The WHO-5 Well-Being Index is a short, open-access questionnaire promoted by the World Health Organization to measure current subjective psychological well-being. It asks about the past two weeks using a 0-5 scale (from 'At no time' to 'All of the time'). Scores range from 0 to 25. Source: Topp et al., 2015 (PubMed).
How to use it: Think about the last two weeks and rate each statement honestly. It is a quick check-in, not a test you pass or fail.
Reading your score: Higher scores mean better well-being. A low score is a signal to pay attention to your mood, not a diagnosis.
Limitations: The WHO-5 is a screening tool, not a diagnosis. It is self-reported and can be influenced by your mood on the day you take it. It does not replace a clinical evaluation.
When to seek help: If your well-being score is low or your mood worries you, consider speaking with a mental health professional. If you ever feel you might harm yourself, contact a crisis line such as 988 (US) right away.
