探索性和验证性因素分析的目标进行了描述，并为每种方法的程序指南进行了总结，强调使用因素分析在开发和完善临床措施。对于探索性因子分析，根据研究目标是否涉及识别潜在结构或数据减少，提出了主成分分析和公共因子分析之间的选择的理由。描述了使用结构方程模型的验证因子分析用于验证测量的维度结构。此外，使用验证性因素分析评估跨样本的措施的不变性和评估多特征多方法的数据也简要介绍。对项目级数据常见问题的处理提出了建议。并举例说明了从初步探索性分析中确认维度结构的潜在困难。
The goals of both exploratory and confirmatory Factor analysis are described and procedural guidelines for each approach are summarized, emphasizing the use of factor analysis in developing and refining clinical measures. For exploratory factor analysis, a rationale is presented for selecting between principal components analysis and common factor analysis depending on whether the research goal involves either identification of latent constructs or data reduction. Confirmatory factor analysis using structural equation modeling is described for use in validating the dimensional structure of a measure. Additionally, the uses of confirmatory factor analysis for assessing the invariance of measures across samples and for evaluating multitrait-multimethod data are also briefly described. Suggestions are offered For handling common problems with item-level data. and examples illustrating potential difficulties with confirming dimensional structures from initial exploratory analyses are reviewed.
