How it works

  1. Select how often each of the 9 symptoms has bothered you over the past two weeks.
  2. Scores are assigned: Not at all = 0, Several days = 1, More than half the days = 2, Nearly every day = 3.
  3. Your total score (0–27) updates automatically as you answer each item.
  4. The score maps to a severity category: minimal (0–4), mild (5–9), moderate (10–14), moderately severe (15–19), or severe (20–27).
  5. A suggested clinical action and per-item breakdown are shown alongside the result.
  6. Share or print the results panel to bring to a healthcare appointment.
