本文所依据的研究目的是评估一种旨在衡量生活质量的工具的有效性和可靠性。对研究生（n= 88）进行了适用于健康受试者和透析患者的64个项目的测试;增加了6个与透析相关的项目，并将该仪器用于透析患者（n= 37）。题目基于文献综述，支持内容效度。该工具和整体满意度与生活问题的相关性为0.75（研究生）和0.65（透析患者），支持标准相关效度。支持可靠性的重测相关系数为0.87（研究生）和0.81（透析患者），Cronbach α为0.93（研究生）和0.90（透析患者）。
The purpose of the study on which this article is based was to assess the validity and reliability of an instrument designed to measure quality of life. Sixty-four items applicable to both healthy subjects and dialysis patients were tested with graduate students (n= 88); six items relative to dialysis were added, and the instrument was administered to dialysis patients (n= 37). Items were based on literature review, which supported content validity. Correlations between the instrument and an overall satisfaction with life question of 0.75 (graduate students) and 0.65 (dialysis patients) supported criterion-related validity. Support for reliability was provided by test-retest correlations of 0.87 (graduate students) and 0.81 (dialysis patients) and Cronbach's alphas of 0.93 (graduate students) and 0.90 (dialysis patients).
