PCL-5: PTSD Screening
The PCL-5 (PTSD Checklist for DSM-5) is a 20-item self-report measure for assessing PTSD symptom severity across all four DSM-5 symptom clusters, scored 0-80.
What Is the PCL-5?
The PTSD Checklist for DSM-5 is the standard self-report measure for trauma-related symptom severity. Twenty items map to the four DSM-5 PTSD symptom clusters, each scored from 0 (not at all) to 4 (extremely), yielding a total score of 0-80.
Scoring and Clinical Cutoffs
- Provisional PTSD diagnosis: Total score of 31-33 (the commonly used clinical threshold)
- Sub-clinical: Scores below 31
- Reliable change index: 10+ points indicates clinically meaningful change
Symptom Cluster Subscales
| Cluster | Items | DSM-5 Criteria |
|---|---|---|
| Intrusion | 1-5 | Re-experiencing the event |
| Avoidance | 6-7 | Avoiding reminders |
| Negative cognitions/mood | 8-14 | Negative thoughts and feelings |
| Arousal/reactivity | 15-20 | Hypervigilance and reactivity |
Subscale scores are often more clinically useful than the total. A client whose avoidance subscale drops while intrusion symptoms hold steady indicates that exposure work is having targeted effect.
Clinical Applications
Trauma Treatment Monitoring
Administer at intake, then every 2-4 sessions during trauma-focused therapy (EMDR, CPT, PE). Track subscale patterns to inform treatment focus and document progress toward treatment plan objectives.
Documentation
Reference PCL-5 scores in progress notes: “PCL-5 total decreased from 58 to 42 (session 8). Intrusion subscale shows most improvement (22 to 12); avoidance subscale remains elevated (7 to 6).”
Practical Tips
- Administration time: 5-7 minutes
