Abstract
Financial knowledge has been recognized as an essential element for making informed financial decisions, promoting greater autonomy, security and financial well-being. To allow a valid and reliable measurement of this knowledge, we listed nine questions from instruments developed and validated in the Brazilian context, and used Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) to validate an ultra-short scale, giving rise to an instrument with three items, which we call FK4BR. To assess convergent validity, we used three basic conditions listed in the literature, Composite Reliability (CR), Average Variance Extracted (AVE) and the relationship between the two. The results found demonstrate that the structure proposed for FK4BR presented satisfactory evidence of quality, reliability and convergent validity.
