Mood and organizational citizenship behavior: the effects of positive affect on employee organizational citizenship behavior intentions.

This study, involving 139 employees from a variety of industries, organizations, and positions in Singapore, measured the effects of mood on the intentions of employees to contribute actions that are organizationally desirable but are not part of their formal job requirements (organizational citizenship behavior). After effects of established patterns of historical organizational citizenship behavior, demographic characteristics, and employee positive and negative affectivity had been controlled, stepwise regression analysis revealed that the amount of positive affect currently experienced by an employee significantly influenced the employee's intention to perform specific acts of organizational citizenship.
