El objetivo del presente estudio es realizar un análisis psicométrico de la escala AF5 en una muestra catalana de 4.825 sujetos de 11 a 63 años, estudiantes de ESO, bachillerato, ciclos formativos de grado medio (CFGM) y universitarios. Mediante un análisis de componentes principales (ACP) se constata la validez teórica de los componentes y se analiza la fiabilidad del instrumento. Se realizan análisis diferenciales por género y grupo normativo utilizando un diseño factorial 2x6. La variable grupo normativo incluye diferentes cursos en 6 subgrupos: universitarios, Post-ESO (estudiantes de bachillerato y CFGM), 4º Eso, 3º ESO, 2º ESO y 1º ESO. Los resultados indican que la fiabilidad de la versión catalana de la escala es similar a la de la escala original. También la estructura factorial coincide con la del modelo original establecido a priori. Se observan diferencias significativas por grupo normativo en los cuatro componentes del autoconcepto explorados (social, familiar, académico/laboral y físico). Por razón de género, las diferencias significativas aparecen en los componentes del autoconcepto físico, académico y social pero no en el familiar.

Psychometric analysis of the AF5 multidimensional scale of self-concept in a sample of adolescents and adults in Catalonia. The aim of this study is to carry out a psychometric study of the AF5 scale in a sample of 4.825 Catalan subjects from 11 to 63 years-old. They are students from secondary compulsory education (ESO), from high school, middle-level vocational training (CFGM) and from the university. Using a principal component analysis (PCA) the theoretical validity of the components is established and the reliability of the instrument is also analyzed. Differential analyses are performed by gender and normative group using a 2x6 factorial design. The normative group variable includes the different levels classified into 6 sub-groups: university, post-compulsory secondary education (high school and CFGM), 4th of ESO, 3rd of ESO, 2nd of ESO and 1st of ESO. The results indicate that the reliability of the Catalan version of the scale is similar to the original scale. The factorial structure also fits with the original model established beforehand. Significant differences by normative group in the four components of self-concept explored (social, family, academic/occupational and physical) are observed. By gender, significant differences appear in the component of physical self-concept, academic and social but not in the family component.
