This study aimed to adapt and collect evidence of validity for the factor structure of the Specific Risk-Taking Scale – Evolutionary Domains to Brazilians. Participants were 1244 people answering EPRE-DE and an online sociodemographic questionnaire. The exploratory and confirmatory analysis supported the bidimensional model (cohesion and competition) for the EPRE-DE, with satisfactory reability indexes for research purposes. MANOVA analysis indicated validity by contrasting groups of the measure as men presented higher risk-taking in both dimensions, as predicted by the literature. We concluded the EPRE-DE is a psychometrically adequate instrument best represented by a bidimensional model that allows the differentiation of groups in the assessed constructs.

Palabras clave : risk; psychological measure; evolutionary psychology.
