This study examines the relation of dimensions of ethnocentrism with socio-structural factors such as socioeconomic status (SES), feelings of anomie, and authoritarianism. Using clustered sampling, 500 students were selected from ten high schools in Ahvaz, Iran. Results of structural equation modeling showed that SES has a direct positive effect on ethnocentrism and an indirect effect through anomie and authoritarianism. Similarly, anomie mediates the effect of SES on authoritarianism. Anomie was found to have an indirect effect on dimensions of ethnocentrism via authoritarianism. Findings confirmed the proposed conceptual path model, which is consistent with findings from other countries. The influence of feelings of anomie in the model is highlighted since it has a very important effect on dimensions of ethnocentrism.
