Norms and Performance Comparisons for 5 Health indexes

描述（由申请人提供）：我们提出一个项目计划，以推进评估美国老年人健康相关生活质量（HRQOL）的应用科学。我们同时使用四种广泛使用的通用HRQOL仪器，SF-36v2, EuroQol EQ-5D，幸福质量量表（QWB-SA）和健康效用指数（HUI2/3）。此外，我们使用国家卫生统计中心的HALex。项目一采用电话调查的方式对2800名年龄在35-89岁之间的非收容成年美国居民进行横断面抽样调查。65岁及以上的人将被过度抽样，以提供更高的老年精度。非洲裔美国人在这一重要亚群的第一次全国大规模调查中被过度抽样（n=1000）。项目1的数据将用于构建老年人HRQOL所有指标的性别和年龄特定的国家参考平均值。项目2将使用所有四种方法跟踪患有三种年龄相关疾病的患者的治疗和6个月的恢复情况，这些疾病对HRQOL的不同方面造成了影响，新转诊的充血性心力衰竭、骨关节炎髋关节置换术和白内障摘除。本项目将建立自填问卷对患者进行纵向随访的措施特点。项目3研究健康状况的持续时间如何影响HRQOL评估，以及这如何影响根据标准化指数对HRQOL评分的解释。这对老年人尤其重要，因为医疗保健日益延长慢性病患者的生命。项目4确定了所有工具的调查模式效果（电话与自我管理），以及通常说西班牙语的人的英语与西班牙语管理。该项目将提高健康研究人员测量、跟踪和解释成人HRQOL的能力，并评估健康差异。

DESCRIPTION (provided by applicant): We propose a Program of Projects to advance the applied science of evaluating health-related quality of life (HRQOL) in older U.S. adults. We simultaneously use four widely-used generic HRQOL instruments, the SF-36v2, EuroQol EQ-5D, Quality of Well-being scale (QWB-SA), and Health Utilities Index (HUI2/3). Additionally we use the HALex from the National Center for Health Statistics. Project 1 uses a telephone survey to interview a cross-sectional sample of 2800 non-institutionalized adult U.S. residents aged 35-89. Persons aged 65 and older will be over-sampled to provide higher precision in older ages. African Americans are over-sampled for the first national survey of substantial size (n=1000) of this important sub-population. Project 1 data will be used to construct gender- and age-specific national reference averages for HRQOL among older adults on all measures. Project 2 will use all four measures to follow treatment and 6 month recovery of patients with three age-related diseases stressing different aspects of HRQOL newly referred congestive heart failure, hip replacement for osteoarthritis, and cataract extraction. This project will establish characteristics of the measures for longitudinal follow-up of patients with self-administered questionnaires. Project 3 examines how duration of a health condition affects HRQOL assessments and how this affects interpretation of HRQOL scores from standardized indexes. This is particularly important in the elderly as medical care increasingly prolongs life with chronic conditions. Project 4 determines survey mode effects (telephone versus self-administration) for all instruments as well as English versus Spanish language administration for persons who are usually Spanish speakers. The Program will enhance health researchers' ability to measure, follow, and interpret HRQOL in adults and to assess health disparities.
