| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Questionnaire |
| Brief Description |
The Compliance-Questionnaire-Rheumatology (CQR) is a rheumatology-specific instrument that measures patient compliance to drug regimens, identifies factors that contribute to suboptimal patient compliance, and possibly can be used to predict future compliance in patients with rheumatoid arthritis (RA), polymyalgia rheumatica (PMR), and gout. |
| Number of Items | 19 |
| Range | --- |
| Responses options/scale |
Yes The answers are scored on a 4-point Likert scale with anchors: 1. don’t agree at all; 2. don’t agree; 3. agree; 4. agree very much. |
| Developed for | --- |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score |
The CQR total score is calculated by summing the items, subtracting 19, and dividing by 0.57. |
| Score Interpretation | The CQR total score can vary from 0 (complete noncompliance) to 100 (perfect compliance). |
| Cut-off points | --- |
| 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 | Not necessary |
| Strengths | Useful in clinical practice & research |
| Limitations | --- |

| Other Comments |
A shortened version of the CQR (CQR-5) was created, maintaining a good level of reliability and validity for a short, self-administered, self-report questionnaire.
