What is HAQ?

You are here:

The Health Assessment Questionnaire (HAQ), is a tool for measuring functional status in rheumatology. The original assessment was 32 questions long which prompted a new version to be developed.

The HAQ-II (download here) is a 10-item questionnaire used to measure disability or physical function in patients with rheumatic diseases. To score, just sum all the scores of each question (a minimum of 7 must be answered), and divide by the total number of questions answered to get a value between 0 (minimal loss of function) and 3 (completely disabled).
