s character. Ask how care can help with the particular patterns and daily difficulties you want to change.

Based on NIMH · American Psychiatric Association

Your experience and goals stay central when planning care together.
Understanding the words

Reflection, assessment and care have different purposes.

You can ask for an explanation or support without choosing a diagnostic label.

Everyday traits

Words such as reserved, organized or expressive can describe preferences. A personality reflection is not a disorder assessment.

A clinical pattern

A professional considers the pattern, context and impact. A label needs more than one interaction or a short online score.

Your care questions

You can ask how a term was reached, what the plan addresses and how your own goals will be included.

Based on NIMH

02 / Make sense of what has changed

Experiences you may want understood.

Examples can help you describe a concern. They do not form a diagnostic checklist, and not everyone experiences all of them.

Intense emotions

Emotions that become intense and difficult to regulate.

Sense of self

An uncertain sense of self or persistent feelings of emptiness.

Relationships

Relationship difficulties and fears of abandonment.

Responses & safety

Impulsive responses or distress that affects your safety.

Based on NIMH

In everyday life

One possible pattern can be explored without blaming the person.

In this fictional example, an ambiguous message feels like rejection. Strong emotion makes responding difficult, and the person later wants help understanding what happened. A therapist can explore context and options without treating the example as proof of BPD.

Fictional examples to explain an experience. They are not a checklist or a diagnosis.

  1. A situation

    Something happens whose meaning feels uncertain.

  2. An emotional response

    The feeling becomes intense and hard to manage.

  3. A response and its effects

    What happens next may create further distress.

  4. Support and alternatives

    Therapy can help explore the pattern and practice different responses.

A fictional possible pattern; neither universal nor diagnostic.

03 / Put your experience into context

A conversation considers more than a screening score.

A mental-health professional reviews symptoms, history, functioning and possible overlapping conditions. Medical assessment can help consider other causes.

MSI-BPD is a screening research measure; DERS-16 concerns emotion-regulation difficulties across conditions. Neither establishes BPD, and combining them does not create a diagnosis.

Make a few notes
Room for your questions

A careful assessment considers overlapping concerns.

Mood, trauma-related symptoms, substance use and other conditions can overlap with BPD experiences. BPD and bipolar disorder are distinct, and timing alone is not enough for a visitor to tell them apart.

Ask the clinician what the diagnosis explains, which other needs have been considered and how your treatment history and preferences inform the plan.

Based on NIMH · American Psychiatric Association

04 / Explore your support options

Structured psychological care is available.

You and your clinician can discuss what fits your needs, preferences and health.

Based on NIMH · American Psychiatric Association

Professional care

Structured psychotherapy is central to care. DBT is one approach that teaches skills for emotions and relationships; no single therapy is a universal best fit. You can ask how the approach and goals were chosen.

Support in your daily life

Medication is not first-line treatment for BPD itself; a clinician may consider it for particular or coexisting needs. Ask how your care plan addresses safety, day-to-day goals and support between sessions.

Understand your options

Structured psychological treatment has specific aims.

Psychotherapy is the main treatment for BPD. A service should explain its approach, expected participation and how it will address the difficulties you identify. Medicines may have a role for co-occurring conditions or specific targets; they are not a general substitute for BPD-focused psychotherapy.

  • Dialectical behavior therapy

    Works on skills related to intense emotions, harmful responses and relationships.

  • Mentalization-based therapy

    Works on understanding your own and other people’s mental states, especially in relationships.

  • Other structured approaches

    A clinician can explain alternatives, their evidence and fit with your needs.

Treatment purposes, not a ranking or a self-guided course.

Based on NIMH · American Psychiatric Association · NHS

Make room for what helps

Ask for a plan that remains useful between appointments.

Discuss who to contact if difficulties worsen, how ongoing care is coordinated and what support is available while waiting. Urgent safety concerns need direct help rather than a screening result.

Family or trusted supporters may benefit from their own education and support. Agree their role with the care team while keeping your own voice in decisions. Improvement is possible, with a course that varies between people.

Questionnaires you might hear about

These references address different questions. They are not two tests to complete for confirmation.

MSI-BPD

Screening context for possible BPD features

McLean Screening Instrument for Borderline Personality Disorder

The original ten-item study compared the screen with a DSM-IV interview in adults with treatment histories.

What it can and cannot tell you

A selected clinical sample does not establish accuracy for every visitor. Exact current form, digital rights, specialist interpretation and a support pathway remain under review; no public runner is available.

Read the original screening study

Based on Zanarini and colleagues · PubMed

DERS-16

A broader emotion-regulation companion

Difficulties in Emotion Regulation Scale-16

A sixteen-item research measure of difficulties managing emotions, studied in clinical and community samples.

What it can and cannot tell you

It is not a BPD test, suicide-risk assessment or second diagnostic confirmation. Exact implementation and rights need review before public use.

Read the original measure study

Based on Bjureberg and colleagues · Springer

You can seek help without a score. A questionnaire cannot replace a conversation about your needs.

You can start right here

Your first sentence does not need to be perfect.

You can begin with one difficulty, or ask for an explanation of an existing diagnosis. Your questions may include the therapy offered, how to get support during a crisis and how progress will be reviewed.

Based on NIMH

“My emotions and relationships have been difficult to manage. Can we talk about assessment, safety and care options?”

Things you may be wondering

Your questions, with room for nuance.

You can read just the answer you need.

Is BPD the same as bipolar disorder?

No. They are distinct conditions with some overlapping experiences. A clinician considers the wider history and pattern rather than relying on a short comparison or score.

Based on NIMH

Does an MSI-BPD score establish the diagnosis?

No. A screening measure cannot replace a comprehensive assessment or determine the right treatment.

Based on NIMH · American Psychiatric Association

Is DBT the only possible treatment?

No. Several structured psychological approaches may be considered. Ask why a particular approach fits your needs and what evidence supports it.

Based on American Psychiatric Association · NHS

Can symptoms and daily life improve?

Yes, effective care can help. Improvement varies and should be discussed through meaningful goals and ongoing review rather than a fixed promise.
