PC-PTSD-5: Primary Care PTSD Screen for DSM-5

The Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) is a 5-item screening questionnaire developed by the National Center for PTSD at the U.S. Department of Veterans Affairs. Designed specifically for rapid screening in primary care and other medical settings, it helps identify individuals who may have PTSD and would benefit from further evaluation.

Why the PC-PTSD-5 matters: PTSD often goes undetected in primary care settings because patients may not connect their symptoms to past traumatic experiences, or clinicians may not have time for comprehensive assessments. The PC-PTSD-5 provides a quick, validated method to identify probable PTSD in just 1-2 minutes, enabling appropriate referrals for comprehensive evaluation.

DSM-5 Alignment: The PC-PTSD-5 was updated from the original 4-item PC-PTSD to align with DSM-5 diagnostic criteria. The five items assess key PTSD symptom domains:

• Re-experiencing (Item 1): Intrusive memories and nightmares
• Avoidance (Item 2): Avoiding trauma-related thoughts and reminders
• Hyperarousal (Item 3): Hypervigilance and startle response
• Numbing (Item 4): Emotional detachment and disconnection
• Negative cognitions (Item 5): Guilt and distorted blame (new in DSM-5)

Validation and reliability: The PC-PTSD-5 demonstrates excellent diagnostic accuracy. In validation studies with VA primary care patients, a cut-off score of 3 achieved 95% sensitivity and 85% specificity with an area under the curve (AUC) of 0.941. This means the screen correctly identifies most people with PTSD while minimizing false positives.

When to use the PC-PTSD-5: This brief screener is ideal for:

• Initial triage in primary care settings
• Emergency department screening
• Community health screenings
• Annual wellness visits
• Any situation requiring rapid PTSD assessment

For comprehensive symptom assessment and treatment monitoring, the longer PCL-5 (PTSD Checklist) provides more detailed information including symptom severity and cluster subscores.

Important disclaimer: The PC-PTSD-5 is a screening tool, not a diagnostic instrument. A positive screen indicates probable PTSD that warrants comprehensive evaluation by a qualified mental health professional.

Reference: This assessment is based on the official PC-PTSD-5 from the National Center for PTSD. The measure is in the public domain and may be used without permission.

The PC-PTSD-5 begins by asking whether you have ever experienced a traumatic event. Traumatic events include:

• Serious accidents or injuries
• Physical or sexual assault
• Natural disasters (earthquakes, floods, fires)
• War or combat exposure
• Witnessing someone being seriously injured or killed
• Learning about the violent or sudden death of a loved one

If you have experienced trauma, you'll answer 5 yes/no questions about symptoms you've experienced in the past month related to that trauma.

The 5 symptom areas assessed:

1. Intrusive thoughts and nightmares - Unwanted memories or dreams about the traumatic event(s)
2. Avoidance - Actively trying not to think about the event or avoiding reminders
3. Hypervigilance - Being constantly on guard, watchful, or easily startled
4. Emotional numbing - Feeling detached from people, activities, or surroundings
5. Guilt and blame - Feeling guilty or blaming yourself or others for the event or its consequences

Scoring: Each "Yes" answer counts as 1 point, producing a total score from 0 to 5. A score of 3 or higher indicates a positive screen for probable PTSD.

Most people complete this screening in 1-2 minutes.

Scoring Overview:

The PC-PTSD-5 uses simple yes/no responses. Count the number of "Yes" answers to determine the total score (0-5).

Score of 0-2 (Negative Screen):

A score below 3 indicates that PTSD is unlikely based on this screening. However, this does not rule out other mental health concerns or subclinical trauma symptoms that may still benefit from support. If you're experiencing distress related to past experiences, consider discussing this with a healthcare provider.

Score of 3-5 (Positive Screen):

A score of 3 or higher indicates probable PTSD and warrants comprehensive evaluation. Research shows this cut-off achieves:

• 95% sensitivity (catches most true cases)
• 85% specificity (reasonable false positive rate)
• 86% overall diagnostic efficiency

What a positive screen means:

A positive PC-PTSD-5 does not diagnose PTSD. It indicates a high likelihood that a comprehensive clinical evaluation would confirm PTSD. Recommended next steps include:

1. Complete the full PCL-5 - The PTSD Checklist for DSM-5 provides detailed symptom severity and cluster subscores
2. Seek professional evaluation - A structured clinical interview (such as the CAPS-5) can confirm diagnosis
3. Consider treatment options - Evidence-based treatments like Cognitive Processing Therapy (CPT), Prolonged Exposure (PE), and EMDR are highly effective for PTSD

Cut-off considerations:

While a cut-off of 3 is recommended for general screening (maximizing sensitivity), some contexts may warrant different thresholds:

• Cut-off of 4: Better balances sensitivity (83%) and specificity (91%), reducing false positives
• Cut-off of 3 for women: Research suggests women may be underdetected at higher cut-offs
