In cross-cultural comparative studies it is essential to establish equivalent measurement of relevant constructs across cultures. If this equivalence is not confirmed it is difficult if not impossible to make meaningful comparison of results across countries. This work presents concept of measurement equivalence, its relationship with other related concepts, different equivalence levels and causes of inequivalence in cross-cultural research. It also reviews three main approaches to the analysis of measurement equivalence - multigroup confirmatory factor analysis, differential item functioning, and multigroup latent class analysis - with special emphasis on their similarities and differences, as well as comparative advantages.
