DESCRIPTION OF THE INSTRUMENT
Type Of Measure Questionnaire
Brief Description

The HAQ-II was developed to assess functional status in individuals with rheumatic disease. It was intended to be a short replacement for the HAQ. Content: ten items regarding daily activity: toileting, opening doors, standing from a chair, walking on flat ground, waiting in line, reaching for an object, ambulating up steps, performing outdoor work, lifting heavy objects, and moving heavy objects.

Number of Items 10 items (5 from the original HAQ and 5 additional items).
Range 0-3
Responses options/scale Yes
and 3 = unable to do.
Developed for Both
PRACTICAL APPLICATION
Method of administration Interviewer/assessor, Self-administered
Recommendations to score

The HAQ-II may be calculated by hand or with a calculator by adding all scored items together (at least 8 of the 10 items are required) and dividing by the total number of items answered to obtain the final score.

HAQ-II scores are nonlinear and a change from 0 to 1 may not indicate the same amount of functional change as a change from 2 to 3. Conversion formula exist to transform HAQ-II into HAQ scores. 

Score Interpretation higher scores indicate worse function and greater disability
