What does the PCL-5 measure?

The PCL-5 measures the 20 DSM-5 PTSD symptoms across four clusters: Intrusion (B), Avoidance (C), Negative alterations in cognition and mood (D), and Alterations in arousal and reactivity (E).

What is the cut-point for a positive PTSD screen?

Research suggests a provisional positive screen at a total score of 31–33. Some studies use 33 as the cut-point. A score at or above this threshold warrants further evaluation by a qualified clinician.

Is this tool a clinical diagnosis?

No. This tool is for informational and screening purposes only. Only a licensed healthcare professional can diagnose PTSD. If you are in distress, please seek help immediately.

What are the four DSM-5 symptom clusters?

Cluster B (Intrusion) = items 1–5; Cluster C (Avoidance) = items 6–7; Cluster D (Negative cognitions/mood) = items 8–14; Cluster E (Arousal/reactivity) = items 15–20.

Can I use the symptom cluster method instead?

Yes. The DSM-5 symptom-cluster scoring method counts an item as positive if rated 2 (Moderately) or higher, then requires at least 1 B item, 1 C item, 2 D items, and 2 E items. This tool shows both the total score and cluster subtotals to support either method.
