| 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 |
| Cut-off points | --- |
| Cut-off points applied to | --- |
| Smallest detectable change if described | --- |
| Smallest detectable change applied to | --- |
| Completion time by the patient | <5 minutes |
| Scoring time by the assessor | <1 minutes |
| Training to score | Not necessary |
| Strengths | Easy to use |
| Limitations | --- |
