Incremental Validity of Core Self-Evaluations in the Presence of Other Self-Concept Traits

Abstract
Previous research indicates that core self-evaluations demonstrate incremental predictive validity after controlling for several well-established measures of individual differences. The authors extend this research by examining the incremental predictive validity of core self-evaluations relative to three self-focused individual difference constructs—self-esteem, Protestant work ethic, and narcissism—on a broad range of job performance facets, as well as an array of job attitude measures within both U.S. and Chinese cultures. Results indicated that core self-evaluations demonstrate incremental predictive validity for all tested criterion variables in samples of both U.S. and Chinese workers.
