Cross-cultural adaptation of the Work Role Functioning Questionnaire 2.0 to Norwegian and Danish.

This is a first step towards full validation in Denmark and Norway, so the findings cannot be treated as complete evidence that the questionnaire is valid there. The psychometric analysis was based on 40 Norwegian participants, and the paper notes that small pre-test groups may be too homogeneous. The Norwegian sample scored very high on the questionnaire, and the authors say this may mean the measure does not separate people well. The paper states that reliability coefficients were all above 0.80, but the table reports 0.79 for the physical demands subscale. The paper states that missing or not applicable responses were below 15% for all subscales, but the table reports 15.0% for physical demands. The supplied text reports psychometric results only for the Norwegian sample. The authors say future studies will examine validity, reliability, responsiveness and differential item response, so this paper does not establish those properties.

Do not treat the Norwegian and Danish WRFQ 2.0 as a validated measure. The paper says this is a first step towards full validation, and future studies will examine validity, reliability and responsiveness.
