About this Calculator

The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) disease activity questionnaire contains six questions regarding subjective symptoms during the week prior to answering the questions.

  • 1. How would you describe the overall level of fatigue/tiredness you have experienced?
  • 2. How would you describe the overall level of AS neck, back, or hip pain you have had?
  • 3. How would you describe the overall level of pain/swelling in joints other than neck, back, hips you have had?
  • 4. How would you describe the level of discomfort you have had from an area tender to touch or pressure?
  • 5. How would you describe the level of morning stiffness you have had from the time you wake up?
  • 6. How long does your morning stiffness last from the time you wake up?

Each question is scored on a scale of 0 to 10. Aside from the last question, 0 indicates none and 10 indicate very severe. For the last question, 0 is 0 hours, 5 is one hour, and 10 is two or more hours.

To calculate the BASDAI score, the forumula is:

BASDAI = ((Q1 + Q2 + Q3 + Q4) + ((Q5 + Q6) / 2)) / 5
