摘要：Objetivo. Conocer la consistencia interna y la dimensionalidad de la escala de Rosenberg para evaluar la autoestima (ERA) en universitarios de Santa Marta, Colombia. Método. Se seleccionó una muestra de 1341 estudiantes, entre 18 y 30 años, de varios programas académicos, que diligenciaron la ERA. Los coe fi cientes alfa de Cronbach y omega de McDonald se calcularon para la con fi abilidad, el coe fi ciente de Mosier, para medir unidimensionalidad, y los análisis factoriales exploratorios, para medir la dimensionalidad de la ERA. Resultados. En la escala se observó un alfa de Cronbach de 0.72, un omega de McDonald de 0.65 y un coe fi ciente de Mosier de 0.75. La ERA mostró dos dimensiones: (a) autoestima positiva, que explicó el 32.3% de la varianza, y (b) autoestima negativa, responsable del 13.8% de la varianza. Estas dimensiones presentaron baja correlación entre ellas. Conclusión. La ERA cuenta con dos dimensiones, autoestima positiva y autoestima negativa, que se comportan como escalas distintas.
其他摘要：Objective. The objective of the research was to determine the internal consistency and dimensionality of the Rosenberg self-esteem scale (RSES) in college students from Santa Marta, Colombia. Method. A sample of 1.341 students was used in the application of the RSES. Students were aged between 18 and 30 years, mean = 20.6 years (SD = 3.4); 50.7% were males. Cronbach alpha and McDonald omega were computed to estimate reliability. Mosier’s coef fi cient was calculated to measure the dimensionality. Exploratory factor analyses were conducted to observe the dimensionality of the RSES. Results. Cronbach alpha for RSES was 0.72; McDonald omega, 0.65; and Mosier coef fi cient, 0.75. The RSES showed two dimensions, ‘positive self- esteem’ that explained 32.3% of the variance; and ‘negative self-esteem’ which accounted for 13.8% of the variance. These dimensions showed a low correlation each other. Conclusion. The RSES is a scale with two dimensions, ‘positive self-esteem’ and ‘negative self-esteem’ which should be considered as separate scales.
