Does workload moderate the association between perfectionism and workaholism: A longitudinal study

The aim of this study is to examine, with a longitudinal design, the moderating role of workload in the relationship between perfectionism and workaholism. It was hypothesized that self-oriented perfectionism (SOP) and socially prescribed perfectionism (SPP) predict an increase in workaholism and that workload may exacerbate this association. Four hundred and thirty workers completed a self-report questionnaire at two different time points, and the hypothesized relationships were tested using structural equation modeling. Overall, SOP and SPP were not associated with workaholism over time. The interaction between SOP, but not SPP, and workload was significant. SOP predicted an increase in workaholism over time in workers facing high workload. Accordingly, SOP may be a risk factor for workaholism when workload is high.
