Key Points

To evaluate the validity and reliability of the Multidimensional Fatigue Inventory-20 (MFI-20) for assessing fatigue dimensions in female patients with fibromyalgia.
Enrolled 120 female outpatients (mean age 45±9.1 years; range, 20 to 60) diagnosed with fibromyalgia according to 1990 and 2010 ACR criteria.
Conducted forward-backward translation of the MFI-20 and evaluated test-retest reliability across a 48-hour interval.
Assessed structural validity using confirmatory factor analysis, internal consistency with Cronbach alpha, and convergent validity against FIS, VAS-pain, VAS-fatigue, and SF-36 questionnaires.
Demonstrated high internal consistency with a total Cronbach alpha of 0.92 (subscale range, 0.78 to 0.93) and a test-retest intra-class correlation coefficient of 0.934.
Confirmatory factor analysis confirmed good structural validity across five fatigue dimensions.
Revealed strong convergent validity, with all correlation coefficients between MFI and FIS exceeding 0.80.
