WHO-5 is a concise positive-well-being measure focused on mood, vitality, and interest over the past two weeks. Lower scores indicate poorer well-being and support depression-focused follow-up screening.
Formula: WHO-5 raw total = sum of 5 items (0-25); percentage score = raw total x 4 (0-100).
The WHO-5 is a widely used five-item positive well-being index scored 0-25 (often transformed to 0-100 by multiplying by 4). WHO guidance and validation studies commonly use raw score <13 (or percentage <52) as a threshold for poor well-being warranting further depression-focused assessment.
Lower WHO-5 scores indicate poorer positive well-being and support additional mood-focused assessment.
Use for concise wellbeing tracking in primary care, wellness programs, and mental-health follow-up.
WHO-5 is a positive-wellbeing measure, not a standalone diagnostic psychiatric instrument.
