Does job control act as a stress-buffer when employees’ type and level of work selfdetermination is taken into account? It was anticipated that job control would only be stress-buffering for employees high in self-determined and low in non-self-determined work motivation. In contrast, job control would be stress-exacerbating for employees who were low in self-determined and high in non-self-det...

In a distributed object oriented hierarchical shop control system there are many ways of organizing the interactions between supervisory controllers and subordinate controllers De pending on what model of job control is used objects will be allocated di erently among the levels of control and the interactions between controllers will vary considerably This paper describes four models of job con...

The present 3-wave longitudinal study was an examination of job-related learning and strain as a function of job demand and job control. The participants were 311 newcomers to their jobs. On the basis of R. A. Karasek and T. Theorell’s (1990) demand–control model, the authors predicted that high demand and high job control would lead to high levels of learning; low demand and low job control sh...

The Job Demand-Control model postulates that job control attenuates the effects of job demands on health and well-being. Support for this interactive effect is rather weak. Conceivably, it holds only when there is a match between job control and individual characteristics that relate to exercising control options, such as locus of control, or self-efficacy. This three-way interaction was tested...

Previous meta-analytic findings have provided ambiguous evidence on job control as a buffering moderator of the adverse impact of job demands on psychological well-being. To disentangle these mixed findings, we examine the moderating effect of job control on the adverse effects of quantitative workload and emotional dissonance as distinct work-related demands on emotional exhaustion over time. ...
