Up to 98% of rheumatoid arthritis (RA) patients experienced fatigue. It is an important physical and cognitive symptom which has overwhelming, uncontrollable and unpredictable affects throughout their whole life. RA fatigue composes of complex and multidimensional components which are pain, stress, depression, inflammation and disability. The acknowledgement of fatigue is important and fatigue should be measured in all RA trials alongside the core set. The aim of this study was to determine reliability and validity of Turkish Bristol Rheumatoid Arthritis Fatigue Multidimensional Questionnaire in RA patients. One hundred RA patients were evaluated in the study. Exclusion criteria was determined as patients with cognitive impairment, illiterated patients, unable to understand and speak Turkish, under- 18 and over- 75. To validate Turkish version of BRAF-MDQ (BRAF-MDQ-T), all participants answered BRAF-MDQ-T, Multidimensional Assessment of Fatigue (MAF) scale and Short Form 36 vitality (SF 36 VT). BRAF-MDQ-T was applied again seven days later for test - retest reliability. Validity, internal-consistency and test-retest results were based on a sample 100 patients. Internal consistency reliability of BRAF-MDQ-T was Cronbach α =0,95 which was excellent. The correlations between the total scores of the BRAF-MDQ-T scale and the total scores of MAF-T were positively and statistically significant (r=0.82, p<0.001). The correlations between the total scores of the BRAF-MDQ-T scale and the subscale scores of SF 36 VT were negatively and statistically significant (r=-0.64, p<0.001).The BRAF-MDQ-T was a valid and reliable scale for assessing fatigue in turkish rheumatoid arthritis patients.
