Abstract

Introduction: Hostile and benevolent classism influence the derogation of poor people and groups, with negative consequences. The present study aims to adapt and validate the Ambivalent Classism Inventory (ACI) to obtain an adequate tool for expanding research on this topic among the Spanish-speaking population. Method: Toward this end, the researchers back-translated the ACI version originally developed for English speakers. Exploratory and confirmatory analyses verify the ACI’s reliability and factor structure with a sample of Mexican participants. Results: The results demonstrated that the adapted scale’s psychometric properties are acceptable. Its original and factor structure are similar to those of the original scale: hostile classism (12 items), protective paternalism (4 items), and complementary class differentiation (4 items). Furthermore, the study tests the convergent and divergent validity of the scale´s sub-dimensions concerning other ideological and socioeconomic variables. Conclusion: The proposed ACI adaptation should contribute to understanding attitudes toward the poor as well as their consequences among Spanish speakers.
