Personal control is increasingly regarded as an important determinant of health and well-being. While some theorists such as White (1959) have suggested that there may be an intrinsic need to control the environment, others (Rodin, Rennert, & Solomon, 1980) have argued that the evidence suggests that the motivation for control stems from the belief that it ensures positive outcomes. In either case, there is rather compelling evidence that, in general, beliefs in personal control are associated with a myriad of positive health outcomes and lack of control with various forms of ill-health (Miller, 1979; Thompson, 1981). That control processes should also prove important in determining the stressfulness of occupational experiences, then, should not be surprising. This paper reports the development and psychometric assessment of a new self-report measure of employee control.
