A Rasch analysis of the Danish version of the occupational balance questionnaire (OBQ11)

Abstract

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.
