Adaptation and validation of the Double Standard Scale in Basque adolescents / Adaptación y validación de la Escala de Doble Estándar en adolescentes vascas-os

Abstract

Abstract The goal was to adapt the Double Standard Scale to the Basque language and to validate it in this language. The sample was comprised of 2,919 adolescents in secondary school. The reliability was analysed and the cross-validation method was applied with exploratory factorial analysis and confirmatory factorial analysis to check the structure of the scale. A differential item analysis was performed according to sex. Finally, correlations were made with ambivalent sexism and distorted beliefs about women and violence, and a contrast of means was performed by sex and age groups using variance analysis and effect sizes. The results were: (a) good internal consistency; (b) a one-dimensional structure with seven items; (c) just one item presents a differential functioning; (d) a positive, significant relationship between the sexual double standard, ambivalent sexism and sexist beliefs; (e) boys and younger adolescents showed a greater adherence to the double standard; and (f) social desirability affects the responses of girls, especially younger ones.
