Abstract

An index extending the widely used omega-hierarchical coefficient is discussed, which can be used for evaluating the influence of a second-order factor on the interrelationships among the components of a hierarchical measuring instrument. The index represents a useful and informative complement to the traditional omega-hierarchical measure of explained overall scale score variance by that underlying construct. A point and interval estimation procedure is outlined for the described index, which is based on model reparameterization and is developed within the latent variable modeling framework. The method is readily applicable with popular software and is illustrated with examples.

摘要

本文讨论了一种扩展广泛使用的欧米伽层次系数的指标,该指标可用于评估二阶因子对层次测量工具各组成部分之间相互关系的影响。该指标是对传统欧米伽层次测量的一种有用且信息丰富的补充,传统欧米伽层次测量用于衡量潜在结构对总体量表得分方差的解释程度。本文概述了针对上述指标的点估计和区间估计程序,该程序基于模型重新参数化,并在潜变量建模框架内开发。该方法易于应用于流行软件,并通过实例进行了说明。
