Abstract
Introduction
To establish the responsiveness of the Danish version of the Canadian Occupational Performance Measure (COPM-DK).
Method
A cross-sectional study was performed in three Danish settings, including 88 clients, 40 men, aged 16–90 years, with a variety of diagnoses. To determine construct responsiveness, the mean changes of the COPM performance and satisfaction score (COPM-P/S) were compared and correlated with the mean changes in the five-item World Health Organization (WHO) Well-Being Index (WHO-5) and the EuroQol–five domains–five levels questionnaire (EQ-5D-5L). To determine the responsiveness, data were analysed with ROC curves to establish the optimal cut-point values for the COPM-DK scores. Minimal important change (MIC) was assessed in relation to anchor-based questions.
Results
The mean change for COPM-P/S was 3.1 and 3.0, respectively. Small positive correlations were found between the COPM-DK scores and the WHO-5 and EQ-5D-5L scores. The AUC were 0.76 and 0.75, respectively. The optimal cut-point values for the COPM-P/S-scores based on either all positive answers or to the two highest, were 1.2 or 4.20 (COPM-P) and 1.67 or 5.80 (COPM-S), respectively
Conclusions
The capability of the COPM to detect changes in perceived occupational performance issues is supported. We recommend an MIC on 3.5 points on both scales.
