This paper presents the design, construction and validation of a literacy measurement scale from the imbrication of complex thinking with the literacies of financial knowledge, behavior and attitude. Content validity was analyzed from the judgment of 13 experts through the application of the Simplified Digital Delphi method and a reliability study was carried out considering 112 university students. The results show a solid internal consistency because the items obtained a Cronbach's alpha greater than 0.8, as well as positive correlations between the dimensions that comprise it. Therefore, it is a valid and reliable instrument that allows the verification of financial knowledge, behaviors, and attitudes. It is suggested that future studies could incorporate variables related to the use of digital financial applications.TextoengopenAccesshttp://creativecommons.org/licenses/by/4.0HUMANIDADES Y CIENCIAS DE LA CONDUCTA::PEDAGOGÍA::TEORÍA Y MÉTODOS EDUCATIVOSEducationArtículoMultidisciplinary Journal of Educational Researchhttps://orcid.org/0000-0002-2529-9155https://orcid.org/0000-0002-1274-706Xhttps://orcid.org/0000-0003-0919-8108https://orcid.org/0000-0002-1216-4219financial literacyhigher educationeducational innovationDelphi methodcomplex thinkingR4C&TE124España / Spain
