| Brief Description |
The aim of this study was to establish the cutoff points in the Combined Index of Fibromyalgia Severity (ICAF) questionnaire which allow classification of patients by severity and to evaluate its application in the clinical practice. |

| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Questionnaire |
| Brief Description |
The ICAF evaluates the main fibromyalgia symptoms in five domains: emotional (anxiety and depression), physical (pain, fatigue, sleep quality, and functional capacity), active coping (positive coping strategies), and passive coping. |
| Number of Items | 59 |
| Range | 0-84 |
| Responses options/scale |
No |
| Developed for | Clinical practice |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score | --- |
| Score Interpretation | The higher the score, the worse. In the ICAF scoring sheet, besides the direct score, Z score and T score are expected to be calculated, based on Vallejo 2010 |
| Cut-off points | --- |
| Cut-off points applied to | --- |
| Smallest detectable change if described | --- |
| Smallest detectable change applied to | --- |
| Completion time by the patient | 0 minutes |
| Scoring time by the assessor | 0 minutes |
| Training to score | Not necessary |
| Strengths | Useful in clinical practice & research |
| Limitations | Complex scoring, Lengthy |
| OTHER COMMENTS | |
| Other Comments |
With the exception of the passive coping factor, all the other scores, including the overall score, were sensitive to change after the therapeutic intervention. The ICAF scores of the patients with fibromyalgia compared with those of the control group were markedly different. |
