| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Questionnaire |
| Brief Description |
The SIQR is the disease-neutral revision of the updated FIQ, that measures physical functioning, work status, depression, anxiety, sleep, pain, stiffness, fatigue, and well being. It is identical to FIQR but does not contain any specific reference to FM. It consists of three domains: Function (nine items), Overall Impact (two items) and Symptoms (ten items) that are scored on a scale from 0 to 10, with 10 being the most severe. The SIQR assesses disease activity in patients with rheumatic disorders. |
| Number of Items | 21 |
| Range | 0-10 |
| Responses options/scale |
Yes Scale from 0 (no difficulty/ never) to 10 (very difficult/ always) |
| Developed for | Both |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score |
In the questionnaire, the patient is asked to place an "X" in the box for each question that best indicates how much difficulty they have experienced in doing the activities during the past 7 days., the impact of their medical problems and the intensity of the symptoms. After that, there are just 3 steps in scoring: 1. Sum the scores for each of the three domains (function, overall, and symptoms 2. a. Divide function domain sum (0-90) by 3 (upper limit 30) 3. Add the three resulting domain scores (a, b and c) to obtain the total score of the SIQR (range 0 -100). |
| Score Interpretation | Higher scores indicate higher impact |
| Cut-off points | Low severity (range 0-29), moderate severity (range 30–59 and high severity (range 60-100) |
| Cut-off points applied to | Not specified |

| Completion time by the patient | - minutes |
