Development and Validation of the Work Effort Scale

In the current article, the development and validation of the Work Effort Scale (WESC), a self-report 10-item scale, is described. Data from several samples are used. The three-factor structure (persistence, direction, and intensity) of the WESC is confirmed by confirmatory factor analysis and reliability is well documented. In accordance with our expectations, we found positive correlations between self-rated performance and global job satisfaction scales and work effort.
