Analysis of the psychometric properties of the Piers-Harris Self-Concept Scale 2 in Mexican school children

Abstract

Currently, in Mexico there are few valid instru-ments to evaluate self-concept in children, so the objective of this work was to analyze the psychometric properties of the adaptation of the Piers-Harris Self-Concept Scale 2 in 493 school children from 7 to 12 years of age (female 50.5%), with an average fourth grade school level. The study was transversal quantitative with a non-experimental analytical empirical approach. Internal consistency was evaluated using the KR20 formula, with results similar to other studies (index. 0.87). Rasch mode-led analysis indicates that 58 reagents on the scale obtained good validity, reliability, and fit properties. This scale has adequate psychometric properties for its use in Mexican schoolchildren from 7 to 12 years old.
