Research assessing the relationship between age and job satisfaction has typically provided mixed results. Inherent problems including limited samples and a failure to control for tenure and affective disposition have potentially contributed to these conflicting results. Moreover, a significant concern has been researchers' focus on detecting linear effects alone. In the current study, we statistically controlled for gender, supervisor and position tenure, quadratic tenure terms, and affective disposition (NA and PA) based on previous research regarding the relationship between these variables and job satisfaction. Finally, we used hierarchical polynomial regression to assess the form of the age-satisfaction relationship. Results confirmed that a U shape best characterized the relationship between age and job satisfaction. Implications of these findings as well as directions for future research are discussed.
