Abstract

The purpose of the present study was to examine the psychometric properties of 12-item Core Self Rating Scale (CSES) developed by Judge, Erez, Bono, and Thoresen (2003). Two hundred nineteen employees from Shahid Chamran and Jundi Shapour Medical Sciences Universities surveyed were randomly selected. Cronbach's alpha was 0.71 and item-total correlations were ranging from .25 to .61, indicating high internal consistency. The validity of the scale was confirmed through multiple ways. First, consistent with expectation, exploratory factor analysis using principal components and varimax rotation showed that four core traits including self esteem, generalized self-efficacy, locus of control, neuroticism and loaded on a single factor, significantly. Second, confirmatory factor analysis indicated that except for one item, all items of CSES loaded on a single factor, significantly. Third, CSES was positively correlated with self-esteem, generalized self-efficacy, and locus of control, and negatively with neuroticism, indicating convergent validity of the CSES. Fourth, CSES was significantly correlated with job satisfaction, one of very important criteria in I / O psychology, indicating empirical validity of the CSES. Fifth, hierarchical regression analysis revealed that CSES beyond core self ratings score and four core traits explained the job satisfaction variance significantly. In sum, the results showed that the CSES is a valid and reliable scale for measuring Iranian core self evaluations.
