English title: No Two Ageisms Are the Same: Testing Measurement Invariance in Ageism Experience across Europe

Type: Journal article
The article focuses on the topic of measurement invariance (equivalence) testing in comparative research. Measurement invariance is the basic requirement for comparative data and should be addressed by researchers before any international comparison begins. In the article, multiple-group confirmatory factor analysis is first performed to describe three methods of measurement invariance testing (configural, metric and scalar). Subsequently, this procedure is applied to the case of measuring experience with ageism against seniors in the quantitative European Social Survey, Round 4. Measurement invariance in the concept is tested across 29 states participating in the survey. Hypotheses about the sources of the lack of measurement invariance between some countries are then tested by comparing the parameters of the models identified for different groups of European states. Finally, evidence of international comparability of items measuring experience with ageism against seniors is summarized and implications for other areas of comparative social research are discussed.
