Approaches to equivalence in cross-cultural and cross-national survey research

"In cross-cultural (and cross-national) survey research, the equivalence of survey questions rivals the importance of their reliability and validity. This paper presents a review of the multiple dimensions of equivalence that must be addressed when conducting comparative survey research. Available methodologies for establishing one or more forms of equivalence are also identified and the strengths and limitations of each approach are examined. It is concluded that multiple methodologies must be implemented in order to insure the cross-cultural equivalence of survey measures." (author's abstract)
