Before you begin

This test is the PC-PTSD-5, a short screening tool developed by the US National Center for PTSD and made available for public use. It begins with a question about whether you have been exposed to a traumatic event, then 5 yes-or-no questions about the past month, and a score from 0 to 5 appears. Your answers are not saved, and the result is a screening tool, not a diagnosis.

  • You do not need to describe the details of the event; it is enough to answer yes or no.
  • Your answers are not sent or stored anywhere.
  • If you have thoughts of harming yourself, contact 16328 or 123 immediately.

After an accident, an assault, or a sudden loss, most people need time for the impact to settle. But when nightmares, constant alertness, and avoidance continue for weeks, it may be post-traumatic stress disorder. These short questions help you check.

Start the PTSD test

Sometimes people go through events that are frightening, horrible, or exceptionally traumatic. Answer yes or no.

1Examples of such events include a serious accident or fire; an assault or physical or sexual abuse; an earthquake or flood; war; seeing someone being killed or seriously injured; or the death of a loved one by murder or suicide. Have you ever experienced an event of this kind?
2In the past month, have you had nightmares about the event(s), or thought about it when you did not want to?
3In the past month, have you tried hard not to think about the event, or gone out of your way to avoid situations that remind you of it?
4In the past month, have you been constantly on guard, extremely watchful, or easily startled?
5In the past month, have you felt numb or detached from other people, from your activities, or from your surroundings?
6In the past month, have you felt guilty, or been unable to stop blaming yourself or others for the event or for any problems it may have caused?

How is the score calculated?

The first question, about exposure to a traumatic event, is not part of the score; it determines whether the scale applies to you. If your answer is “yes,” each “yes” in the five following questions equals one point, so the result is from 0 to 5. The scale's developers set a score of 3 as the cutoff:

0 – 2Negative screenMonitor your symptoms and ask for help if they continue
3 – 5Positive screenAssessment with a psychiatrist to confirm the diagnosis

What to do after your result

0–2: Give yourself time

Reactions after trauma are common and usually settle within weeks. Keep your routine, talk with people you trust, and retake the test if you do not improve.

3–5: Ask for an assessment

Persistent symptoms respond to trauma-focused psychotherapy, and an assessment determines the plan that suits you. Read about PTSD treatment.

What is the PC-PTSD-5?

The researcher Annabel Prins and her colleagues at the National Center for PTSD, part of the US Department of Veterans Affairs, developed this scale, and it was published in 2016 to match the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders. Its five questions correspond to the core symptom clusters: re-experiencing, avoidance, hyperarousal, emotional numbing, and blaming oneself or others.

In the original validation study, a score of 3 or higher picked up the great majority of PTSD cases confirmed by a clinical interview, and a later study in 2021 confirmed its accuracy and ease of use in primary care clinics. The scale is available for public use without prior permission.

Symptoms worth noticing after trauma

  • Reliving the event in intrusive memories or nightmares, or feeling as if it is happening all over again.
  • Avoiding places, people, or conversations that remind you of it.
  • Constant tension, trouble sleeping and concentrating, and being startled by the slightest sounds.
  • Persistent negative feelings such as guilt, fear, and anger, and a dulling of interest in what used to bring you joy.

If these symptoms last more than a month and affect your life, they deserve an assessment. You will find a fuller explanation in the article on PTSD symptoms.

How do you support someone who has been through trauma?

If the test is for a relative of yours, how you treat them may ease a great deal for them:

  • Listen without pressing them to tell the details, and let them choose when to speak and how much.
  • Avoid phrases like “forget what happened” or “it could have been worse.”
  • Help them keep their routine of sleeping, eating, and going out as much as possible.
  • Watch for signs of severe withdrawal, increased substance use, or talk of death, and encourage them to get assessed.

Remember that family support does not replace treatment when symptoms persist, but it makes the road to treatment easier.

Limits of the test

  • It does not diagnose PTSD; a diagnosis requires an interview with a psychiatrist.
  • It was designed for adults in primary care and is not suitable for assessing children.
  • It does not measure symptom severity; it screens for who needs a deeper assessment.
  • If the trauma is very recent, the symptoms may be an acute reaction that settles with time.
  • Depression, anxiety, and substance use can overlap with the result, and a low score does not cancel out real suffering.

Trauma and addiction

Psychological trauma is among the strongest drivers of substance use; alcohol, sedatives, and opioid painkillers may dull memories and bring temporary sleep, but they disrupt the natural recovery from trauma and add a dependence that is hard to leave. If you find yourself turning to a substance to forget, treating both together works better, as the article on PTSD and addiction explains.

What is the difference between psychological trauma and post-traumatic stress disorder?

Trauma is the event and the natural reactions that follow it; the disorder is when symptoms continue for more than a month and disrupt your life.

Is the PC-PTSD-5 test accurate?

It is a well-studied screening tool, and a score of 3 or higher picks up most cases, but it screens for who needs an assessment and does not diagnose.

Why does the test first ask me about a traumatic event?

Because PTSD is linked to exposure to a traumatic event; if you have not experienced an event of this kind, the scale does not apply to you.

When do PTSD symptoms appear?

Usually within the first months after the event, though they can sometimes be delayed for months or years.

Can PTSD be treated?

Yes, trauma-focused psychotherapy helps many people with the disorder, and the doctor may add medication depending on the case.

Does this disorder affect children?

Yes, but its symptoms differ in them, and they need a specialist assessment in which the parents take part.

Are my answers saved?

No, the calculation is done on your device only, and the answers are not sent to any party.
