In this article, the authors describe how multiple indicators multiple cause (MIMIC) models for studying uniform and nonuniform differential item functioning (DIF) can be conceptualized as mediation and moderated mediation models. Conceptualizing DIF within the context of a moderated mediation model helps to understand DIF as the effect of some variable on measurements that is not accounted for by the latent variable of interest. In addition, useful concepts and ideas from the mediation and moderation literature can be applied to DIF analysis: (a) improving the understanding of uniform and nonuniform DIF as direct effects and interactions, (b) understanding the implication of indirect effects in DIF analysis, (c) clarifying the interpretation of the “uniform DIF parameter” in the presence of nonuniform DIF, and (d) probing interactions and using the concept of “conditional effects” to better understand the patterns of DIF across the range of the latent variable.

统一和非统一DIF的MIMIC模型作为仲裁中介模型。
在本文中,作者描述了如何将用于研究统一和非统一的差异项功能(DIF)的多指标多原因(MIMIC)模型概念化为调解模型和调解模型。在调解模型的上下文中将DIF概念化有助于将DIF理解为某些变量对测量的影响,而这些变量并未受到关注的潜在变量的影响。此外,可以将中介和仲裁文献中的有用概念和思想应用于DIF分析:(a)增进对统一和非均匀DIF作为直接效应和相互作用的理解,(b)理解DIF分析中间接效应的含义, (c)澄清在存在非均匀DIF的情况下对“均匀DIF参数”的解释,
