作者阐述了在评估新开发的临床评估措施中递增有效性的概念和方法基础。递增效度被定义为一种衡量标准相对于其他衡量标准解释或预测感兴趣的现象的程度。增量效度可以在几个维度上进行评估，例如对变化的敏感度，诊断效率。内容效度、治疗设计和结果、收敛效度。增量效度指数可以根据标准测量、比较测量和样本中的个体差异而有所不同。作者回顾了增量验证的理论基础、原则和方法，包括比较和标准测量的选择，并讨论了数据分析策略和增量有效性评估在测量选择中的条件性质。递增有效性有助于成本效益，但不同于成本效益。它们反映了获取数据的成本和从数据中获得的好处。增量有效性指数对是否选择测量的影响将受到获取新数据的成本、测量的现象的重要性以及新数据的临床实用性的影响。
The authors address conceptual and methodological foundations of incremental validity in the evaluation of newly developed clinical assessment measures. Incremental validity is defined as the degree to which a measure explains or predicts a phenomenon of interest, relative to other measures. Incremental validity can be evaluated on several dimensions, such as sensitivity to change, diagnostic efficacy. content validity, treatment design and outcome, and convergent validity. Indices of incremental validity can vary depending on the criterion measures, comparison measures, and individual differences in samples. The authors review the rationale for, principles, and methods of incremental validation, including the selection of comparison and criterion measures, and address data analytic strategies and the conditional nature of incremental validity evaluations in the selection of measures. Incremental validity contributes to, but is different from, cost-benefits. which reflect the cost of acquiring the data and the benefits from the data. The impact of an incremental validity index on whether a measure is selected will be moderated by the cost of acquiring the new data, the importance of the measured phenomenon, and the clinical utility of the new data.
