A sample of 364 Mexican-American college students were used to study the adequacy of Keefe and Padilla's model and measure of cultural change. Keefe and Padilla developed an empirical measure yielding two divergent factors, labeled as Cultural Awareness and Ethnic Loyalty. An additional factor, labeled Ethnic Social Orientation, referred to preference for ethnicity of associates and types of foods. Results of a confirmatory factor analysis suggest that the process of cultural change among Mexican American college students may be described in terms of Cultural Awareness and Ethnic Loyalty. Consistent with Keefe and Padilla's model, the present study defines Cultural Awareness by scales related to the knowledge and practice of cultural traits, and Ethnic Loyalty by the individual's preference for one cultural orientation over the other. Differences in these three dimensions across students of various generations suggested that Cultural Awareness is somewhat independent of both Ethnic Loyalty and Ethnic Social Orientation. Cultural Awareness seems to decrease the most from the first to the fourth generation while Ethnic Loyalty remains relatively stable from the second to the fourth generation. Similarities in results between Keefe and Padilla's study and the present study, despite differences in samples, suggest that the model of cultural change is valid for Mexican Americans across the spectrum of generational status, language preference, and educational levels.
