The measurement properties of a health status indicator are closely related to the scaling model on which it is based. The Thurstone and Bradley-Terry models are applied to paired comparisons data which had been used to scale the sleep category of the Nottingham Health Profile. The data in their original form are shown to be inadequately represented by either model. Weaknesses in the data are identified and the two scaling models are applied to the amended data. The results of applying two sets of scale values are compared.
健康状况指标的测量属性与其所基于的量表模型密切相关。瑟斯顿模型和布拉德利 - 特里模型被应用于成对比较数据，这些数据曾用于对诺丁汉健康概况的睡眠类别进行量表编制。结果表明，这两种模型均无法充分呈现原始形式的数据。研究识别出数据中的弱点，并将这两种量表模型应用于修正后的数据。同时，对应用两组量表值的结果进行了比较。
