Objective:
To obtain an updated FIQ consensus version for patients in Spain, the Cuestionario de Impacto de la Fibromialgia (CIF).
Material And Methods:
The CIF elaboration was carried out with the participation of all the groups of researchers in the 4 previous FIQ Spanish versions, and taking into account the recent updated version of the original FIQ. The CIF was completed by a sample of fibromialgia patients to explore how comprensible its items are and to compare its global score with 2 fibromialgia composite severity indexes, one semi-objective and one subjective. The corresponding Spearman correlation coefficients were determined
Results:
The main modifications introduced in the questionnaire are shown. Some patients were confused in their responses to subitem "j" and item 3, but not with regard to the remaining items or subitems. Correlation coeficients between the CIF and the semi-objective and subjective fibromialgia severity indexes were 0.57 and 0.76 respectively (P<001).
Conclusion:
The CIF is proposed as an updated Spanish version of the FIQ.
