Abstract
Objective
This study aimed to translate and culturally adapt the standardized outcomes in nephrology–hemodialysis fatigue (SONG–HD fatigue) scale and to assess the psychometric properties of the Chinese version of the SONG–HD fatigue (C-SONG–HD fatigue) scale.
Methods
Forward and back translations were used to translate the SONG–HD fatigue scale into Chinese. We used the C-SONG–HD fatigue scale to survey Chinese patients undergoing hemodialysis (HD) in China. We examined the distribution of responses and floor and ceiling effects. Cronbach’s alpha and McDonald’s omega coefficient, intraclass coefficients, and Spearman correlations were used to assess internal consistency reliability, test–retest reliability, and convergent validity, respectively. Responsiveness was also evaluated.
Results
In total, 489 participants across southeast China, northwest China, and central China completed the study. The C-SONG–HD fatigue scale had good internal consistency (Cronbach’s alpha coefficient 0.861, omega coefficient 0.916), test–retest reliability (intraclass correlation coefficient 0.695), and convergent validity (Spearman correlation 0.691). The analysis of all first-time HD patients did not show notable responsiveness, and only patients with temporary vascular access had good responsiveness with an effect size (ES) of 0.54, a standardized response mean (SRM) of 0.85, and a standard error of measurement (SEM) of 0.77.
Conclusion
The Chinese version of the SONG–HD fatigue scale showed satisfactory reliability and validity in patients undergoing hemodialysis (HD) in China. It could be used as a tool to measure the fatigue of Chinese HD patients.
