Definition
The PCL-5 (PTSD Checklist for DSM-5) is a self-report instrument developed by the National Center for PTSD to assess post-traumatic stress disorder symptoms. Its 20 items cover the four DSM-5 PTSD symptom clusters: intrusion (items 1-5), avoidance (items 6-7), negative alterations in cognition and mood (items 8-14), and hyperarousal (items 15-20). Each item is scored from 0 (not at all) to 4 (extremely), with a total score of 0 to 80.
Cut-off scores
The National Center for PTSD suggests a provisional cut-off of 31-33 points for PTSD screening in general clinical use. Some specific studies use different thresholds depending on the population. The cut-off should be interpreted in the full clinical context, not in isolation.
It can also be used for provisional DSM-5 diagnosis: moderate symptom (score 2 or above) on at least one intrusion item, one avoidance item, two cognitive/mood alteration items, and two hyperarousal items.
When it is used
- When the client reports history of exposure to a traumatic event (accident, violence, traumatic loss, abuse, disaster).
- In initial assessment when there are intrusion symptoms (flashbacks, nightmares), avoidance of trauma-related stimuli, or persistent hyperarousal.
- In treatment follow-up for PTSD (EMDR, CPT, PE).
- In contexts of complex trauma, gender-based violence, or displacement.
When it is not the right tool
The PCL-5 assesses PTSD, not other trauma presentations. For complex trauma with prominent dissociative symptoms, consider additional instruments (DES-II for dissociation). It is not adequate as the sole suicide risk assessment instrument. If risk is suspected, combine with PHQ-9 item 9.
Important clinical consideration
Administering the PCL-5 can reactivate traumatic material in the client. Administer it in a therapeutic context, with sufficient time to process the emotional response before closing the session. Do not administer by email or platform without subsequent clinical support.
Example of use in session
A therapist works with a client who reports sleep difficulties, frequent startle responses, and avoiding certain places since a traffic accident eight months ago. She administers the PCL-5 in the second session, obtaining a score of 38. She uses the scale to orient the treatment plan toward trauma-based interventions (EMDR or CPT).
