Assessing eudaimonic well-being in research and clinical settings. PWB-18 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, PWB-18 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.

Add up all the item scores you noted in Step 1.
4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + … (items 9–18 sum to 36) = 68
Find the row in the interpretation table whose range contains your total:
Total = 68 falls between 55 and 80 → Moderate well-being
Moderate well-being. Monitor
A score is one input alongside history and examination. PWB-18 supports clinical judgment — it does not replace it.
Psychometric figures are drawn from the validation literature and may vary across clinical populations and translations.
