工作需求－控制模式與工作倦怠關係之研究：以自我效能爲干擾變數
摘要
Self-efficacy is perceived as the comprehensive and integrated beliefs in one’s capabilities to organize and execute job duty effectively. Present study focus on the role of self-efficacy as a key moderator between the relationship of job stress and burnout. According to Karasek's D-C model, there are two dimensions on job stress: job demand and job control. In additional, the dimensions of burnout in this study include emotional exhaustion and depersonalization. Previous studies on D-C model mainly placed emphasis on increasing job control to diminish symptoms of job stress resulting from job demand. This study explores incremental job control for high self-efficacy in order to decrease job strain. Survey data on 580 government officials demonstrate: (1) Job demand has positive influence on the burnout. (2) Self-efficacy has significant buffering effects between the relationship of job demand and depersonalization. For those with low level of self-efficacy, job control has no significant moderating effects on the relationship between job demand and burnout. In contrast, in term of those with high level of efficacy, job control present significant buffering effects on the relationship between job demand and depersonalization. The study suggests that enhancing the individual's self-efficacy can decrease the impact of job stress on depersonalization.
