Testing for Multigroup Invariance Using AMOS Graphics: A Road Less Traveled

Abstract The purpose of this article is to illustrate the steps involved in testing for multigroup invariance using Amos Graphics. Based on analysis of covariance (ANCOV) structures, 2 applications are demonstrated, each of which represents a different set of circumstances. Application 1 focuses on the equivalence of a measuring instrument and tests for its invariance across 3 teacher panels, given baseline models that are identical across groups. Application 2 centers on the equivalence of a postulated theoretical structure across adolescent boys and girls in light of baseline models that are differentially specified across groups. Taken together, these illustrated examples should be of substantial assistance…
