Ambivalent Sexism Inventory (ASI) in Chilean adolescents: Factor structure, reliability, validity and sex invariance

Ambivalent sexism is a multidimensional construct conformed by hostile and benevolent beliefs and attitudes that tend to legitimize each other justifying male structural power. Sexism studies in adolescent population become relevant as it is a fundamental evolutive stage for settle gender relations beliefs. However, the tools that measures sexist representations in adolescents are scarce. The main goal was to evaluate the psychometric properties of the Ambivalent Sexism Inventory (ASI) in Chilean adolescents, and analyze invariance by sex. Sample was composed of 546 students between 15-18 years (M= 15.52; SD=.66), of which 58.8% were women. Exploratory factor analyses and confirmatory factor analyses were the method of the study. The results of the exploratory factor analyses suggested to hold back the 20 items from the original structure grouped in two factors. Confirmatory factor analyses results showed suitability of the two factors theoretical proposal, hostile sexism and benevolent sexism (chi(2)((166))= 302.34; CR = .99; TLI = .98; RMSEA = .05; SRMR = .07). which includes benevolent sexism as a second-order factor conformed by three subcomponents (protective paternalism, complementary gender differentiation, and heterosexual intimacy). The factorial structure of the selected model explained 56% of the total variance. The reliability of the ASI reached a satisfactory levels of ordinal alpha (uordinal = .93) for the complete instrument and the correlation analyses provide evidences of discriminant validity. The Invariance factorial analyses showed that the equivalence level of the ASI is plausible in the strict level. It is concluded that the ASI presents adequate psychometric properties for its use in Chilean adolescent population.
