Data from 655 early adolescents from three contexts (Curitiba, Brazil; Montreal, Canada and Barranquilla, Colombia) were used to test for measurement invariance in the constructs of essentialism and narrativism. These two different strategies have been proposed to explain the perceptions of stability of self-continuity over time. Essentialism predicates self-continuity on some fundamental, unchanging aspect of the self. In contrast, narrativism is an understanding of self-continuity as a result of one’s cumulative experiences and decisions. Previous research using interview methods have found that these two strategies are mutually exclusive expressions of self-continuity. The current study sought to test this conceptualization using a questionnaire that assessed the underlying structural relation between essentialism and narrativism. The analyses supported a two factor model with measurement invariance across samples allowing for a comparison of mean differences across language and cultural barriers. As a whole, these findings highlight the need to examine developmental changes in warranting strategies for self-continuity.
