SALINA, Kan. - Most characteristics of the "Type A" personality are linked to increased work stress. But, now there may be one important exception.
High scores for aggression, hard-driving, and eagerness-energy were all associated with high job stress. These three Type A characteristics were also linked to "effort-reward imbalance"--a key contributor to work stress.
According to a study in the January Journal of Occupational and Environmental Medicine, official publication of the American College of Occupational and Environmental Medicine (ACOEM), In contrast, workers who scored high on leadership had lower work stress. High leadership was linked to high work effort, but also to high work rewards. High leadership was also associated with high job control, which may help to reduce work stress.
The researchers analyzed the relationship between Type A behavior and work stress in 752 Finnish workers. In contrast to previous studies, they broke Type A behavior into four dimensions: leadership, aggression, being "hard-driving," and eagerness-energy.
The Type A personality--with characteristics like aggression, time urgency, and competitiveness--has been linked to an increased risk of heart disease. Type A behavior may also be a risk factor for high stress on the job. Especially if they feel like they're not in control, Type A personalities may respond by becoming over-involved in work.
High leadership protects against work stress, the new study suggests. Leadership may be associated with a good balance between job effort and rewards and a higher level of control over work. In contrast, other three Type A characteristics--aggression, hard-driving, and eagerness-energy--are linked to high work stress and effort-reward imbalance.
These personality characteristics should be considered in designing programs attempting to address work stress, Hintsa and co-authors believe. For example, since leadership increases job control, giving employees a stronger say in work decisions help to reduce job stress.
