| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Questionnaire |
| Brief Description |
40 questions scored from 1 to 7 grouped into six subsections: physical functioning, activities, symptoms, treatment, mood, and self-image |
| Number of Items | 49 items |
| Range | Minimum score: 40 and maximum: 280 |
| Responses options/scale |
Yes Seven-point scale |
| Developed for | Not specified |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score |
The authors propose to use the absolute value or to derive the summary score from the sum of the mean of each of the six subsections. Although the authors conclude that the study was not designed to determine if and how the items should be weighted. |
| Score Interpretation | Higher values correspond to worse quality of life |
| Cut-off points | --- |

| Completion time by the patient | - minutes |
| Scoring time by the assessor | - minutes |
| Training to score | Not necessary |
