在自然观察性研究、临床试验和临床实践中，与健康相关的生活质量评估正在加速。一些研究人员认为，随着时间的推移，生活质量仪器检测临床重要变化的能力，即“反应性”，与测量的可靠性和有效性不同，是一种独特的心理测量特性。我们讨论了这一论点的重要含义，并反驳说，响应性实际上是衡量有效性的一个指标。
Assessment of health-related quality of life is accelerating in naturalistic observational studies, clinical trials, and clinical practice. Some researchers have argued that the ability of a quality of life instrument to detect clinically important changes over time, "responsiveness," is a distinct psychometric property from the measure's reliability and validity. We discuss the important implications of this argument and counter that responsiveness is actually one indication of a measure's validity.
