Contextual variance and invariance in self

Evidence of cultural comparisons of gender-identity-measurement scales is scarce. The present study aims to assess the scalar invariance of two dimensions of a widely used gender identity scale (Egan and Perry’s Multidimensional Gender Identity Inventory) across two cultural contexts. Fourth, sixth, and fifth graders from Barranquilla (Colombia) and Montréal (Canada) (n = 351) completed an abbreviated, self-report revised version of Egan and Perry’s scale. A Confirmatory Factor Analysis demonstrated that typicality and pressure to conform to traditional gender roles are distinct factors and tend to be stable over time. Furthermore, a multi-group comparison analysis showed that the measurement model did not vary significantly as a function of cultural context. Our study adds evidence to support the use of a reliable and valid measurement instrument that is invariant across cultural settings, to allow comparisons that do not depend on contextual variations in the assessment of gender identity during childhood
