The aim of this study was to examine the associations of type D personality and its components with effort-reward imbalance based work stress and its components. Previously it has been found that both type D personality and effort-reward based work stress are associated with poorer health status and also to be a risk factor for numerous negative health outcomes. The association of Type D personality with effort-reward imbalance hasn't been previously studied. Based on the previous research, we set the following three hypotheses : 1) Higher effort-reward imbalance is associated with type D personality 2) Higher effort and lower rewards are associated with type D personality 3) Higher negative affectivity and higher social inhibition are associated with higher effort-reward imbalance. There were 1285 participants from the Cardiovascular Risk in Young Finns study, who were working full time when the study was conducted and didn't have missing values in the study variables. Work stress was measured with a questionnaire based on effort-reward imbalance model (ERI, Siegrist, 1996). Type D personality was measured with a questionnaire based on DS14-measure (Denollet, 2005). Age of the participants varied between 30-45 years. The hypotheses were tested with logistic and linear regression analyses controlling for age, gender, education and occupational status. In the study type D personality was associated with higher effort-reward imbalance, higher efforts lower rewards. Of the components of type D personality negative affectivity predicted higher work stress but social inhibition was not related to perceptions work stress. The results imply that type D personality is a risk factor for high work stress.
