Psychometric Validation of the Information Area of Digital Competence in High School Students in Perú

Abstract

Background/purpose -Few psychometric tests have been identified in the literature that analyze digital competencies in school-aged children. The Evaluation Test of Digital Competencies in Compulsory Education Students (ECODIES, Casillas-Martín et al., 2020) is considered one of the most robust for its measurement. The aim of the study was to assess the psychometric validity of the "ECODIES -Area 1: Information" test with high school students from two Peruvian cities in 2021.Materials/methods -The research was formed as a basic level, nonexperimental, and cross-sectional study. Content validity was analyzed through expert judges (n = 8), while construct validity, factorial invariance, and reliability were tested with a sample of high school students from Lima and Cusco (N = 201).Results -The content validity obtained satisfactory results (Aiken's V = 0.952, p < .01). Through construct validity, it was corroborated that the instrument measures the information competence (RMSEA = 0.052, CFI = 0.948, TLI = 0.928, PNFI = 0.67) and that this theoretical construct remains invariant between both of the groups studied. The instrument also demonstrates adequate internal consistency (α = 0.736, ω = 0.751, ordinal α = 0.869).Conclusion -"ECODIES -Area 1: Information" is a valid and reliable instrument for the assessment of the information digital competence, including cultural differences, in high school students.
