Fatigue is a prevalent symptom experienced by patients receiving hemodialysis. The purpose of this study was to develop a scale of hemodialysis-related fatigue. The dimensions of fatigue were first identified based on a literature review, which was used to form 37 items as a pool and were administered on 204 hemodialysis patients recruited from three hemodialysis centers located in southern Taiwan. Twenty-six items were extracted based on the result of factorial analyses that were categorized into five factors: ”reduction in vigor and motivation”, ”reduction in physical ability”, ”reduction in mental ability”, ”reduction in daily activities”, ”distress and loss of control in mood.” These five factors well explained 50.19% of the total variance. The Cronbach's α coefficient of the total scale, consisting of 26 items, was 0.91, while the Cronbach's α coefficients of the five subscales were in the range from 0.72 to 0.85. The correlation coefficient of hemodialysis fatigue scale with the fatigue visual analogue scale was 0.64 (P＜.01). Results showed that this new scale had good reliability and validity. It suggested that this scale is appropriate used for an assessment tool to screen the hemodialysis patients with fatigue, and therefore to further provide interventions to decrease the impact of fatigue on the quality of lives of hemodialysis patients.
