Each of the five items scores 0 to 5; their sum (0 to 25) is multiplied by 4 to give a 0–100 percentage score.

“پرسشنامه بهزیستی WHO-5” has 5 questions; every question is required. Question types: Single choice (5). 30 ready-made options across 5 choice questions, all editable in the online version.
Current mental well-being over the last two weeks: good spirits, calm, energy, feeling rested and interest in daily life. All five statements are positive, so a higher score means more well-being. It is used both to measure well-being and to screen for depression.
The WHO-5 measures well-being; a low score is only a signal for further screening, not a diagnosis. This questionnaire is a screening tool, not a diagnosis; only a qualified mental-health professional can diagnose. If you feel severe distress or have thoughts of harming yourself, call Iran's social emergency line 123 or the counselling line 1480 now, or go to the nearest medical centre.
| Score | Level | Suggested action |
|---|---|---|
| 0–28 | Low well-being; likely depression | Professional assessment recommended |
| 29–50 | Low well-being | Screening for depression recommended |
| 51–100 | No sign of reduced well-being | — |
The percentage cut-offs (50 or below to screen for depression, 28 or below for likely depression) come from the systematic review by Topp et al. (2015). At follow-up, a 10-point change is considered meaningful.
