Based on this definition, the DUWAS (Dutch Workaholism Scale) is introduced, a brief two-dimensional self-report instrument that includes two correlated subscales of five items each: Working Excessively (WE) and Working Compulsively (WC). Using a national Dutch database (n = 11.060) cut-off scores were computed that allow a classification of levels of workaholism. Analyses (n = 1.166) reveal that particularly the combination of high scores on both WE and CW is unfavorable. It is concluded that the DUWAS is a reliable and valid inventory that can, for instance, be used as a screening tool to identify workaholic employees., UL https://www.aup-online.com/content/journals/10.5117/2011.024.001.043
