Some Methods for Respecifying Measurement Models to Obtain Unidimensional Construct Measurement
回顾了构念单维测量的必要条件，介绍了多重分组分析和相似系数两种方法帮助研究者重新指定测量模型，并给出应用示例。
Lack of unidimensionality in structural equation models most often represents misspecification. The authors review the necessary conditions for unidimensional measurement of constructs. Two methods which assist the researcher in measurement model respecification, multiple-groups analysis and similarity coefficients, are presented and an example illustrating the use of these methods is given.
