The PCL-5 has 20 questions, each scored from 0 to 4, so the total runs from 0 to 80. The same answers also give four cluster scores, one for each group of PTSD symptoms. A higher total means you reported being more bothered by those symptoms in the past month. The VA's National Center for PTSD says a total of 31 to 33 or higher suggests probable PTSD. That is a reason for a full assessment, not a diagnosis.
How to score the PCL-5
Each question asks how much a problem bothered you in the past month. The five answers run from "Not at all" (0) to "Extremely" (4). In between are "A little bit" (1), "Moderately" (2) and "Quite a bit" (3).
- Add up all 20 answers to get the total, from 0 to 80. No questions are reverse scored or weighted.
- Add up the questions in each cluster to get four cluster scores, using the table below.
- Compare the total with the 31 to 33 range explained further down.
- To apply the DSM-5 symptom rule, count the answers of 2 or higher in each cluster.
| Cluster | Questions | Score range | What the questions cover |
|---|---|---|---|
| Intrusion (B) | 1 to 5 | 0 to 20 | Unwanted memories, nightmares, flashbacks, and strong reactions to reminders |
| Avoidance (C) | 6 and 7 | 0 to 8 | Avoiding thoughts, feelings and outside reminders of the event |
| Negative changes in thoughts and mood (D) | 8 to 14 | 0 to 28 | Memory gaps about the event, harsh beliefs, blame, strong negative feelings, loss of interest, feeling cut off |
| Arousal and reactivity (E) | 15 to 20 | 0 to 24 | Anger, risk taking, feeling on guard, being easily startled, trouble concentrating, trouble sleeping |
The letters B to E are the labels that DSM-5, the manual used to diagnose PTSD, gives each symptom group. The clusters have different numbers of questions, so their raw scores cannot be compared directly. An avoidance score of 4 and an arousal score of 12 both sit halfway up their range.
You can take the PCL-5 on Survey Doctor without an account. It adds up the total and the cluster scores for you. The official form asks you to name the worst event you have been through before you answer. Survey Doctor does not ask for or store that event, so keep one event in mind as you answer. If more than one event is involved, or choosing one is hard, taking the questionnaire with a professional can help.
The DSM-5 symptom rule
The National Center for PTSD also describes a second way to read the answers, which it calls a provisional diagnosis. Each question answered 2 ("Moderately") or higher counts as a symptom that is present. The answers then need to show at least:
- 1 intrusion symptom (questions 1 to 5)
- 1 avoidance symptom (questions 6 and 7)
- 2 symptoms of negative changes in thoughts and mood (questions 8 to 14)
- 2 arousal and reactivity symptoms (questions 15 to 20)
This follows the DSM-5 symptom pattern for PTSD. The VA's scoring guide says the cutoff score tends to give more reliable results than this rule. Anyone who meets either method still needs a further assessment, such as a structured interview, to confirm PTSD.
Survey Doctor shows the total and the four cluster scores, but it does not apply this rule. Your result therefore does not say whether your answers fit the pattern. A doctor or therapist can apply it from your answers to each question. If a score was entered as cluster sums only, the record does not hold the answers the rule needs.
What the 31 to 33 cutoff means
The National Center for PTSD says early research points to a cutoff between 31 and 33 for probable PTSD. It gives a range because the best cut point depends on who is being screened and why. A lower cut point flags more people who may have PTSD, but also more people who do not. A higher cut point gives fewer false alarms but misses more people.
A total of 31 to 33 or higher is a good reason to book a full assessment. It does not confirm PTSD, and a total below 31 does not rule it out. Symptoms that affect your daily life are worth raising with a professional at any score. Clinics choosing a cut point can follow the PTSD screening workflow.
There are no official severity bands
The VA's scoring guide says there are currently no research-based severity ranges for the PCL-5. Charts that split 0 to 80 into mild, moderate and severe are not part of the official scoring. Survey Doctor does not put a severity label on your total for this reason. If an older Survey Doctor record shows a label, it is not an official PCL-5 grade.
How much change is meaningful
The VA notes that there is limited evidence on how much change counts. Its guidance suggests a 10-point drop as a sign that someone is responding to treatment. That figure draws on data from both the PCL-5 and the older PCL. The VA also cites one study of male veterans (Marx et al., 2022). In that study, a total below 28 could serve as a sign of clinically significant change. The VA describes this as the point where the person is likely to belong to a healthy population. The VA gives no separate figure for reliable change, meaning a change too large to be explained by measurement error.
These figures help track care, but they do not prove recovery. A lower total is also not a reason to stop care you are getting. Compare scores only when the same form and the same past-month timeframe were used. Keep the same event in mind each time if you can. The PCL-5 weekly form covers a different period, and the older PCL-C uses a different scale. Scores from either cannot be compared directly with this one. The guide to tracking recovery from trauma explains how to read a series of scores.
What a score cannot tell you
The PCL-5 measures how much 20 symptoms bothered you in the past month. A high score is a good reason to book an appointment, but it is not a diagnosis. The questionnaire does not check whether the event you had in mind meets the definition of trauma used for diagnosis. It also cannot show how long symptoms have lasted or how much they affect your life. Depression, alcohol or drug use and some medical conditions can cause similar problems, which the questionnaire cannot rule out. A doctor or therapist weighs all of this before making a diagnosis.
If you are still wondering whether what you feel could be PTSD, read do I have PTSD?. If you took the shorter PC-PTSD-5 instead, its score works differently. The PCL-5 and PC-PTSD-5 comparison explains how the two fit together.
When to talk to a professional
If the questions brought up thoughts of suicide or self-harm, or you feel unsafe, get help now. Do not wait to work out what your score means.
If you need help now. In the US, Call 988 or text 988. Call 911 if you are in immediate danger. Outside the US, contact your local emergency number or find support in your country.
Book an appointment with a doctor or therapist if your total is near or above 31 to 33. Do the same at any score if symptoms are affecting your sleep, work, relationships or sense of safety. A primary care doctor is a good first step. You can also look for a licensed therapist who works with trauma. You decide how much to share about what happened.
It helps to bring:
- your total and four cluster scores, with the date you took the PCL-5
- your answers to each question, if you have them, so the symptom rule can be checked
- the event you had in mind, if you are comfortable naming it
- how long the problems have lasted and what they get in the way of
- any changes in sleep, mood, drinking or drug use
- earlier PCL-5 results, so changes can be compared
If you start treatment, your doctor or therapist may ask you to take the PCL-5 again during care. Comparing totals on the same form shows whether your reported symptoms are changing.
