Abstract

This study attempted to investigate the moderating effects of attitude toward money(MES) and intrinsic and extrinsic motivational orientations(WPI) as individual differences variables which have not been popular in organizational behavior research, on the relationship between perceived job characteristics(autonomy, challenge) and job involvement and organizational commitment. Relevant variables were measured by survey questionnaires from a sample of 430 employees in Korea, and to detect interaction effects and control the nuisance effects of demographical variables moderated hierarchical multiple regression were run with obtained data. Results indicated that both attitude toward money and extrinsic motivational orientation showed significant moderating effects on the relationship between job characteristics and organizational commitment. Intrinsic motivational orientation was also a moderator for the relationship between job characteristics and job involvement. The implications of this results and the potential use of the two moderator variables were discussed.
