The purpose of this study was to validate the Gender Ideology Scale (EIG) in the Colombian context. The EIG was administered to 313 adolescents (mean age = 14.62 years old). Confirmatory factor analysis failed to verify the original 12-item one factor model. Tree items were deleted (< 0.3) and confirmatory factor analysis results supported a 9-item one-factor structure for the scale (RMSEA = 0.033, NFI = 0.914, CFI = 0.963). The reliability was α= 0.763. According to the results of the study the EIG has been shown to be a valid tool for measuring gender ideology in adolescents.
