Using Indices of Group Agreement in Multilevel Construct Validation
阐述了群体一致性指标在多层次构念验证中的作用，通过两步流程（多特质多方法验证性因子分析和离散模型）检验构念共识的相关因素，并利用三个效能相关构念示例说明离散模型如何提供区分效度证据及解释团队感知差异的原因。
This article illustrates the role of group-agreement indices in the process of multilevel construct validation. A two-step process is outlined that includes multitrait-multimethod confirmatory factor analysis (CFA) and the use of a dispersion model to examine correlates of consensus of multilevel constructs. The role of dispersion models for providing discriminant validity evidence for similar constructs, as well as providing insight as to why some teams share perceptions more strongly than others, is illustrated using three efficacy-related constructs.
