PCL-5 — PTSD Checklist for DSM-5

The PCL-5 is the dominant self-report measure of DSM-5 PTSD severity. If you do trauma-focused work — EMDR, CPT, prolonged exposure, written exposure therapy — this is the instrument you’ll administer most often. Twenty items, one month look-back, mapped one-to-one to DSM-5 PTSD symptoms across four diagnostic clusters. US Department of Veterans Affairs publication, public domain.

​

What it measures

DSM-5 PTSD symptom severity, organized into the four diagnostic clusters:

• Cluster B — Intrusion (items 1-5). Memories, dreams, flashbacks, upset reactions to reminders, physical reactions.
• Cluster C — Avoidance (items 6-7). Avoiding internal reminders, avoiding external reminders.
• Cluster D — Negative cognition and mood (items 8-14). Amnesia, negative beliefs, blame, negative emotions, anhedonia, detachment, emotional numbing.
• Cluster E — Arousal and reactivity (items 15-20). Irritability, risk-taking, hypervigilance, exaggerated startle, concentration problems, sleep disturbance.

The items reference “the stressful experience.” Before administering, anchor the client to a specific index trauma — the PCL-5 quantifies symptoms, it doesn’t characterize the event.

​

When to use it

• Trauma-focused intake to establish a PTSD baseline.
• Every 4-8 sessions during trauma-focused treatment to track trajectory.
• Pre/post a discrete protocol (8-session CPT, full EMDR reprocessing of a target, completed prolonged exposure).
• Discharge documentation to record outcome.

​

How clients fill it out

Twenty items rated 0-4 (Not at all → Extremely). Five to seven minutes. Reading level grade 6-7. In Rivet, the client answers on your screen in-session or via a link async. The four cluster subscales surface alongside the total as soon as scoring completes.

​

Scoring and severity cutoffs

​

Total score

Sum of all 20 items. Range 0-80. A total of 33 or higher is the cutoff for probable PTSD in civilian samples (Bovin et al. 2016 — veteran samples use 31). Rivet uses ≥33 as the surface flag.

​

DSM-5 cluster algorithm

A symptom is counted as “endorsed” when rated 2 or higher (Moderately or above):

• Cluster B (items 1-5): ≥1 item endorsed
• Cluster C (items 6-7): ≥1 item endorsed
• Cluster D (items 8-14): ≥2 items endorsed
• Cluster E (items 15-20): ≥2 items endorsed

When all four clusters meet criteria → provisional DSM-5 PTSD diagnosis. The cluster algorithm is documented in the template and the cluster subscales show on the result, but the strict per-item endorsement check is something you apply by inspecting responses — Rivet doesn’t auto-render a “provisional PTSD” banner.

​

Clinical change

A 5-10 point drop is the practitioner convention for clinically meaningful improvement (Wortmann et al. 2016 lands on 10 points as the stronger signal; the 5-point benchmark is the looser response threshold often used between sessions). A total ≥ 50 indicates severe PTSD symptomatology.

​

Risk flagging

The PCL-5 doesn’t include a suicide item. Trauma populations carry elevated suicide risk independent of total score — pair with C-SSRS at intake and at any inflection point in treatment.

​

PCL-5 vs ITQ, CPSS-5 and ACE

The PCL-5 is the adult DSM-5 measure. Each of the others answers a different question.

• vs ITQ — the two diagnostic systems parted ways in 2019, when ICD-11 recognised Complex PTSD as a distinct condition and DSM-5 did not. The PCL-5 maps DSM-5; the ITQ maps ICD-11 and is the instrument that separates PTSD from CPTSD. If the history is chronic or developmental and the presentation includes affect dysregulation, negative self-concept and difficulty staying close to people, the ITQ is asking about that directly and the PCL-5 isn’t.
• vs CPSS-5 — the same DSM-5 criteria written for ages 8 to 18. Use it for anyone in that range; the PCL-5 was validated in adults.
• vs ACE — not a comparison so much as a different axis. The ACE counts categories of childhood adversity, once; the PCL-5 measures current symptom severity and is meant to be repeated. A high ACE score is not a PTSD score.

The PCL-5 also quantifies symptoms without characterising the index trauma — you name the event with the client before they fill it in, and that conversation is not something the instrument does for you.

Is it free to use?

Yes. A work of the US Department of Veterans Affairs’ National Center for PTSD, and therefore public domain.

When not to use it

• The diagnostic frame is ICD-11, not DSM-5. Use the ITQ — it maps ICD-11 PTSD and adds Complex PTSD.
• You’re assessing a child or adolescent. Use the CPSS-5.
• You haven’t established an index trauma yet. PCL-5 items presume one. Do the trauma history first.
• You want to characterize what happened, not how it affects the client now. PCL-5 is symptom severity only — it doesn’t catalog events.
