背景资料：在最新发布的《教育与心理测验标准》中，项目功能差异（DIF）被认为是基于内部结构的效度证据。然而，没有迹象表明如何设计DIF研究作为验证研究。在本文中，我们建议DIF的有效性证据的所有来源，并提供了一个一般的概念框架转换为验证研究的“典型”DIF研究。方法：我们进行了全面的文献综述，并提出理论和实践建议。结果如下：本文提供了支持将DIF检测和解释作为验证研究的论据，以及进行DIF验证研究的建议。讨论内容：结合定量和定性数据的混合方法研究的角度来看，沿着规划DIF研究作为验证研究，可以帮助提高考试成绩解释的有效性。
Background: In the latest release of the Standards for Educational and Psychological Testing, Differential Item Functioning (DIF) is considered as validity evidence based on internal structure. However, there are no indications of how to design a DIF study as a validation study. In this paper, we propose relating DIF to all sources of validity evidence, and provide a general conceptual framework for transforming "typical" DIF studies into validation studies. Method: We perform a comprehensive review of the literature and make theoretical and practical proposals. Results: The article provides arguments in favour of addressing DIF detection and interpretation as validation studies, and suggestions for conducting DIF validation studies. Discussion: The combination of quantitative and qualitative data within a mixed methods research perspective, along with planning DIF studies as validation studies, can help improve the validity of test score interpretations.
