Abstract
The purpose of the research was to obtain psychometric evidence of a measuring self-concept with the university population of a Colombian city, called EVA-42 and previously developed by the authors based on the Shavelson self-concept model. To do this, a cluster sampling of 500 university students to whom the EVA-42 was applied digitally was carried out. Indicators of goodness of fit were estimated using CFA and correlations between the subscales of the EVA-42 and another instrument for measuring self-concept called AF5; Likewise, reliability coefficients were estimated by internal consistency and scales were established using centiles. The AFC results support a penta-factorial structure with CMIN / DF = 1.758, RMSEA = .039, TLI = .950, CFI = .958 and NFI = .908, as well as Spearman-Brown values and α> .8 for reliability of all subscales. It is concluded that the instrument is adequate for measuring self-concept with the Colombian university population.
