It’s normal to feel scared following a traumatic event. Trauma triggers our fight-or-flight response, leaving us with a range of emotions that can affect us in both the short and long term.
Around 7 in 10 people experience at least one trauma in their lives (Knipscheer, 2020). While the stress associated with trauma fades significantly over time for many, others are affected long after it happens, making it difficult to function on a daily basis.
If you continue feeling scared or stressed for weeks or even months after an event, you might wonder if you have post-traumatic stress disorder (PTSD).
Around 7% of people experience PTSD at some point in their lives, with women being more likely to have it (Knipscheer, 2020; Institute of Medicine, 2014). There are online PTSD assessments you can take, but only a mental health professional can make an official diagnosis.

What is PTSD?
PTSD is a mental health condition that can develop after a traumatic event.
Traumas can include a wide range of things including the death of a loved one, war, physical or sexual assault, abuse, a car accident, or surviving a natural disaster. Even if a person didn’t directly experience the trauma themselves, they could still have PTSD from seeing a loved one go through it.
Someone with PTSD grapples with feelings of fear or stress for months following the event––even when they’re no longer in danger.
PTSD: understanding post-traumatic stress disorder
Common symptoms of PTSD
The symptoms of PTSD are often so severe that they interfere with a person’s daily life and overall well-being.
PTSD is typically diagnosed when a person has experienced the following symptoms for at least one month after a traumatic incident:
- Re-experiencing at least one symptom like flashbacks, nightmares, or intrusive thoughts
- Having at least one avoidance symptom, such as staying away from places, events, things, or thoughts that remind them of the traumatic experience (for example, not getting in a car after being in a car accident)
- At least two arousal and reactivity symptoms like difficulty sleeping, angry outbursts, being easily startled, or feeling on edge
- A minimum of two cognition and mood symptoms, such as difficulty remembering trauma, negative thoughts, feelings of blame or guilt, or a loss of interest in previously enjoyable activities
Is there a test for PTSD?
You can find PTSD self-assessments online from the Anxiety & Depression Association of America, but it’s important to remember that a treatable diagnosis requires a full assessment by a mental healthcare professional.
Healthcare providers use one of three diagnostic tests for PTSD. These include the Davidson Trauma Scale (DTS), Post-traumatic Stress Diagnostic Scale (PDS), and PTSD Checklist for DSM-5 (PCL-5).
Davidson Trauma Scale (DTS)
Developed in the late ‘90s, the DTS is a 17-item self-reported questionnaire that asks patients to rate the frequency and severity of their PTSD symptoms.
Frequency scores range from 0 (not at all) to 4 (every day). Severity scores also range from 0 (not at all distressing) to 4 (extremely distressing).
For example, in response to the question “Have you had painful images, memories, or thoughts of the event?” a person would provide two scores: one representing how frequently they experienced the symptom, and the other representing the severity of it.

Post-traumatic Stress Diagnostic Scale (PDS)
The PDS is a 24-item questionnaire assessing the severity of symptoms from the past month using a scale from 0 (not at all) to 4 (severe, six or more times a week).
Twenty questions focus on PTSD symptoms, such as unwanted upsetting memories about the trauma. The remaining questions involve identifying the original trauma and when symptoms first began.
PTSD Checklist for DSM-5 (PCL-5)
This 20-item questionnaire is used to diagnose PTSD and monitoring the effects of treatment.
There are three versions: one for civilians, one for military personnel, and one for specific types of trauma. Each test contains the same questions with slight variations in wording to describe the trauma.
All 20 questions focus on PTSD symptoms; for example, how often you’re bothered by repeated, disturbing, and unwanted memories of a traumatic experience. Patients are asked to rate the severity of each symptom on a five-point scale, with 0 meaning not severe at all, and 5 representing extreme severity.
While not a replacement for an official diagnosis, a PTSD self-test can help you assess whether it’s worth seeking professional help.
Here is a sample online PTSD test you can take. For each question, rate how often you experienced the symptom in the past month on a 1 to 5 scale. Then, total your scores.
- 1 = Not at all
- 2 = Sometimes
- 3 = Moderately
- 4 = Often
- 5 = Extremely often

Treatment options for PTSD
Not everyone develops PTSD after experiencing a traumatic event, but if you do, getting help and support from loved ones and a healthcare professional is key to recovery.
Often, a combination of medication and psychotherapy is recommended (Institute of Medicine, 2014). If you feel that your symptoms are interfering with your ability to function, contact a mental health professional.
Call the Substance Abuse and Mental Health Services Administration (SAMHSA) at 1-800-662-HELP for 24/7 confidential support and referral for PTSD treatment near you.
