HAQ: track your physical function

The Health Assessment Questionnaire Disability Index (HAQ-DI) is the most widely used measure of physical function in rheumatoid arthritis. It asks how much difficulty you have had over the past week with everyday activities, across eight areas from dressing to walking to grip. Complete it, save your result to track it over time, and print it to bring to your rheumatology appointment.

Answer all eight sections above to see your score.
About the score. HAQ-DI runs from 0 to 3, where a higher number means more difficulty with daily activities. Each of the eight areas is scored by its hardest activity, and the eight are averaged. If you use aids or need help from another person for an area, that area counts as at least 2. Any single score is one data point for a conversation with your team, not a diagnosis or a treatment decision on its own; function can also be affected by joint damage, age, and other conditions, not only by active arthritis.

How the score is worked out

Each of the eight areas (dressing and grooming, arising, eating, walking, hygiene, reach, grip, and everyday activities) is scored from 0 to 3 by its most difficult activity. If you use an aid or device, or need help from another person, that area is scored as at least 2. The HAQ-DI is the average of the eight areas, giving a 0 to 3 result. A change of about 0.22 or more is generally considered a meaningful change in rheumatoid arthritis.
