Demand-control-person: integrating the demand-control and conservation of resources models to test an expanded stressor-strain model.
We propose an expanded stressor-strain model that explicitly incorporates person characteristics, the Demand-Control-Person model. This model integrates Karasek's traditional Demand-Control model with Hobfoll's (1989) Conservation of Resources theory. With participants from two organizations, we tested the moderating role of emotional stability in conjunction with two job demands (i.e., uncertainty and time pressure) and control (i.e., decision latitude) in predicting two forms of strain (i.e., job dissatisfaction and disengagement). Our findings support the expanded Demand-Control-Person model, such that a significant three-way interaction emerged for uncertainty and time pressure. As predicted, the traditional Demand-Control model only held among individuals high in emotional stability, such that low-emotional stability individuals did either not benefit as readily from decision latitude or were more susceptible to job demands when they had decision latitude. Thus, the Demand-Control-Person model may provide a more comprehensive model and consistent prediction of the effect of stressors on strain as determined by individual characteristics.
