The performance of both clinical diagnostic and mass screening tests is commonly measured in terms of the two basic parameters, sensitivity and specificity. Selection of cut-off points, balancing the sensitivity-specificity trade-off, and comparison with alternative tests are often a matter of arbitrary decisions and are frequently made without consideration of outcome. Some of the concepts used in the analysis of visual signal detection systems can be helpful in this aspect of screening test selection and evaluation. A simplified version of these concepts is developed and its application to clinical and public health optometry is illustrated.
临床诊断测试和大规模筛查测试的性能通常根据两个基本参数来衡量，即灵敏度和特异性。截止点的选择、平衡灵敏度与特异性之间的权衡以及与其他测试进行比较，往往是主观决定的，而且常常在不考虑结果的情况下做出。视觉信号检测系统分析中使用的一些概念在筛查测试的选择和评估方面可能会有所帮助。本文提出了这些概念的简化版本，并举例说明了其在临床和公共卫生验光中的应用。
