Bath Ankylosing Spondylitis Disease Activity Index: BASDAI
The BASDAI is a validated diagnostic test and is often used to determine the effectiveness of the drug therapy or to indicate the need for a new drug therapy for the treatment of Ankylosing Spondylitis (AS). 

Instructions:
Please answer the questions below relating to the past week.

Conditional information

How this model should be used:
The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) disease activity questionnaire contains six questions regarding subjective symptoms during the week prior to answering the above six questions.


Evaluation of model performance:
The BASDAI was found by patients to be quick and simple to complete (mean: 67 s). Test-retest reliability was good (r = 0.93; p < 0.001), as was the distribution of scores across the scale (score range: 0.5-10; mean: 4.31). BASDAI was sensitive to change, reflecting a 16% (mean) improvement in inpatient scores after 3 weeks of treatment. It is superior to the DAI in terms of construct and content validity and to the Enthesis Index in all aspects.
