Abstract: The focus is on characteristics of some statistical models for measurement invariance analysis based on simulation studies. The measurement invariance sometimes occurs in international surveys, in which scores calibrated by the items do not ensure comparability among groups. Alignment method is a model that provide more practical information than conventional methods based on multi-group analysis. However, invariance index which is provided in the alignment method is not examined its statistical trait well. A purpose is to provide results of the simulation studies as well as real data analysis of international educational assessment data in order to reveal characteristics of some statistical models for measurement invariance analysis developed so far. Further, we propose new index for the measurement invariance analysis.
