| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Composite Index |
| Brief Description |
The Juvenile Arthritis Functional Assessment Report (JAFAR), is a reliable and valid 23-item scale evaluating physical functional ability. There is a parent‐completed version (JAFAR‐P) and a version that can be completed by the child (JAFAR‐C). The JAFAR‐C asks questions of the child the JAFAR‐P is a parent questionnaire |
| Number of Items | 23 |
| Range | Total score for Part I can range from 0 to 46 |
| Responses options/scale |
Yes 3-point scales |
| Developed for | Both |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered, Interviewer/assessor |
| Recommendations to score |
The range of the questions is 0–2. 0 = able to perform tasks All the time; 1 = able to perform the task sometimes; 2 = able to perform the task almost never. By hand, calculate total score for Part I. |
| Score Interpretation | Lower scores indicate better function |
| Cut-off points | --- |
| Cut-off points applied to | --- |
| Smallest detectable change if described | --- |
| Smallest detectable change applied to | --- |
| Completion time by the patient | 10 minutes |
| Scoring time by the assessor | 5-10 minutes |
| Training to score | Not necessary |
| Strengths | Easy to use, Useful in clinical practice & research |
| Limitations | --- |
