There has been insufficient effort in most areas of applied psychology to evaluate incremental validity. To further this kind of validity research, the authors examined applicable research designs, including those to assess the incremental validity of test instruments, of test-informed clinical inferences, and of newly developed measures. The authors also considered key statistical and measurement issues that can influence incremental validity findings, including the entry order of predictor variables, how to interpret the size of a validity increment, and possible artifactual effects in the criteria selected for incremental validity research. The authors concluded by suggesting steps for building a cumulative research base concerning incremental validity and by describing challenges associated with applying nomothetic research findings to individual clinical cases.
在应用心理学的大多数领域，评估增量效度的工作都做得不够。为了推动这类效度研究，作者们考察了适用的研究设计，包括评估测试工具、基于测试信息的临床推断以及新开发测量方法的增量效度的研究设计。作者们还考虑了可能影响增量效度研究结果的关键统计和测量问题，包括预测变量的进入顺序、如何解释效度增量的大小，以及在为增量效度研究选择的标准中可能存在的人为效应。作者们最后提出了建立关于增量效度的累积研究基础的步骤，并描述了将一般研究结果应用于个体临床案例所面临的挑战。
