This paper describes the process by which the Chinese Dialysis Quality of Life Scale was developed, and the preliminary testing and psychometric evaluation of the scale in a sample of dialysis patients.
Quality of life as a specific outcome variable has not been systematically and satisfactorily studied in Chinese dialysis patients in Hong Kong. A single global quality of life measure that is both reliable and valid for dialysis patients has yet to be developed. Without measurement tools, it is impossible to judge progress towards this goal.
A list of key issues was first derived from an in-depth literature review, then verified by semi-structured interview on seven patients. The initial list of 87 items was then further refined through two rounds of content analysis. The remaining 50 items were finalized by pilot test on seven patients. Of the refined 40 items, face validity was assessed by a team including one professor and ten patients. The 40-item scale was further evaluated by stability, internal consistency and criterion validity with a convenience sample of 164 patients. The scale demonstrated high internal consistency and good test-retest reliability and criterion validity when used.
The psychometric evaluations suggest that the instrument is worthy of further development. Continued validation of this scale on larger sample and Chinese population living outside Hong Kong has the potential to provide nurses with a valid assessment and treatment guide, and researchers with a valid measurement tool.
本文描述了中国血液透析生活质量量表的开发过程，以及该量表在一组透析患者样本中的初步测试和心理测量评估。
生活质量作为一个特定的结果变量，在香港的中国透析患者中尚未得到系统和令人满意的研究。尚未开发出一种对透析患者既可靠又有效的单一整体生活质量测量方法。没有测量工具，就无法判断朝着这个目标取得的进展。
首先通过深入的文献综述得出一系列关键问题，然后通过对7名患者进行半结构化访谈进行验证。然后通过两轮内容分析对最初的87个项目列表进行进一步完善。其余50个项目通过对7名患者的预试验确定。在经过完善的40个项目中，由一名教授和十名患者组成的团队评估表面效度。使用便利抽样的164名患者对该40项量表进一步进行稳定性、内部一致性和效标效度评估。该量表在使用时表现出高内部一致性、良好的重测信度和效标效度。
心理测量评估表明该工具值得进一步开发。在更大样本和香港以外的中国人群中继续验证该量表，有可能为护士提供有效的评估和治疗指南，并为研究人员提供有效的测量工具。
