Cross-National Measure of Fear-Based Xenophobia: Development of a Cumulative Scale

To apply a Mokken Scale Procedure in developing a hierarchical cross-national scale to measure xenophobia, a pool of 30 xenophobia-related items was collected from several sources and modified using established unidimensional criteria. The survey was administered to 608 undergraduate students in the USA, 193 undergraduate students in The Netherlands, and 303 undergraduate students in Norway. 14 items measuring perceived threat or fear and meeting the criteria of the Stereotype Content Model were selected for further analysis. A separate item analysis and, subsequently, Mokken Scale Procedure yielded a cumulative scale with the same five items for each of the three samples. The items and the total scale met criteria for homogeneity in all samples with H > .40.
