The present study tested a scale which measures core self-evaluation and was applied to two samples of Korean military members (Sample 1 N=181; Sample 2 N=280). Analysis indicated that seven items of the original 12-item scale developed by Judge, Erez, Bono, and Thoresen loaded on one factor and were internally consistent. Moreover, scores were correlated, as expected, with the four core traits which have been used as indirect measures of core self-evaluations (viz., self-esteem, generalized self-efficacy, neuroticism, and locus of control), as well as affect and job satisfaction. In sum, results suggest that core self-evaluation can be measured validly in an Eastern culture, and the results should serve as a basis for extending this research in an international setting.
