Abstract

Currently, in Mexico there are few valid instruments 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 schoolchildren 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 modeled 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.
