Effect of job demands and social support on worker stress: a study of VDT users

Abstract
This study examined the effect of job demands (quantitative workload and computer-related problems) and social support (supervisor and co-worker support) on stress of VDT users. A survey questionnaire was administered to employees of three public service organizations. Two-hundred and sixty-two office workers participated in this study. Results showed that job demands (quantitative workload and computer-related problems) had a direct effect on psychological complaints of VDT users. On the other hand, co-worker support did not affect worker stress. Supervisor support was a buffer against worker stress both in the low and high job demands conditions. However, supervisor support did not have any interactive buffering effect on the relationship between job demands and worker stress.
