Examining measurement equivalency within the Latin American module of the International Civic Competence Study 2009.

The International Civic and Citizenship Education Study (ICCS) studies are intercontinental studies on the civic education of youth from Asia, Europe, and Latin America. Before we engage in comparative studies on youth from different world regions, we must first establish the equivalency of the scales and items within the databases. The purpose of this study was to examine the level of differential functioning on the Attitudes Towards Neighborhood Diversity 10-item scale in the Latin American module within the ICCS 2009 database for youth from Colombia, Guatemala, and Chile. We first examined the unidimensionality of the scale within each country by assessing configural invariance. Of countries that demonstrated at least adequate fit for configural invariance, we proceeded to examine differential functioning at the item and scale levels. Findings demonstrated that configural invariance held for Chile and Guatemala only. While differential functioning was present on nine of the 10 items between Chile and Guatemala, in all cases the amounts were negligible. There was no differential functioning on the overall scale. Whilst equivalency holds for certain countries on certain scales, in other cases it did not. Thus scholars may consider scale refinement methods before making comparative analyses.
