Cross-Country Measurement Equivalence of Political Trust in the European Social Survey

Summary/Abstract: One of the main goals of cross-cultural surveys is to compare countries on the basis of values of latent constructs. Such comparisons are only permissible, however, if the measurement process complies with cross-country equivalence. Using the data form the 7th wave of the European Social Survey, this article investigates whether the measurement of political trust is country invariant. The use of configural and metric equivalence tests demonstrate that this construct can be considered reliable and cross-country valid. However, if one applies stricter scalar equivalence test, the measurement of political trust is not fully invariant, and especially the item on trust in the legal system is posing major problems in a number of countries. This article is concluded by testing the concurrent validity of political trust scale and by offering some suggestions on how to compare European countries, even if the measurement of political trust is not fully cross-country invariant.
