Validity and Reliability of Core Self-Evaluations Scale in Iranian Employees

By Seyedesmaeil Hashemi Sheykhshabani


AbstractThe purpose of the present study was to examine the psychometric properties of 12-items Core Self Evaluations Scale (CSES) developed by Judge, Erez, Bono, and Thoresen (2003). Two hundred nineteen employees from Shahid Chamran and Jundi Shapoure Medical Sciences Universities randomly selected were surveyed. Cronbach 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, confirmatory factor analysis indicated that except for one item, all items of CSES loaded on a single factor, significantly. Second, CSES was positively correlated with self-esteem, generalized self-efficacy, and locus of control, and negatively with neuroticism, indicating convergent validity of the CSES. Third, CSES was significantly correlated with job satisfaction, one of very important criteria in I/O psychology, indicating empirical validity of the CSES. Fourth, hierarchical regression analyses revealed that CSES beyond core self evaluations 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
