Primary Care PTSD Screen for DSM-5-TR (PC-PTSD-5)
The PC-PTSD-5 is a brief, highly sensitive screening instrument designed to identify probable PTSD in primary care and general medical settings. Developed by Prins, Bovin, Smolenski, and colleagues (2016), this 5-item tool reflects DSM-5-TR PTSD criteria and focuses on intrusion, avoidance, cognitive/mood changes, and arousal. Its simplicity allows rapid identification of individuals who may benefit from a fuller diagnostic evaluation. A score of 3 or more “Yes” responses is the recommended threshold for a positive screen. The PC-PTSD-5 is widely used in primary care, VA systems, and community health settings due to its accuracy, brevity, and clinical practicality.
- At intake in primary care, mental health, or integrated care settings
- Annually for high-risk populations (e.g., veterans, first responders, survivors of violence)
- Following known traumatic exposure or significant psychosocial events
- As clinically indicated when PTSD symptoms or trauma histories emerge
PC-PTSD-5 Score Interpreter
≥3 Yes responses meets the recommended threshold for probable PTSD. A comprehensive clinical evaluation is indicated.
5 items, each scored Yes=1/No=0. Higher scores indicate more PTSD symptom domains endorsed in the past month.
| Total score (Yes responses) | Interpretation |
|---|---|
| 3+ | Positive screen≥3 Yes responses meets the recommended threshold for probable PTSD. A comprehensive clinical evaluation is indicated. |
| 0–2 | Negative screenFewer than 3 Yes responses. Screen is negative; clinician judgment should guide any further assessment based on the full clinical picture. |

Foundational Context
PTSD is frequently underdetected in primary care despite its strong association with physical health conditions, chronic pain, sleep disturbance, anxiety, and depression. The original PC-PTSD aligned with DSM-IV criteria, and the PC-PTSD-5 was developed to reflect the updated symptom structure and diagnostic requirements of DSM-5-TR.
In a large validation sample of U.S. veterans, Prins et al. (2016) demonstrated that the PC-PTSD-5 has strong sensitivity and specificity, especially when using a cutoff of three symptoms. Its streamlined design makes it ideal for rapid screening before administering a more comprehensive assessment (e.g., PCL-5). The PC-PTSD-5 is specifically optimized for medical settings where time and resources are limited but early identification is essential.
What the Assessment Measures
The PC-PTSD-5 assesses the presence of core PTSD symptoms experienced in the past month, including:
- Intrusive memories or nightmares
- Avoidance of trauma reminders
- Negative thoughts or feelings related to the trauma
- Hyperarousal or excessive startle response
- Functional impact or emotional distress
Each item reflects clinically meaningful symptom domains closely aligned with DSM-5-TR criteria.
Interpretation Guidelines
The PC-PTSD-5 yields a total score between 0–5, based on the number of “Yes” responses.
Recommended cutoff:
- ≥3 indicates a positive screen for probable PTSD and the need for further diagnostic evaluation.
Interpretation Notes:
- A positive screen does not confirm PTSD; the PC-PTSD-5 is a triage tool.
- Use in combination with a full PTSD assessment (e.g., PCL-5) or clinical interview.
- A score of 1–2 may still represent trauma-related distress that warrants further discussion.
- Screening should be contextualized with recent trauma exposure, functional impairment, cultural considerations, and comorbid conditions.
- Avoid administering the tool during acute crisis states where responses may be transiently elevated.
Psychometric Properties
Reliability
- High internal consistency for a 5-item screener
- Strong test–retest stability in primary care and veteran samples
Validity
- Strong sensitivity and specificity at the ≥3 cutoff (Prins et al., 2016)
- Very efficient predictor of PTSD in primary care populations
- Useful across diverse clinical settings and trauma populations
- Validated against criterion-standard PTSD diagnostic interviews including CAPS-5
Administration Considerations
- Designed for primary care and can be administered verbally or via self-report
- Functions as a first-step screener before administering the PCL-5
- Should follow confirmation of a qualifying Criterion A trauma
- May require clinician support for individuals with avoidance, dissociation, or difficulty recalling events
- Works well in brief medical encounters, telehealth, and community health models
Limitations
- Not diagnostic on its own
- May under-identify individuals with avoidance or dissociative presentations
- False positives may occur in the context of depression, anxiety, or acute stress
- Limited detail on symptom severity or functional impairment
- Must be interpreted alongside clinical judgment and complete trauma history

Frequently Asked Questions
How is the PC-PTSD-5 scored?
Each of the 5 items is answered Yes (1) or No (0), yielding a total score of 0–5. The total simply counts the number of Yes responses. No weighting or subscale calculation is required.
What score is considered a positive screen on the PC-PTSD-5?
A score of 3 or more (≥3) is the recommended threshold for a positive screen, indicating probable PTSD and the need for further diagnostic evaluation. This cutoff was established in the original validation study by Prins et al. (2016) in a veteran primary care sample. A civilian primary care study by Williamson et al. (2022) found that a cutoff of 4 optimized sensitivity in that population.
Is the PC-PTSD-5 self-report or clinician-administered?
The PC-PTSD-5 is designed for flexible administration: it can be completed as a patient self-report form or administered verbally by a clinician or staff member. Both formats are appropriate in primary care and integrated care settings.
Can the PC-PTSD-5 diagnose PTSD?
No. The PC-PTSD-5 is a triage screener, not a diagnostic instrument. A positive screen indicates that a fuller evaluation is warranted — typically a structured clinical interview or a comprehensive measure such as the PCL-5. A trained clinician must make any PTSD diagnosis.
