| In comparative social research, one of the most important
issues is the validity of the comparison among the comparative categories.
More specifically, one has to make sure that the attitude, attribute, etc.
of interest is measured invariantly across these categories. Several statistical
techniques exist to assess the measurement invariance of Likert score items.
This presentation provides an overview of such techniques, discusses their
appropriateness and provides guidelines for the assessment of measurement
invariance of Likert score items in substantive research.
