Subjective Well-being and Job Performance: Testing of a Suppressor Effect

Abstract

This is a four-year follow-up study on the relationship between the cognitive and emotional components of subjective well-being (SWB) and job performance. We hypothesized a positive relationship between these variables and job performance. The sample consisted of 170 managers of a Spanish company in the Information Technology and Communication (ITC) industry. The cognitive component of SWB was assessed with the Satisfaction with Life (SWL) scale and the emotional component with the SPANE scale. Two independent ratings, one from the direct supervisor and another from the HR manager, served as evaluations of job performance during four years in a row. Results showed that the two components of SWB predicted job performance over the four years. Additionally, when the two components are entered in a regression equation the validity increases over time as a consequence of a suppressor effect on the cognitive component of SWB. Finally, we discuss the implications for the theory and the practice of SWB at work.
