PCL-5
Adult PTSD Screener

1. What the PCL-5 is (and what it isn’t)
The PCL-5 (PTSD Checklist for DSM-5) is a short, evidence-based trauma screener that helps estimate how much PTSD-related symptoms have been affecting you over the past month. It asks about 20 common trauma-response symptoms, such as intrusive memories, avoidance, negative shifts in mood or beliefs, hypervigilance, startle, sleep difficulty, and concentration problems.
​
It is widely used because it is practical, structured, and helpful for both screening and tracking change over time. That said, it is not a diagnosis. A high score can suggest that PTSD symptoms may be clinically important and worth discussing with a qualified professional, but it cannot confirm PTSD by itself or fully explain the context behind what you are experiencing.
Instead, think of the PCL-5 as a grounded starting point: a way to notice patterns, put words to trauma-related distress, and decide whether follow-up evaluation or support would be helpful.
2. Who is the PCL-5 for?
The PCL-5 is for people who want to check in on trauma-related symptoms after a very stressful experience, especially if they:
​
-
keep getting unwanted memories, dreams, or body-based reactions tied to what happened
-
avoid reminders, conversations, places, or feelings connected to the event
-
feel more on edge, watchful, irritable, startled, or emotionally shut down than usual
-
want to track symptoms over time during therapy, after a stressful period, or while noticing whether things are improving or worsening
If you are neurodivergent, the PCL-5 can still be useful - but context matters. Trauma symptoms can overlap with burnout, sensory overload, chronic overwhelm, panic, OCD, shutdown, masking fatigue, sleep disruption, and executive function strain. A score can be informative, but it is never the whole story. The goal is not just to label symptoms, but to understand what pattern best fits your lived experience.
3. What to expect when taking the PCL-5
Most people finish the PCL-5 in about 5–10 minutes.
You will answer 20 questions while keeping your worst event (or the stressful experience you are screening in relation to) in mind. For each symptom, you will choose how much it bothered you in the past month:
-
Not at all
-
A little bit
-
Moderately
-
Quite a bit
-
Extremely
Each item is rated from 0 to 4. The questions cover four major PTSD symptom areas:
-
intrusion / re-experiencing
-
avoidance
-
changes in thoughts and mood
-
alertness / reactivity
Unlike some screeners, the PCL-5 does not measure every part of trauma history by itself. It works best as one part of a fuller clinical picture.
4. Understanding your score
Each item is scored from 0 to 4, for a total score between 0 and 80.
There are two common ways to interpret the PCL-5:
1. Total score method
A higher total score generally means more trauma-related symptom burden. A score in the 31–33 range or above is often used as a signal that PTSD may be worth evaluating more closely, though the most appropriate cutoff can vary depending on the setting and the purpose of screening.
​
2. Symptom-pattern method
A provisional PTSD pattern can also be identified by looking at whether symptoms rated 2 (Moderately) or higher match the DSM-5 symptom rule:
-
at least 1 intrusion symptom
-
at least 1 avoidance symptom
-
at least 2 thoughts/mood symptoms
-
at least 2 alertness/reactivity symptoms
Important note: the PCL-5 can flag a possible PTSD pattern, but it does not diagnose PTSD. Interpretation should happen in context, ideally with a clinician who can look at trauma history, timing, functional impact, overlap with other conditions, and what support would be most useful.
Also, trauma screeners can bring up strong feelings. If taking this screener leaves you distressed, overwhelmed, or feeling unsafe, pause and reach out for support.
5. Next steps
If your score is below the commonly used screening range
You might consider:
-
noticing whether specific symptoms still feel disruptive, even if the total score is lower
-
tracking your score over time to watch for patterns, especially during stressful seasons, trauma reminders, or burnout
-
paying attention to the areas that feel most affected, such as sleep, hypervigilance, avoidance, or emotional numbing
If your score falls in or above the commonly used screening range
It may be time to add structured support:
-
talk with a trauma-informed therapist, psychologist, or medical provider
-
consider a fuller trauma assessment rather than relying on the screener alone
-
ask about what else may be interacting with the symptoms, such as panic, OCD, depression, insomnia, ADHD/autistic overwhelm, chronic stress, or burnout, so your plan fits the full picture
If your score is high, your symptoms are disrupting daily life, or the pattern stays elevated over time
Strongly consider:
-
scheduling an appointment with a qualified mental health professional soon
-
discussing evidence-based PTSD treatment options, such as trauma-focused therapy, and whether added medical support may help with sleep, anxiety, or related symptoms when appropriate
-
leaning on support now - trusted people, reduced demands where possible, grounding skills, and a clear plan for what to do if you become overwhelmed
If you feel unsafe, at risk of harming yourself, or unable to stay grounded, seek immediate help through 911 or your local emergency number. In the U.S. and Canada, you can also call or text 988 for crisis support.
