There is growing recognition that meaningful measures of health-related quality of life must be used to evaluate health care interventions. We examined the practicality and validity of three promising measures of overall health: the General Health Rating Index (GHRI), the Quality of Well-being Scale (QWB), and the Sickness Impact Profile (SIP). Practicality was assessed in terms of interviewer training required, administration time, and respondent burden. Content validity, convergent construct validity, and tests of discriminant validity were also evaluated. Although differing in theory and application, we found that each instrument performed according to the claims of the developers and could provide useful, valid data on overall health. The GHRI may be preferred where brief, self-administered forms are required; the QWB has advantages when health assessments are used to calculate cost-effectiveness; and the SIP is a versatile, easy to understand measure dealing with a wide range of specific dysfunctions. It is worth the required effort to include well-studied measures such as these in any trial intended to provide definitive information on the effectiveness of health care interventions.
人们越来越认识到，必须使用与健康相关的生活质量的有意义指标来评估医疗保健干预措施。我们研究了三种有前景的总体健康指标的实用性和有效性：总体健康评级指数（GHRI）、幸福感量表（QWB）和疾病影响概况量表（SIP）。从所需的访员培训、施测时间和应答者负担方面评估实用性。还评估了内容效度、聚合构想效度和区分效度检验。尽管在理论和应用上有所不同，但我们发现每种工具的表现都符合开发者的声称，并且可以提供有关总体健康的有用、有效的数据。在需要简短的自我施测形式时，GHRI可能是首选；当使用健康评估来计算成本效益时，QWB具有优势；而SIP是一种通用的、易于理解的指标，可处理广泛的特定功能障碍。在任何旨在提供有关医疗保健干预措施有效性的确切信息的试验中，纳入像这样经过充分研究的指标是值得付出所需努力的。
