| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Questionnaire |
| Brief Description |
Patient-reported measure of AS-specific quality of life with four domains: physical function, disease activity, emotional well-being and social participation. |
| Number of Items | 20 items (6 items for physical function, 4 items for disease activity, 5 items for emotional well-being, and 5 items for social participation). |
| Range | 0-80 (0-24 for physical function, 0-16 for disease activity, 0-20 for emotional well-being, and 0-20 for social participation). |
| Responses options/scale |
Yes Each question is scored from 0 to 4. Zero indicates “no limitation” increasing to 4 indicating “extreme limitation”. |
| Developed for | --- |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score |
The sum of the individual scores is calculated to give the domain score and the overall index score. |
| Score Interpretation | Higher scores represent worse AS-related health quality of life (and for each domain: worse physical function, higher disease activity, impaired emotional well-being and impaired social participation). |

| Completion time by the patient | 5 minutes |
