A variety of methods for computing factor scores can be found in the psychological literature. These methods grew out of a historic debate regarding the indeterminate nature of the common factor model. Unfortunately, most researchers are unaware of the indeterminacy issue and the problems associated with a number of the factor scoring procedures. This article reviews the history and nature of factor score indeterminacy. Novel computer programs for assessing the degree of indeterminacy in a given analysis, as well as for computing and evaluating different types of factor scores, are then presented and demonstrated using data from the Wechsler Intelligence Scale for Children-Third Edition. It is argued that factor score indeterminacy should be routinely assessed and reported as part of any exploratory factor analysis and that factor scores should be thoroughly evaluated before they are reported or used in subsequent statistical analyses.
心理学期刊文献中可以找到多种计算因子得分的方法。这些方法源于一场关于公共因子模型不确定性本质的历史性辩论。遗憾的是，大多数研究者并未意识到不确定性问题以及许多因子计分程序所带来的问题。本文回顾了因子得分不确定性的历史与本质，并使用韦氏儿童智力量表第三版的数据展示并演示了用于评估给定分析中不确定性程度的新型计算机程序，以及用于计算和评估不同类型因子得分的程序。本文认为，因子得分不确定性应作为任何探索性因子分析的一部分进行常规评估和报告，并且在报告因子得分或将其用于后续统计分析之前，应对其进行全面评估。
