Los resultados mostraron mejores bondades de ajuste para el modelo unidimensional con control del efecto del método en ítems inversos eliminando el ítem 8 por su ambigüedad. Se identificaron seis modelos mediante análisis factorial confirmatorio, los cuales corresponden a estructuras factoriales reportadas en estudios previos. La escala fue administrada a un total de 715 adolescentes (51.3% de sexo femenino M edad = 12.20 años). La presente investigación tuvo como objetivo principal analizar la estructura interna y la fiabilidad de la RSE en adolescentes peruanos. The unifactorial structure of the RSE is discussed and it is concluded that the instrument reports evidence of validity and adequate internal consistency to be used in the Peruvian context.Keywords: Self-esteem teenagers validity reliability.Resumen: La Escala de Autoestima de Rosenberg (RSE) es un instrumento ampliamente utilizado que fue diseñado para medir la autoestima en una sola dimensión. Reliability was adequate and was calculated using the omega coefficient. The results showed a better goodness of fit for the one-dimensional model with control of method effects on inverse items, eliminating item 8 due to its ambiguity. Six models were identified by confirmatory factor analysis, which correspond to factorial structures reported in previous studies. The scale was administered to a total of 715 adolescents (51.3% female) with an average age of 12.20 years. The aim of this research was to analyze the internal structure and the reliability of the RSE in Peruvian adolescents. Based on the results of the study, RSE has empirical evidence of validity, reliability and non-invariant operation of some items.įactorial models of Rosenberg’s Self-esteem Scale in Peruvian adolescentsAbstract: The Rosenberg Self-Esteem Scale (RSE) is an instrument widely used and designed to measure self-esteem in a single dimension. The results indicate that the RAS should be interpreted according to a two-dimensional model, with a strong partial invariance, and items 1, 5 and 10 should be released, suggesting that item 8 be removed.
On the other hand, differential functioning was estimated through factor invariance. Internal consistency analysis was performed, which for all models was good (H>. The internal structure was evaluated by exploratory and confirmatory factor analysis. An instrumental study was developed in two samples, the first one consisting of 450 (226 women and 224 males) and the second one by 481 (225 females and 256 males) Peruvian adolescents belonging to public and private educational institutions of Metropolitan Lima. ABSTRACT The objective of the research was to analyze the internal structure of the Rosenberg Self-Esteem Scale (RSE) and to verify the differential functioning of the items according to sex. En base a los resultados del estudio, la EAR cuenta con evidencia empírica de validez, confiabilidad y funcionamiento no invariante de algunos ítems. Los resultados indican que la EAR debe ser interpretada de acuerdo a un modelo bidimensional, encontrándose a su vez invarianza fuerte parcial, debiendo liberarse los ítems 1, 5 y 10, sugiriendo retirar el ítem 8. Por otro lado, se estimó el funcionamiento diferencial a través de la invarianza factorial. Se evaluó la estructura interna mediante el análisis factorial confirmatorio, asimismo, se efectuó el análisis de consistencia interna, que para todos los modelos fue bueno (H>.
Se desarrolló un estudio instrumental en dos muestras, la primera conformada por 450 (226 mujeres y 224 varones) y la segunda por 481 (225 mujeres y 256 varones) adolescentes peruanos pertenecientes a instituciones educativas públicas y privadas de Lima Metropolitana. RESUMEN La investigación tuvo como objetivos analizar la estructura interna de la Escala de Autoestima de Rosenberg (EAR) y comprobar el funcionamiento diferencial de los ítems de acuerdo al sexo.
