An Experimental Evaluation of a Control Intervention to Alleviate Job-Related Stress
在一家卡车运输公司对区域经理进行随机现场实验，发现增强控制感的干预措施仅在主管支持的情况下才能提升控制感知和工作满意度，但对总体幸福感无显著影响。
This article reports the results of a randomized field experiment that tested the effects of a control-enhancing stress intervention among unit managers of a trucking company. Individuals who managed geographically dispersed profit centers were randomly assigned to either an intervention group (N = 34) or a no-intervention group (N = 30). The intervention increased perceptions of control after 4 months, but only for those managers with supportive supervisors. In conjunction with supervisory support, the intervention produced improvements in job satisfaction, but not general well-being outcomes. The impact of the intervention and supervisory support on satisfaction was fully mediated by control perceptions.
