EUPD Test: Emotionally Unstable Personality Disorder
Emotionally unstable personality disorder (EUPD) is the ICD-10 name for what DSM-5-TR calls borderline personality disorder (BPD). They describe the same pattern, so a BPD screening test covers EUPD as well. In the UK, a diagnosis is made by a mental health professional, usually after a referral from your GP.
EUPD and BPD: why there are two names
The World Health Organization's ICD-10 used the term emotionally unstable personality disorder, with an impulsive type and a borderline type. The American DSM uses borderline personality disorder. Many NHS services have used EUPD in records and letters.
The newer ICD-11 no longer lists separate personality disorder types. It describes personality disorder by severity and allows a "borderline pattern" to be noted. You may therefore see different wording depending on the service and the date.
Taking the test
The 10-question test on this site uses the MSI-BPD, a published screening questionnaire, and takes about two minutes. The in-depth test asks how often you have 27 experiences across nine symptom areas and produces a summary you can print. Neither needs an account or email, and your answers stay in your browser.
Asking for an assessment in the UK
- Book a GP appointment and say you want to talk about your mental health. You can ask for a double appointment.
- Describe the two or three experiences that affect you most and how long they have been happening. A printed summary helps.
- Ask whether a referral to the community mental health team is appropriate and what support is available while you wait.
- If you are in crisis, call NHS 111 and select the mental health option, or call 999 in an emergency. Samaritans are available on 116 123.
Check your own experiences
Both tests are free and private. Your answers stay in your browser, and the result is a starting point for a conversation, not a diagnosis.
Common questions
- Is EUPD the same as BPD?
- Yes, in practice. EUPD is the ICD-10 term and BPD is the DSM term for the same pattern of difficulties. Some people and services prefer one name over the other.
- Can I get an EUPD diagnosis from an online test?
- No. Only a qualified professional can diagnose borderline personality disorder, after considering how long experiences have been present, how widely they affect your life and what else could explain them. The tests here help you describe your experiences and prepare for that conversation.
- What treatment is recommended in the UK?
- NICE guidance recommends structured psychological therapy, such as dialectical behaviour therapy or mentalisation-based therapy, and advises against using medication specifically to treat the personality disorder itself.
