Summary: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. Actualmente, en México existe escasez de instrumentos válidos para evaluar el autoconcepto en niños, por ello el objetivo del presente trabajo fue analizar las propiedades psicométricas de la adaptación de la Escala de Autoconcepto de Piers-Harris 2 en 493 escolares de 7 a 12 años (mujeres 50.5%), con un promedio de nivel escolar de cuarto grado. El estudio fue transversal cuantitativo con enfoque empírico analítico no experimental. Se evaluó la consistencia interna empleando la fórmula KR20, obteniendo resultados semejantes a otros estudios (índice = 0.87). El análisis con modelamiento Rasch, indica que 58 reactivos de la escala obtuvieron buenas propiedades de validez, confiabilidad y ajuste. Dicha escala presenta propiedades psicométricas adecuadas para ser utilizada en niños escolarizados de 7 a 12 años de población mexicana.
