Validity of a brief workaholism scale

The current study contributes to our understanding of workaholism as a negative construct, and to its measurement by examining the psychometric properties of a short 10-item workaholism scale called DUWAS (Dutch Work Addiction Scale). Confirmatory factor analyses were carried out in a heterogeneous sample of 2,714 employees from the Netherlands (n= 2,164) and Spain (n= 550). The results confirmed the expected two-factor structure of workaholism: working excessively and working compulsively. Moreover, multi-group analyses showed that this two-factor structure was invariant across both countries. Lastly, negative correlations among workaholism and psychosocial well-being (i.e., perceived health and happiness) are indicators of the negative nature of workaholism.

Validación de una escala breve de adicción al trabajo. El presente estudio contribuye a la comprensión de la adicción al trabajo como un constructo negativo, y a su evaluación, examinando una medida reducida de adicción al trabajo denominada DUWAS (Dutch Work Addiction Scale). Para ello, se han realizado análisis factoriales confirmatorios en una muestra heterogénea de 2.714 trabajadores holandeses (n= 2.164) y españoles (n= 550). Los resultados confirmaron la estructura bifactorial de la adicción al trabajo: trabajar excesivamente y trabajar compulsivamente. Además, los análisis multigrupo mostraron que esta estructura bifactorial era invariante a través de ambos países. Finalmente, las correlaciones negativas obtenidas entre la adicción al trabajo y el bienestar psicosocial (esto es, la salud percibida y la felicidad) son indicadores de la naturaleza negativa de la adicción al trabajo.
