THE CORE SELF‐EVALUATIONS SCALE: DEVELOPMENT OF A MEASURE

Despite an emerging body of research on a personality trait termed core self‐evaluations, the trait continues to be measured indirectly. The present study reported the results of a series of studies that developed and tested the validity of the Core Self‐Evaluations Scale (CSES), a direct and relatively brief measure of the trait. Results indicated that the 12‐item CSES was reliable, displayed a unitary factor structure, correlated significantly with job satisfaction, job performance, and life satisfaction, and had validity equal to that of an optimal weighting of the 4 specific core traits (self‐esteem, generalized self‐efficacy, neuroti‐cism, and locus of control), and incremental validity over the 5‐factor model. Overall, results suggest that the CSES is a valid measure that should prove useful in applied psychology research.
