Abstract
The aim of this study was to evaluate the psychometric properties of the Brief Fatigue Inventory (BFI) in hemodialysis patients. During a dialysis day, patients completed both 9-item BFI and 21-item Beck Depression Inventory (BDI)-II questionnaires. The psychometric properties of the BFI were assessed in terms of reliability and validity. The BFI had an overall Cronbach’s coefficient alpha of.92. Inter-item correlation coefficients between BFI items ranged from.38 to. 81 (all p <.0001). Exploratory factor analysis revealed bidimensional factor structure of the BFI—fatigue “severity” and fatigue “interference” explaining 11.0% and 62.0% of the total variance in the data set, respectively. In criterion validity analysis, BFI composite score correlated significantly with the total BDI-II score—Pearson correlation coefficient.40 (p <.0001). These preliminary results support the satisfactory psychometric properties of the BFI in assessing fatigue among hemodialysis patients during a dialysis day in a clinic setting.
