AB  - Objective: This study aimed to validate the Danish versions of the Bristol 
      Rheumatoid Arthritis Fatigue Multi-Dimensional Questionnaire (BRAF-MDQ) and BRAF 
      Numerical Rating Scale version 2 (NRSv2).Method: We tested face and content 
      validity, internal consistency, criterion validity, construct validity, and 
      reproducibility for the BRAF-MDQ, and face and criterion validity and 
      reproducibility for the BRAF-NRS.Results: In all, 224/236 patients (95%) 
      completed the questionnaires [70% female, mean +/- sd age 59 +/- 13.04 years, disease 
      duration 11.2 +/- 9.49 years, Health Assessment Questionnaire (HAQ) 0.724 +/- 0.70, 
      and 28-joint Disease Activity Score-C-reactive protein 2.55 +/- 1.24]. The 
      unidimensionality for the physical and cognitive fatigue subscales was confirmed, 
      whereas the living with fatigue and emotional fatigue subscales were not 
      unidimensional. Cronbach's alpha was 0.94 for the BRAF-MDQ total and 0.78-0.92 for 
      the four subscales. The correlations between BRAF-MDQ and various measures were: 
      36-item Short Form Health Survey (SF-36) vitality subscale, 0.75; Hospital 
      Anxiety and Depression Scale (HADS) anxiety subscale, 0.65; HADS depression 
      subscale, 0.62; visual analogue scale (VAS) pain, 0.62; VAS global, 0.73; and 
      HAQ, 0.62. The intraclass correlation coefficient for agreement was 0.995. A 
      Bland-Altman plot showed a mean +/- sd difference of -1.9 +/- 3.62 for BRAF-MDQ. 
      Correlation coefficients between the BRAF-NRSv2 subscales and other subscales 
      were: BRAF-MDQ subscales, 0.57-0.93; SF-36 vitality subscale, 0.54-0.68; and VAS 
      fatigue, 0.66-0.82.Conclusions: The Danish BRAFs are considered valid and 
      reliable for use among Danish patients with rheumatoid arthritis, despite the 
      subscales living with fatigue and emotional fatigue not being unidimensional, as 
      they are in the original version.
