| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Scale |
| Brief Description |
LFIS-RA evaluates the efficacy of multidisciplinary foot‐health care in rheumatoid arthritis. There are two subscales: impairment/footwear (21 items) and activity limitation/participation restriction (30 items). |
| Number of Items | 51 |
| Range | 0-51 |
| Responses options/scale |
Yes “True” and “not true.” |
| Developed for | Clinical practice, Research |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score |
A “true” response is scored as 1 point, and a “not true” response is scored as 0. Item scores in each subscale are then totaled to provide separate subscale scores that can be summated to provide an overall score (maximum overall score of 51). |
| Score Interpretation | A higher score indicates greater disability |
| Cut-off points | > 7 on the impairment/footwear= moderate-high levels of foot impairment; >10 on the activity limitation/participation restriction =moderate-high levels of foot disability |
| 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 | Self‐study of the scoring documentation minutes |
| Training to score | Not necessary |
| Strengths | Useful in clinical practice & research |
| Limitations | --- |
| OTHER COMMENTS | |
| Other Comments |
LFIS‐RA has been used in patients with psoriatic arthritis, gout, and systemic lupus erythematosus, although its psychometric properties in conditions other than rheumatoid arthritis have not been evaluated. |
