目标.虽然广泛使用，并在研究中报告的群体的评价，健康状况和健康相关的生活质量的措施在临床实践中的个别患者的评估应用很少。主要障碍之一是证明这些措施增加了临床上重要的信息，功能或症状的措施单独。本文综述了纵向研究中结构效度的评价方法，并对命名、研究结果的报告和未来的研究方向提出了建议。分析审查。术语“敏感性”和“反应性”可互换使用，很少有研究评价健康状况或健康相关生活质量指标捕获临床重要变化（“反应性”）的程度。目前评价反应能力的方法没有标准化或评价。描述了评估临床显著性或有意义变化的方法;然而，提出了标准化过渡问题，而不是规范性信息。他们将定期报告，并作为单独的轴的描述，以捕捉个人的看法。如果健康状况和与健康相关的生活质量措施要对患者护理产生影响，则评估受试者对测量变化的重要性和幅度的评价的方法研究至关重要。
OBJECTIVES. Although widely used and reported in research for the evaluation of groups, measures of health status and health-related quality of life have had little application in clinical practice for the assessment of individual patients. One of the principal barriers is the demonstration that these measures add clinically significant information to measures of function or symptoms alone. Here, we review the methods for evaluation of construct validity in longitudinal studies and make recommendations for nomenclature, reporting of study results, and future research agenda.METHODS. Analytical review.RESULTS. The terms "sensitivity" and "responsiveness" have been used interchangeably, and there are few studies that evaluate the extent to which health status or health-related quality-of life measures capture clinically important changes ("responsiveness"). Current methods of evaluating responsiveness are not standardized or evaluated. Approaches for the assessment of a clinically significant or meaningful change are described; rather than normative information, however, standardized transition questions are proposed. They would be reported routinely and as separate axes of description to capture individual perceptions.CONCLUSIONS. Research in methods to assess the subject's evaluation of the importance and magnitude of a measured change are critical if health status and health-related quality-of-life measures are to have an impact on patient care.
