Background:
OBQ11 was developed in a Swedish context. To evaluate occupational balance, accurate self-rating instruments in the native language are needed.
Aim:
The aim was to investigate the measurement properties of the Danish version of OBQ11, using the Rasch analysis.
Method:
Data for the analysis of the Danish version of OBQ11 (OBQ11-DK) was gathered online, and all full data records (n 366) were included in the analysis.
Results:
Three items showed non-significant marginal under- or overfit, suggesting a degree of misfit between the data and the Rasch model. Unidimensionality was not reached, though, since the proportion of persons with different estimates were more than 5% and thus the OBQ11-DK cannot be said to assess a person's perception of occupational balance.
Conclusion:
The present version of the OBQ11-DK shows the need for further development and testing and is not tested for test/retest or in clinical samples. The results and small number of items may after modifications and further studies make it feasible to implement OBQ11-DK into settings where the measuring of occupational balance is needed.
