Objetivo: El objetivo de este trabajo es presentar el estudio inicial de las propiedades psicométricas de la escala de autoestima Autoe en población general de la Ciudad de Buenos Aires. Muestra: La muestra se conformó por 171 personas adultas, 86 hombres y 85 mujeres. Instrumento: La escala Autoe está basada en la escala de autoestima global de Rosenberg, consta de 10 ítems. Resultados: Se realizó un análisis de discriminación de los ítems. Los ítems 1 y 10 se eliminaron por poseer inadecuado poder discriminativo. Posteriormente, se efectuó un análisis factorial exploratorio de componentes principales con criterio Kaiser y rotación varimax. Se extrajeron dos factores que explicaban el 45.1% de la varianza. El primer factor contenía a los ítems positivos y el segundo a los negativos, 26% y 19.1% de varianza explicada respectivamente. Los coeficientes alphas resultaron relativamente adecuados considerando la baja cantidad de ítems: total, (a =.62), factor 1 (a =.61) y factor 2 (a =.46). Finalmente la escala mostró que no había diferencias significativas en las puntuaciones entre hombres y mujeres. Discusión: La escala resultó tener una adecuada estructura factorial comparable a estudios previos internacionales pero dos ítems de la escala original tuvieron que ser eliminados. Palabras clave Autoestima Evaluación Validación Adultos ABSTRACT VALIDATION OF THE SELF-ESTEEM SCALE AUTOE IN GENERAL POPULATION OF BUENOS AIRES Aim: The aim of this study is to present the preliminary psychometric properties of the self-esteem scale Autoe in general population of Buenos Aires. Sample: The sample was composed of 171 adult persons, 86 men and 85 women. Instrument: The Autoe scale is based on the Rosenberg global selfesteem scale and it comprises 10 items. Results: A discriminant analyses of items was first performed. Items 1 and 10 were removed due to their low discriminate power. A principal component factor analysis with varimax rotation was later executed. Two factors were extracted which explained the 45.1% of the total variance. The first factor contained the positive items while the second factor included the negative ones, 26% and 19.1% of explained variance, respectively. Alphas coefficients were relatively adequate considering the low number of items: total, (a =.62), factor 1 (a =.61) and factor 2 (a =.46). Finally the scale indicated that there were no significant differences between the scores of men and women. Discussion: The scale shows an adequate factorial structure similar to international previous studies but two items of the original scale had to be removed.
