To form a scale of ethnocentrism, 32 items were selected according to both their power of discrimination between criterion groups of subjects and their internal consistency in a pilot study of 192 subjects. The original pool of items was set up to comply with various facets of ethnocentrism as defined by Levinson and illustrated in the California E scale and the British Ethnocentrism scale. Validity was demonstrated in the main study of 273 subjects by highly significant differences between criterion groups selected according to age, socio-economic status, student-nonstudent, levels of education, income, religion and other criteria in accord with the theory and previous findings in Britain and the U.S. Partitioning of the main sample revealed the predominance of education as a determinant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
