RELIABILITY AND VALIDITY OF THE TURKISH VERSION OF THE DUTCH WORK ADDICTION SCALE (DUWAS-TR)

The aim of this study is to adapt the dutch work addiction scale (duwas) into turkish, which was developed by schaufeli, taris ve bakker (2006) and to test the original two-factor structure with the present sample. the participants of the study were 379 employees (146 female / 233 male) who have different kinds of occupations. ages ranged from 18 to 61 and the mean age is 34.45 (s=8.66).the psychometric properties of the scale were examined by item analysis, internal consistency and confirmatory factor analysis methods. the results of the confirmatory factor analysis showed a reasonable data fit with the two hypothesized duwas-tr domains of “working excessively” and “working compulsively”. goodness fit indexes were found as χ2/sd=3.44, agfi=0.087, gfi=0.92, cfi=0.91, ifi=0.91, rmsea=0.080. the reliability of the scale was also satisfactory, showing good internal consistency. internal consistency coefficient for the whole scale was .85, for “working excessively” .76 and for “working compulsively” .74. these findings indicated that the turkish form of duwas-tr is a valid and reliable instrument to assess work addiction
