Abstract

Background

Fatigue is a prevalent symptom among patients undergoing hemodialysis, significantly impacting their quality of life. There are several instruments to measure fatigue. However, most of these instruments measure general fatigue, with no specific emphasis on fatigue related to hemodialysis. Recently, a validated scale, the Post-Dialysis Fatigue (PDF) scale, was developed to address this gap by directly measuring post-dialysis fatigue.

Objectives

The aim of this study was to translate the English version of the PDF scale into Vietnamese and to examine its reliability and validity, taking into account potential cultural differences in the experience of fatigue.

Design

A cross-sectional study was applied with participants obtained through convenience sampling at two hospitals.

Participants

Three hundred and twenty-eight participants undergoing hemodialysis treatment were recruited.

Measurements

The validity of the 13-item Vietnamese version of Post-Dialysis Fatigue scale was evaluated by examining the content validity, concurrent validity, and construct validity. Both exploratory and confirmatory factor analyses were employed to factorize the underlying structure of the scale and confirm whether the data fit a hypothesized measurement model. The reliability was examined by using Cronbach's alpha and test-retest reliability.

Results

The scale had an excellent content validity index (CVI: 0.86–1.00), good internal consistency (Cronbach's alpha of 0.90), and acceptable test-retest reliability (interclass correlation coefficient of 0.84). Exploratory factor analysis constituted two factors (behavioral fatigue and sensory fatigue) accounting for 59.38% of the variance. The confirmatory factor analysis showed a good model fit (CFI = 0.952, NFI = 0.912, RMSEA = 0.073). Receiver operating characteristic curve analysis identified an optimal cutoff score of 41 by maximizing the combined sensitivity and specificity for screening significant fatigue, according to Youden's Index.

Conclusions

The post-dialysis fatigue scale is a valid and reliable scale for assessing fatigue in patients undergoing hemodialysis and consists of two factors: behavioral fatigue and sensory fatigue. The translated scale provides a reliable and valid method for assessing dialysis-related fatigue in Vietnamese patients, and the identified cutoff point can facilitate quick screening in clinical settings.

越南血液透析患者透析后疲劳量表的翻译与验证

疲劳是血液透析患者普遍存在的症状，严重影响患者的生活质量。有几种测量疲劳的仪器。然而，这些仪器大多测量一般疲劳，没有特别强调与血液透析有关的疲劳。最近，一种有效的量表，透析后疲劳（PDF）量表，通过直接测量透析后疲劳来解决这一差距。本研究的目的是将英文版PDF量表翻译成越南文，并考虑到疲劳体验中潜在的文化差异，检验其信度和效度。设计采用横断面研究，在两家医院通过方便抽样获得参与者。328名接受血液透析治疗的参与者被招募。采用内容效度、并行效度和构念效度对13项越南版透析后疲劳量表进行效度评价。采用探索性和验证性因素分析来分析量表的潜在结构，并确认数据是否符合假设的测量模型。信度采用Cronbach’s alpha和重测信度进行检验。结果量表具有良好的内容效度指数（CVI: 0.86-1.00）、良好的内部一致性（Cronbach’s alpha为0.90）和可接受的重测信度（类间相关系数为0.84）。探索性因素分析由行为疲劳和感觉疲劳两个因素构成，占方差的59.38%。验证性因子分析显示模型拟合良好（CFI = 0.952, NFI = 0.912, RMSEA = 0.073）。根据约登指数（Youden's Index），受试者工作特征曲线分析通过最大化筛查明显疲劳的敏感性和特异性，确定了41分的最佳临界值。结论透析后疲劳量表是一种有效、可靠的血液透析患者疲劳评估量表，由行为疲劳和感觉疲劳两个因素组成。翻译后的量表为评估越南患者的透析相关疲劳提供了一种可靠而有效的方法，并且确定的截止点可以促进临床环境中的快速筛查。

期刊介绍： The Journal of Renal Care (JORC), formally EDTNA/ERCA Journal, is the official publication of the European Dialysis and Transplant Nursing Association/European Renal Care Association (EDTNA/ERCA). The Journal of Renal Care is an international peer-reviewed journal for the multi-professional health care team caring for people with kidney disease and those who research this specialised area of health care. Kidney disease is a chronic illness with four basic treatments: haemodialysis, peritoneal dialysis conservative management and transplantation, which includes emptive transplantation, living donor & cadavaric transplantation. The continuous world-wide increase of people with chronic kidney disease (CKD) means that research and shared knowledge into the causes and treatment is vital to delay the progression of CKD and to improve treatments and the care given. The Journal of Renal Care is an important journal for all health-care professionals working in this and associated conditions, such as diabetes and cardio-vascular disease amongst others. It covers the trajectory of the disease from the first diagnosis to palliative care and includes acute renal injury. The Journal of Renal Care accepts that kidney disease affects not only the patients but also their families and significant others and provides a forum for both the psycho-social and physiological aspects of the disease.
