| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Questionnaire |
| Brief Description |
The RADAI and RADAI‐5 are patient‐assessed measures for disease activity in rheumatoid arthritis (RA). Both are 5‐item questionnaires. The items ask about global disease activity in the last 6 months, current disease activity with respect to joint tenderness and swelling, arthritis pain, and duration of morning stiffness. The RADAI also includes tender joints rated on a joint list and the RADAI‐5 asks about general health. The RADAI‐5 is analogous to the RADAI with replacement of joint counts by the patient's general health assessment and slight change of question format. |
| Number of Items | 5 |
| Range | 0-10 |

| Developed for | --- |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score |
All items are scored on a 0–10 ordered category scale. For items 1 and 2, 0 = “completely inactive” and 10 = “extremely active.” For item 3, 0 = “no pain” and 10 = “unbearable pain.” For item 4, 0 = “very good” health status and 10 = “very bad” health status. For item 5, 0 = “no stiffness” and 10 = “stiffness the whole day.” |
| Score Interpretation | 0 means no RA disease activity, with higher scores indicating higher levels of disease activity. |
| Cut-off points | 0.0–1.4 = a remission‐like state, 1.6–3.0 = mild disease activity, 3.2–5.4 = moderate disease activity, and 5.6–10.0 = high disease activity |
| Cut-off points applied to | --- |
| Smallest detectable change if described | 1.4 |
| Smallest detectable change applied to | --- |
| Completion time by the patient | <1 minutes |
| Scoring time by the assessor | <1 minutes |
| Training to score | Not necessary |
| Strengths | Easy to use, Useful in clinical practice & research |
| Limitations | --- |
