| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Composite Index |
| Brief Description |
The JSpADA is the first disease activity assessment tool developed and validated for use in juvenile spondyloarthropathies, including the ERA category of JIA. This index includes the count of active joints and tender entheses, the clinical evaluation of sacroiliitis, the presence of morning stiffness, patient assessment of pain, the presence of uveitis, the evaluation of back mobility, and the assessment of inflammatory markers |
| Number of Items | 8 |
| Range | 0-8 |
| Responses options/scale |
Yes - |
| Developed for | Clinical practice, Research |
| PRACTICAL APPLICATION | |
| Method of administration | Physician, Self-administered |
| Recommendations to score |
Active joint count includes any involved joint; 0 points are given if no joint is affected, 0.5 points if one to two joints are affected, and 1 point if three or more joints are affected. Active entheses count includes any involved entheses; 0 points are given if no enthesis is affected, 0.5 points if one to two entheses are affected, and 1 point if three or more entheses are affected. Pain is recorded on a 0 to 10 VAS; 0 points are given if the VAS score is 0, 0.5 points if the VAS score is 1 to 4, and 1 point if the VAS score is more than 4. ESR and CRP level, if related to ERA activity, are scored as 0 if within normal range, as 0.5 if up to twice the upper normality level, and as 1 if the ESR or CRP value is above twice the upper normality level. Morning stiffness is scored as 0 if absent or present for up to 15 minutes and as 1 if present for longer than 15 minutes. Clinical sacroiliitis is defined as the absence (0 points) or presence (1 point) of two or more of the following: tenderness on examination, positive Patrick’s test or flexion abduction external rotation test, and inflammatory back pain. Uveitis (including acute/symptomatic and chronic/asymptomatic disease) is scored 1 point if present or 0 points if absent. Finally, abnormal back mobility, defined as a modified Schober’s test of less than 20 cm, is scored 1 point if present or 0 points if absent. |
| Score Interpretation | Higher scores indicate higher disease activity |
| Cut-off points | No threshold values for score interpretation have been provided yet |
| Cut-off points applied to | --- |
| Smallest detectable change if described | --- |
| Smallest detectable change applied to | --- |
| Completion time by the patient | - minutes |
| Scoring time by the assessor | - minutes |
| Training to score | Training is necessary for reliable assessment of joint/enthesis counts and for assessment of sacroiliitis and Schober’s test. |
| Strengths | Useful in clinical practice & research, Easy to use |
| Limitations | --- |
