| Abstract: | Abstract: The present study investigated the factor structure of the 10-item version of
the Dutch Work Addiction Scale (DUWAS). The DUWAS-10 is intended to measure workaholism
with two correlated factors: working excessively (WE) and working compulsively (WC). The
factor structure of the DUWAS-10 was examined among multi-occupational samples from the
Netherlands (n=9,010) and Finland (n=4,567) using
confirmatory factor analysis (CFA). CFAs revealed that the expected correlated two-factor
solution showed satisfactory fit to the data. However, a second-order factor solution,
where WE comprised the first-order factors “working frantically” and “working long hours”,
and WC the first-order factors “obsessive work drive” and “unease if not working”, showed
significantly better fit to the data. The expectation of factorial group invariance of the
second-order factor structure between the Dutch and Finnish samples was also supported.
Moreover, factorial time invariance was observed across a two-year time lag in a
sub-sample of Finnish managers (n=459). In conclusion, the DUWAS-10 was
found to be a comprehensive measure of workaholism, meeting the criteria of factorial
validity in multiple settings, and can thus be recommended for use in both research and
practice. |
