Past leadership research has demonstrated that transformational leadership has a positive effect on employee task performance and helping coworker behavior. However, among the research on the mediating mechanisms linking transformational leadership and employee work outcomes, little has been done empirically to examine the mediating effect of employee positive moods. This study extends previous research by examining the mediating role played by employee positive moods. Data were collected longitudinally from 282 employees and their immediate supervisors in 10 insurance companies in Taiwan. Results showed that transformational leadership both directly influenced employee task performance and helping coworker behavior and had an indirect effect through employee positive moods.
