Factor Structure and Psychometric Properties of " Self-Esteem Rating Scale" (SERS)

The aim of this research was to explore of the factor structure and psychometric properties of “Self-Esteem Rating Scale” (SERS). To this aim, after performing elementary tasks, and removing potential problems, the exploration of this scale was done through three studies: in the first study, in order to investigate the factor structure of this scale using varimax (orthogonal) analysis, 322 students of Shahed University who were selected by randomized sampling, completed this scale. Results of this factor analysis indicated 6 appropriate factors. In secondary study, reliability was determined using internal consistency test, test- retest stability of the SERS factors (during 15 days) and the mean inter-item correlation. The result of this stage indicated appropriate reliability of SERS among this sample. In the third study, in order to investigate the construct validity of SERS, scores of SERS and four other instruments: were compared, and the Pearson correlation coefficient for SERS scores and the scores of each of the four above mentioned scales were determined. The results indicated appropriate construct validity of these factors. Finally, regarding literature about factor structure of this scale and psychometric indices of its factors, the authors of this paper suggest the short form of the SERS scale.
