Purpose. To establish the construct validity of the Danish version of the Canadian Occupational Performance Measure (COPM). Methods. A cross-sectional study was performed in two settings, a regional hospital and a rehabilitation centre in a community. Including adult clients with a variety of diagnoses, we assessed construct validity by correlating the COPM to the Occupational Self-Assessment (OSA), the five-item World Health Organization Well-Being Index (WHO-5), and the EuroQol-five domainfive level questionnaire (EQ-5D-5L). Further examination of the comparability of the OSA and the COPM was performed in two ways. First, an interrater agreement of the theoretical correlation of the 21 OSA items and the three areas of the COPM was conducted. Secondly, we examined the compliance between the prioritized occupational performance issues (OPIs) and items of the OSA prioritized for change. Results. The study included a total sample of 112 participants with more than half of the participants (56%) recruited from the hospital. 109 participants had measurements for both COPM and OSA (44% males) with a mean age of 64.7 years (range 16-96 years). All correlations, between the COPM and the OSA, the WHO-5, and the EQ-5D5L, were low or negligible (r < 0:50). Manual examination confirmed a difference in the constructs of the OSA and the COPM. This was demonstrated by a negligible interrater agreement between the items of the OSA and the areas of the COPM, and differences in the prioritized OPIs and OSA items, even if there were some resemblances, were found. Conclusions. This study suggests that the construct of the COPM provides data different to those obtained with the standardized measurements included for comparison. The present study supports the assumption that the COPM can detect unique OPIs that clients want to do, need to do, must do, or are not satisfied with the way they do.
