Objective: To validate translated Turkish version of the Fibrofatigue Scale FFS. Methods: The Turkish version of FFS was administered to a consecutive sample of 82 patients with fibromyalgia syndrome FMS; 78 women; mean age was 37 years and mean symptom duration was 2.3 years. The Turkish version of the Fibromyalgia Impact Questionnaire, the Beck Depression Inventory BDI, and the Medical Outcome Survey Short Form-36 SF-36 were documented. Reliability was tested by the test-to-test reliability intraclass correlation coefficient and internal consistency Cronbach's alpha coefficients. Construct validity was assessed by association with BDI and SF-36 Spearman's correlation coefficient. Paired t-test was used to determine the statistical significance of change score responsiveness. Results: The testretest reliability and internal consistency of the FFS were excellent with intraclass correlation coefficient of 0.98 0.970.99 and Cronbach's alpha of 0.74. The correlations between the FFS and the Fibromyalgia Impact Questionnaire items rho 0.56, BDI rho 0.52, and subscales of SF-36 rho value ranging from -0.333 to -0.553 were adequate. The FFS score improved significantly after a four-week physical therapy program P < 0.001. Conclusions: The Turkish FFS is a reliable and valid instrument for detecting and measuring functional disability and symptom severity in Turkish patients with FMS. © 2010 Informa Healthcare USA, Inc.
