24-item measure of peritraumatic distress related to the COVID-19 pandemic. CPDI is part of standard practice in this setting because it provides a structured, replicable assessment that can be tracked over time and compared across patients or visits.
Like all screening or assessment instruments, CPDI is a structured aid — not a diagnostic test in isolation. Results should be interpreted alongside history, examination, and clinical context. Where a score crosses an actionable threshold, the next step is typically a more detailed clinical evaluation rather than a definitive diagnosis.
Answer all 24 items below to see your CPDI score and interpretation.
Each item is scored on a 5-point scale (0–4). Your score updates live as you answer.
All scoring runs in your browser. No data is sent anywhere — close the tab and the answers are gone.
Sum all 24 items scored 0-3. Total range 0-72. Score >= 28 suggests significant distress.
Scoring notes: Sum all 24 items scored 0-3. Total range 0-72. Score >= 28 suggests significant distress.
The cutoffs below are drawn from the published validation literature. Always interpret in clinical context.
| Score range | Band | Interpretation |
|---|---|---|
| 0–27 | Normal | None |
| 28–72 | Significant distress | Consider support |
This is an illustrative walkthrough, not a real patient. Follow the same four steps with your own answers — or use the live calculator at the top of this page.
Read each question and choose the response that best fits. Each response has a number next to it — that number is the item's score. The example below uses illustrative answers.

Add up all the item scores you noted in Step 1.
2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + … (items 9–24 sum to 34) = 50
Find the row in the interpretation table whose range contains your total:
Total = 50 falls between 28 and 72 → Significant distress
Significant distress. Consider support
A score is one input alongside history and examination. CPDI supports clinical judgment — it does not replace it.
Psychometric figures are drawn from the validation literature and may vary across clinical populations and translations.
