The Core Self-Evaluation Scale: Further Construct Validation Evidence

The authors empirically examined two operationalizations of the core self-evaluation construct: (a) the Judge, Erez, Bono, and Thoresen 12-item scale and (b) a composite measure of self-esteem, self-efficacy, locus of control, and neuroticism. The study found that the composite scale relates more strongly than the shorter scale to performance, perceived job complexity, positive affectivity, personal trust, and belief in a just world. However, the short scale performed well and may be more practical in organizational research. The authors conclude that the 12-item measure is better used in research when participant time is limited and that a composite index is better when time is not a constraining factor in the data-collection process.
