This article reviews methodological issues that arise in the application of exploratory factor analysis (EFA) to scale revision and refinement. The authors begin by discussing how the appropriate use of EFA in scale revision is influenced by both the hierarchical nature of psychological constructs and the motivations underlying the revision. Then they specifically address (a) important issues that arise prior to data collection (e.g., selecting an appropriate sample), (b) technical aspects of factor analysis (e.g., determining the number of factors to retain), and (c) procedures used to evaluate the outcome of the scale revision (e.g., determining whether the new measure functions equivalently for different populations).
本文回顾了在将探索性因素分析（EFA）应用于量表修订和完善过程中出现的方法学问题。作者首先讨论了心理结构的层次性质以及修订背后的动机如何影响EFA在量表修订中的恰当使用。然后他们具体阐述了：（a）数据收集之前出现的重要问题（例如，选择合适的样本）；（b）因素分析的技术方面（例如，确定要保留的因素数量）；以及（c）用于评估量表修订结果的程序（例如，确定新测量方法对不同人群的功能是否等效）。
