The PC-PTSD-5 is a gated five-symptom screen for deciding whether fuller assessment may help. The PCL-5 rates all 20 DSM-5 PTSD symptoms and reports a broader past-month profile. Neither diagnoses PTSD. Choose by purpose, and never convert a score from one into the other.

How the PC-PTSD-5 works
The PC-PTSD-5 starts with an unscored question about lifetime trauma exposure. If the answer is no, the screen stops. If the answer is yes, five past-month symptom questions follow.
The design is simple.
Each yes symptom answer adds one point. A score of 0 can therefore mean either:
- no qualifying exposure was reported, or
- exposure was reported and no symptom item was marked yes
The number alone does not preserve that distinction. It also does not show symptom intensity because every scored answer is yes or no.
The gate matters.
It is deliberately brief.
The VA PC-PTSD-5 reference documents this branch and the 0-to-5 symptom count.
How the PCL-5 works
The PCL-5 rates 20 past-month symptoms from not at all to extremely. Survey Doctor adds all items for the total and also reports four cluster sums: intrusion, avoidance, negative changes in thoughts and mood, and arousal or reactivity.
The official Standard form includes a field for the worst traumatic event. Survey Doctor does not collect or store that field. Choose one event to keep in mind, or complete the form with a professional if the event focus is unclear.
The field matters.
Survey Doctor does not run the provisional DSM symptom-count rule. Its PCL-5 result contains numeric total and cluster outputs, not a provisional diagnosis.
That is the actual output.
The VA PCL-5 reference describes the 0-to-80 total, four clusters, and a separate provisional diagnostic method. Survey Doctor calculates the scores but does not run that method.
Cutoffs need context
There is no universal PC-PTSD-5 cutoff for every population and purpose. The current VA guidance discusses 4 for a large VA primary-care sample and explains why a lower or higher choice may fit another group or workflow. A lower threshold may find more possible cases and also create more incorrect positive screens.
Tradeoffs remain.
VA PCL-5 guidance discusses a provisional cut-point range of 31 to 33. The VA scoring guide says empirical severity ranges are not available. That range should not be expanded into official mild, moderate, probable, or severe bands.
A cutoff is a policy choice for a defined setting. It should reflect the population, purpose, follow-up capacity, and cost of missed or incorrect screens. It should never become an automatic diagnosis or treatment order.
Document the choice.
Choosing between the tools
Use the PC-PTSD-5 when the first question is whether a fuller PTSD assessment may be useful. Its short format fits an initial screen, but a low result does not rule out PTSD when concern remains.
Use the PCL-5 when you need ratings across all 20 symptoms or want to compare past-month symptom totals over time. It gives more detail, but it still does not verify trauma exposure, daily impact, or other causes.
You do not have to take both. A clinician may begin with the PCL-5 when trauma-related symptoms are already the focus. In another setting, a locally chosen PC-PTSD-5 threshold may lead to a fuller assessment.
Sequence follows purpose.
A safe two-stage workflow
A careful workflow does not depend on one universal number:
- Decide why screening is being done and which population is in scope.
- Choose and document a PC-PTSD-5 threshold supported for that setting.
- Follow up a positive screen with a broader assessment or clinical interview.
- Follow up any serious concern even when the short screen is below threshold.
- Treat the PCL-5 total and clusters as reported symptom data, not a diagnosis.
For an implementation-focused version, read the PTSD screening workflow.
For result interpretation, use the separate PCL-5 score guide or PC-PTSD-5 score guide.
Survey Doctor entry limits
Score-only manual entry is disabled for the PC-PTSD-5 because one number cannot preserve its trauma gate. A zero without that branch could mean two different paths.
PCL-5 manual entry requires all four whole-number cluster sums. Survey Doctor derives the total from them. This preserves the numeric cluster profile but not the 20 item answers, the worst-event field, or evidence for the provisional DSM symptom rule.
What neither tool can decide
Neither questionnaire can determine whether an event meets diagnostic requirements. Neither assesses every cause of overlapping symptoms. Neither can decide which treatment is suitable.
A full evaluation considers timing, daily functioning, other health conditions, substance use, medication effects, and the person's broader history. The score supports that work but does not replace it.
No questionnaire can.
Using results over time
The PC-PTSD-5 is a brief yes-or-no screen, so it is not a detailed severity tracker. The PCL-5 can be repeated to describe symptom trends when the same form, event focus, and timeframe are used.
Do not apply old fixed change rules to declare reliable improvement, treatment response, or remission. Review changes with the clinician who understands the purpose and context.
Tracking is not treatment. A lower result is not a reason to stop existing care.
Keep care decisions separate.
For people taking a screen
Choose the PC-PTSD-5 if you want a brief first check. Choose the PCL-5 if you want a fuller record of past-month symptoms.
Talk with a professional if trauma-related symptoms affect sleep, work, relationships, daily activities, or safety. You do not need to cross a cutoff to ask for help.
If the questions bring up immediate safety concerns, seek support now.
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.
The bottom line
The PC-PTSD-5 is brief and gated by trauma exposure. The PCL-5 is longer and reports a total plus four cluster sums.
Both can support screening. Neither provides a diagnosis, a universal action threshold, or a treatment plan.
They provide information.
