MENDEZ VERA, Juan  y  GALVEZ NIETO, José Luis. Psychometric properties of the Academic Self-Concept Scale in Chilean university students. liber. [online]. 2018, vol.24, n.1, pp.131-145. ISSN 1729-4827.  http://dx.doi.org/https://doi.org/10.24265/liberabit.2018.v24n1.09.

The current study aimed to evaluate the psychometric properties of the Academic Self-Concept Scale in a sample of university students from Chile. To that end, a cross-sectional study was conducted and participants were selected through a probabilistic hierarchical method, resulting in a sample size of 1290 students of both genders (57% females and 43% males) with a mean age of 21.03 years. The structure of the scale was checked through an exploratory and confirmatory factor analysis using the cross-sample method. The analysis of the scale showed suitable psychometric properties to be used in university students, while maintaining its two-factor structure that explain 53.7% of the construct´s variance. Cronbach’s Alpha and McDonald’s Omega regarding the Perceived Performance subscale were α = .753 and ω = .787, and regarding the Academic Self-Efficacy subscale were α = .802 and ω = .867. The results enable us to conclude that the Academic Self-Concept Scale is a valid and reliable instrument to assess academic self-concept in university students.
