How it works
- Answer all 9 questions by selecting how often each symptom has bothered you over the past two weeks.
- Each answer is scored: Not at all = 0, Several days = 1, More than half the days = 2, Nearly every day = 3.

- The score is mapped to a severity category: minimal (0–4), mild (5–9), moderate (10–14), moderately severe (15–19), or severe (20–27).
- Review the suggested clinical action and share the result with your healthcare provider.
