(2015)The aim of this study was to test the associations between job satisfaction and job strain, defined according to Karasek's Job Demands-Control Model, as well as type D personality traits. Previous studies have mainly focused on job characteristics and other external circumstances when studying wellbeing at work. The relationship between occupational wellbeing and individual factors such as personality traits has received less attention. Based on previous studies five hypotheses were set: 1) type D personality is associated with lower job satisfaction, 2) type D personality is associated with higher job strain, 3) job strain is negatively associated with job satisfaction, 4) job control moderates the association between job demands and job satisfaction, and 5) the association between type D personality and job satisfaction is mediated by job strain. The data consisted of 1117 participants of the Cardiovascular Risk in Young Finns study. All participants were full-time employed Finns aged 30 to 45. Type D personality was measured with a modified questionnaire based on DS14 (Denollet, 2005), job control was measured using items from the Job Content Questionnaire (Karasek, 1985) and job demands was measured using items from the Occupational Stress Questionnaire (Elo et al, 1990). Job satisfaction was measured with a single-item scale. The hypotheses were tested using linear regression analyses. The effects of gender and education level were controlled for. Employees with type D personality were found to experience lower job satisfaction and higher job strain when compared to non-type D counterparts. Of the two type D traits, only negative affectivity was a statistically significant predictor of job satisfaction. Job strain was associated with lower job satisfaction. The association between negative affectivity and job satisfaction was partly mediated by job strain. Based on these results it seems that type D personality, especially negative affectivity and job strain may be risk factors for lower occupational well-being.

(2015)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.
