We investigated the psychometric properties of the Italian version of the Dutch Work Addiction Scale (DUWAS) by using an Italian
sample (N = 1,027) and a comparable Dutch sample (N = 7,523). We first conducted multigroup confirmatory factor analysis and reliability
analysis. We then examined the correlations of the DUWAS with job demands, work-family conflict, job-related affective well-being, and
psychological and physical strain. Results showed that a two-factor solution of the DUWAS was equivalent across the Italian and Dutch
samples, with data supporting factor variance and covariance equivalence in addition to metric equivalence. Internal consistencies of the
DUWAS and its subscales were adequate, and test-retest reliability showed a strong stability of the measure at one year. The DUWAS and its
subscales showed a pattern of correlations in the expected direction with the adopted criterion measures. Overall, the Italian version of the
DUWAS shows adequate validity and reliability
