CEBALLOS-OSPINO, Guillermo Augusto et al. Validity and Dimensionality of the Rosenberg Self-esteem Scale Among College Students. Pensam. psicol. [online]. 2017, vol.15, n.2, pp.29-39. ISSN 1657-8961.  https://doi.org/10.11144/Javerianacali.PPSI15-2.vdea.

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 coefficient 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 coefficient, 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.
