Testing for multigroup invariance using AMOS graphics: A road less traveled

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 I 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 to researchers interested in testing for multigroup invariance, using the Amos program.
