Research remains divided over the issue of whether job control acts as a buffer or not.Terry& Jimmieson (1999) extensively reviewed this literature and concluded that the majority of both cross-sectional and longitudinal studies found little support for the interaction in predicting employee adjustment (as measured by job satisfaction, for example). They conclude, perhaps surprisingly, that the strongest support for the interaction is based on studies using objective indicators of job features and/or strains (e.g. Dwyer & Ganster, 1991; Fox et al., 1993). Some support has also been found in studies using experimental methods (Perrewe & Ganster, 1989), suggesting that control may buffer the effects of the demands of specific work tasks. Research looking at cardiovascular outcomes has seldom directly tested the interaction effect, but where it does, Terry & Jimmieson conclude that the findings have generally not been significant.
