研究目的：健康相关生活质量（HRQoL）是美国公共卫生计划“健康人2010”中提出的一项重要的人群健康监测指标。作者调查了重测信度的四个HRQoL问题，从美国行为危险因素监测系统（BRFSS）。设计：随机抽样的BRFSS的受访者从密苏里州重新接触的HRQoL问题的重测。可靠性估计x统计分类问题和组内相关系数连续questions.Setting：密苏里州美国。参与者：868受访者重新通过电话采访约两个星期后，首次采访（平均13.5天）。参与者代表成年人，非机构化人口的密苏里州：59.1%的妇女，平均年龄49.5岁，93.2%的白色race.Main results：复检可靠性是优秀的（0.75或更高）自我报告的健康和健康的日子措施，和中度（0.58至0.71）的其他措施。老年人的可靠性较低。其他人口统计学亚组（例如，性别）没有表现出不同的可靠性的规律，并有很小的变化可靠性之间的时间间隔的第一次和第二次interview.Conclusions：重测的HRQoL核心的可靠性是中等至优秀。缩放选项将需要未来的关注，因为将研究构成重要的人群差异和HRQoL变化的适当指标。
Study objectives: Health related quality of life (HRQoL) is an important surveillance measure for monitoring the health of populations, as proposed in the American public health plan, Healthy People 2010. The authors investigated the retest reliability of four HRQoL questions from the US Behavioral Risk Factor Surveillance System (BRFSS).Design: Randomly sampled BRFSS respondents from the state of Missouri were re-contacted for a retest of the HRQoL questions. Reliability was estimated by x statistics for categorical questions and intraclass correlation coefficients for continuous questions.Setting: Missouri United States.Participants: 868 respondents were re-interviewed by telephone about two weeks after the initial interview (mean 13.5 days). Participants represented the adult, non-institutionalised population of Missouri: 59.1% women; mean age 49.5 years; 93.2% white race.Main results: Retest reliability was excellent (0.75 or higher) for Self-Reported Health and Healthy Days measures, and moderate (0.58 to 0.71) for other measures. Reliability was lower for older adults. Other demographic subgroups (for example, gender) showed no regular pattern of differing reliability and there was very little change in reliability by the time interval between the first and second interview.Conclusions: Retest reliability of the HRQoL Core is moderate to excellent. Scaling options will require future attention, as will research into appropriate metrics for what constitutes important population group differences and change in HRQoL.
