A longitudinal study of the relationship between the five-factor model of personality and workaholism
The present study comprised 1267 nurses who took part in the 2012, 2013, and 2014 waves of the longitudinal study “Survey of Shiftwork, Sleep and Health.” Besides answering questions about work schedules in all waves, the nurses completed the Bergen Work Addiction Scale (BWAS), assessing workaholism, both in the 2012 and the 2014 waves. In the 2012 wave, personality was measured by the Mini-International Personality Item Pool (Mini-IPIP). Intraclass correlation analysis showed a high stability of workaholism across the 24-month follow-up period, although a small but significant increase over time was found. A hierarchical regression analysis was conducted in order to identify factors that could explain change in workaholism across the follow-up period. The results showed that Neuroticism was positively associated with an increase in workaholism. Starting to have at least one child in the household during the same period was negatively associated with an increase in workaholism. Those categorized as stable non-workaholics had lower scores on Neuroticism compared to all other nurses. Stable workaholics had higher scores on Intellect/Imagination than stable non-workaholics.
